Team XP Deus Romania have started the detecting season on a positive

The spring is here, so the Romanian Military Archaeology and Pro Detectie team joined forces for a day’s metal detecting, hoping start the season on a positive note and hopefully bring some new XP Deus discoveries to light.

We opened our spring season with a light hike, exploring an area well known to us, just in order to warm up, and get back into shape after a long and solitary winter. We were detecting in the field without any kind of expectations, mostly chatting about this and that, digging signals and making jokes, sometimes metal detecting is not all about great finds, it is about spending time with friends and enjoying life and the great outdoors.

There were 6 of us on the field, each finding few modern coins, and all using the Deus, some being very experienced with it, others being very new and enjoying their new machine.

Romanian XP Deus metal detecting clubs

At one point, one of our ‘’beginners’’ started to dig out several items of melted bronze, that was enough for us to start a more intense search of the find spot. In the past we have only discovered military items in this area, so it was a surprise to find traces of an older context.

XP Deus finds ancient treasure in Romania

The first interesting target, was a bronze ring having very fine detail, we would say probably coming from a Medieval time-frame. Shortly after the ring, and at about 50meters from the place of its discovery, we found several bronze artefacts: A very small axe head, a piece that we believe could be some sort of buckle, a small chisel and a fragment of an ornament, having one end sculpted in the form of a dog’s head; all of them in bronze.

The small axe was missing the blade’s edge, when we handed our finds into the museum they told us a lot about the items. They said the blade was most probably intentionally removed, during some sort of ritual, in order to not offend or threaten the god. They went on to say artefacts were coming from a scattered time period, and this was normal as the area had been inhabited for many generations dating back way beyond the Medieval period.

XP MI-4 pin pointer product review

When XP announced the MI-4 pin point probe I was a little confused, as I already have an MI-6 and love the radio link to the Deus, why would I want to change.
Then the whole concept of the XP MI-4 was explained to me and it now makes perfect sense.

The MI-4 pin point probe from XP metal detectors | What you should know
XP have a top end product with the MI-6, but I guess that is really channelled towards the XP Deus users as it has the radio link and the expert “Deus only” features when connected.
If you do not yet own a Deus, why pay extra for the features you may not require.

You should read this before you buy a metal detecting pin point probe

The MI-4 has been designed, to offer a top quality reliable product to those who do not feel the need for a radio link in a pin point probe.

What features does the XP MI-4 pin point probe offer ?
Would you believe it has just as many as the MI-6 in the stand alone mode :

A Rechargeable lithium battery.
6 Programs.
3 power levels.
2 detect audio modes, Pitch or Pulse.
5 Minute time out mode – saves battery life.
Fast De-tune for large targets or difficult ground.
All the parts are quickly replaceable.
Waterproof up to 6 meters.
360 Detection.
A Lanyard.
A rotating holster.
2 year warranty.
The MI-4 floats.

Using a pin point probe is essential always insist on XP products

So what’s in the box

Mi-4 pin pointer
Rotating Holster with belt clip
Lanyard and USB charging lead

XP metal detectors - leading manufacturer in metal detecting products
The Rotating Holster

The rotating holster is a great idea as it can be worn on a belt or webbing, allowing you to rotate the probe using a ratchet mechanism, this is ideal if you find the pin pointer is uncomfortable when bending down.

MI-4 pin point probe | Just look at these features
USB Charging

Fast charging from any USB port, battery life is up to 30 hours, depending on LED / Audio / Vibrate selected.
30 Hours is a long time considering you only switch the probe on for a minute while recovering a target.

Locating a buried target using a pin point probe is much easier

The link break feature

I would like to talk about is EMI, or to be exact EMI that you cannot hear – Silent EMI.
Did you know that many probes have always used an open circuit even when they are switched off, this can silently affect the detector up to 2 meters away, unless you are looking for it you may never know this is happening, this problem is especially noticeable when using PI machines.
With the MI-4 and MI-6 the open circuit link is broken as soon as the probe is switched off eliminating any “Nulling” problems, allowing your detector to work at its optimum performance levels.

Every professional metal detectorist should have an MI-4 poin point probe from XP metal detectors

I have owned many probes over the years, and to be fair they have all done a good job, but every one of them have had some points I have not been happy with, whether it be build quality, reliability, features or performance.

I have been testing the XP MI-4 pin point probe and can honestly say it is a good tool for the job, it’s rich in features has a chunky robust feel with excellent build quality, so if you are in the market for a pin pointer you won’t go far wrong with the MI-4 from XP Metal Detectors.

Understanding the MI-6 menus and features

Accessing the functions on the MI-4 is exactly the same as the MI-6, except there is no option 7 in the menu, the video below shows the full range of MI-6 features.
It helps give a better explanation into how good this product really is.

Pascal Lebrrun rally in Belgium 2018

XP metal detectors were kindly invited to attend the Pascal Lebrrun rally in Belgium, it was gratefully accepted as this would be another opportunity to meet our customers, offer assistance, answer questions and above all thank them for supporting us and our products.

Rallye international Pascal Lebrrun 5000 hunters since 1999

The rally got underway and everyone met up at base, which was a large farmyard with refreshments and seating…however this was just the meeting point, the fields were 6 kilometres away, the rally organisers had arranged buses to take everyone to the site, which was a massive task for over 400 people, but everything went to plan.

A little about Pascal Lebrrun

Pascal was a very respected member of the metal detecting community, he worked very hard to maintain a strong relationship with the Belgium authorities and Archaeologists, very much like a one man NCMD or FID.
His life ended tragically when a WWII bomb exploded.
The original Pascal Lebrrun rally was held so his family could pay for the funeral expenses and help financially support them, now the event has continued and still sealing bonds between metal detector users and the Belgium archaeologists.

Metal detecting in Belgium at the Pascal Lebrrun rally

The rally fields were perfect, with gentle grass slopes easing down to a river, there was even an ancient cave at the bottom.
Unlike UK rallies, there are strict laws in Belgium regarding metal detecting, so the event was based around finding buried tokens and then exchanging them back at base for prizes, kindly the local Archaeologist was on site to identify and record any natural finds that were discovered.
The token hunt started with a mad rush, spirits were high and it was clear everyone was having fun, cold beers were available all day I think this was just to cool everyone down as it was over 20 degrees in the sun.

Metal detecting in the hot sun with an XP Deus

After the first event, everyone caught the buses back to base for a gourmet standard amazing lunch, followed by apple pie and the first token exchange and the raffle draw, then it was back to the fields for the second hunt. This was a different field, once again with an ancient track running through it and breathtaking scenery.

Meet fellow metal detector users from all over the world at an international metal detecting event.

The second token hunt ended after 2 hours and it was then time for something we had never seen before….A pin point only hunt.

This consisted of a roped off area with buried chunks of metal, the aim was to find as many targets as possible with a pin point probe, the rules were you could not stand up during the hunt, I think this was a welcome challenge for those who had been drinking since 8.30 in the morning.
This indeed was the event of the day and so much fun.

Pascal Lebrrun metal detecting event pin pointer hunt

After the pin point hunt had ended  it was time for the final prize draw back at base, some fantastic items were on display, then it was time for more food. This time it was a barbecue once again to the highest standards, we continued until about 10.00 o’clock and that was us finished, but the party was still going way beyond that.

Metal detecting pictures of XP Deus users at a Belgium rally

What a fantastic event and a massive thanks to the organisers who worked so hard to make this happen, it was good to see that at least 80% of detectorists were using XP, everyone I talked to were more than happy with our products and had no intentions of changing. Thanks for all your feedback regarding future requirements and a massive thanks for your warm hospitality and for supporting XP, we hope to meet up with you all again very soon.

2 Bronze aged axe heads

Sue had an amazing find with her XP Deus when she attended the Southern Seekers metal detecting event in Salisbury, well I say an amazing find, it was actually amazing finds. She found not one but two Bronze aged axe heads less than a foot apart.
The day started off very quiet, Sue used her XP Deus on the Deep program it wasn’t long before the machine gave a suspicious signal with a disrupted XY line with several angles, but once she worked the coil over the exact centre it was soon apparent that it was worth digging, but she had no idea it would be treasure.

The XP Deus metal detector can find deep treasure
At about 9″ deep she instantly knew what it was looking back at her…A Bronze aged axe head in fantastic condition, once the celebration was over with her husband Chris she hit another signal just inches away, it was another axe head.
Quickly the marshals marked an area for them to search, others looked on as they scanned the area for more targets, sadly nothing else came up.

Look at this amazing ancient treasure found with an XP Deus metal detector

I cant believe my luck Sue said she picked up lots of information from the XP skill School day near Newbury organised by Leisure Promotions and believes it really helped her become confident with the XP Deus.

Sue finds ancient treasure from the Bronze age
The axe heads are believed to be middle bronze age and known as Palstave would have been made in a mould, not long back one of our XP testers Gary Cook found an in tact axe mold which is a very rare find.

Rare bronze aged axe head molds found with an XP Deus
Once moulded they would have possibly been tethered to a wooden handle with leather then a tree resin applied to harden the fixing, Ash was a common wood used back then.
Here is an interesting article about axes through the ages  The History of the Axe

XP Deus metal detectors | Another treasure story
Because 2 items have been found it is declared as treasure, Sue now has 14 days to report the find to her local FLO or the Museum.

This whole event taught me to trust the Deus and never assume

Ancient coins found with an XP Deus metal detector

I guess for most of us the real drive related to metal detecting is connecting with the unknown

It’s amazing to think that we will never know what remarkable treasures the soil hides.
I must admit that many times I have the obsessive thought that maybe something incredible could have laying buried just 10cm outside my Deus search swing, sometimes it’s hard to stay focused when that thought is in your mind. This article is kind of a follow up from my earlier post called “Metal detecting trust your feelings” recently published on the XP Classroom blog.
People know me as Vorax I am a proud member of the Pro Detectie association in Romania, as a group we work alongside the local museums to protect our countries heritage and share the history we have uncovered, without the assistance of high performance metal detectors, none of our amazing discoveries would have seen the light of day.

I must admit that when I began metal detecting I had a clear vision, and that was to find something truly memorable and important for my country’s history and heritage. I have had some very good luck in my ”MD career”, I can’t deny that, sometimes I just become complacent about finds, even if they were pretty nice. As it often happens in life, my period of numb self-sufficiency changed in a blink of an eye on a normal day.

Searching the desserted forrest with the XP Deus metal detector

For some months I’ve been searching inland and beaches, my inland search had been mainly exploring the same area, in which are three forests close to each other, one considerably big and two smaller. I spent about two months prospecting the big forest, without any notable finds, beside few modern coins and items, mostly cheap jewellery from ca. 1900.  I kept going back there, because the landscape was beautiful and the forests are very clean, every visit was a true joy ride. After another month in the big forest, I decided to try to change my luck and start to search the smaller forest out of the three.

The first day in the small forest was no different; very clean soil, very few signals. At some point, I decided to work towards the opposite side, more exactly an area clearly showing as odd shaped object on my GPS screen.

After a short walk my GPS told me I had reached the spot, believe it or not but the very first signal there, was the one that changed my fortune.  A very strong and stable signal, jumping across three tone ranges on my custom Deus Fast program. From the beginning I was sure that the signals were coming from multiple separate targets, I was receiving a clear 65-70 value, but also a collection of faint ones at about 40-55. I initially thought that most probably would be some sort of shallow trash pit, but I began to dig with a big grin on my face, why the big grin ? All I can say is I was having an unexplainable feeling that something uncommon was in that pit… and I was right.

After digging down, I spotted the ”grey light”, I was sure that I was seeing Silver in the hole. Multiple large objects of Silver were sat there at around 10/15cm deep right before my eyes: Brooches with gem stones and Gold detail, rings and other various jewellery, both in Silver and Gold. I was stunned, but needed to compose myself because more signals were still there in the same hole. I detached the lower rod from my Deus and started to work very slowly and methodically with just the coil …..Genius idea !

Ancient jewellery found with an XP Deus metal detector

At a glance I estimated the jewellery to date back to somewhere to the medieval period, but something even more incredible happened. When the jewellery pieces were all recovered, I started to pick up coins, which were located under the jewellery hoard, and they were not common coins, but 13 silver Thasos Tetradrachm, dating back to about 400-480BC.

Ancient coins found with an XP Deus metal detector

I was in a dream state of mind, it was an unbelievable moment and a truly unique feeling. When I handed all the materials to the National Museum of Romanian History, they suggested that the mixed periods could have been related to a medieval thief and some stolen goods.

Trust your xp Deus metal detector it will lead you to treasure
Possibly a wealthy medieval family having some ancient coins in their collection, who had been possibly robbed. But the most interesting piece from the hoard, was a small oval Silver medallion, displaying some engraved inscriptions related to Saint Ambrose and containing some bone fragments and human hair.

Thanks XP to my Deus and indeed to XP for making a powerful lightweight machine, capable of working the most difficult terrain. After the discovery buzz was gone, I understood that the fast target separation of the Deus made me aware that multiple targets were in the hole, perhaps with a slower machine it would have registered something completely different. This whole event taught me to trust the Deus and never assume! That jumpy signal…. You know it could be trash but on the other hand it may not !

Terry finds a unique Iron age brooch with his XP Deus

Terry finds a unique Silver Iron age brooch with his XP Deus

On a warm November afternoon in 2017 i thought i would get a couple of hours metal detecting in, so off I went to a permission I have done a few times before.
All I found was the usual buttons and a Vicky penny so decided to go up the hill and try my luck. After a short while I got a great signal and started to dig down about 6-7 inches,when I turned the turf over there it was gleaming in the sunlight I thought it was a Roman brooch so I took some pictures, carefully removed it from the clod and put it in my finds pouch.

I contacted my local FLO and could not believe what they were saying

I carried on for another hour or so but the excitement got to much for me so I packed up and went home. I contacted my Finds Liaison Officer and sent him the photographs. I was really not prepared for the reply.

“WOW that is a great brooch, there are similar brooches called P-Shape which are Roman, these examples have a separate spring that is wrapped around a detachable bar mounted at the top of the head.

However your example has an integral spring that has been cast on the bow, this is typical of the La Tene II type brooches of the middle Iron Age and are very rare. There are only 11 on there database for the whole of the country, none are silver. there are silver examples known but I’ve never seen one, even in a museum”.

Metal detecting trust your feelings

Follow to your soul and you may be rewarded

I must say from the moment I picked up my first machine metal detecting has been a very satisfying hobby. No, not economically satisfying, but more like a window for the soul….. and also bonus for my country’s historical heritage.

I firmly believe that I’m a lucky guy, besides having a loving family, I’ve encountered several situations that have made others say ‘’man, you’re truly lucky’’.
So, keeping that in mind, I’ve entered the metal detecting world with a slightly different outlook to many others.

I started the hobby with a cheap machine, just in order to see if the activity would suit me. Even in the early days, I was struck by an image, an advertising image, it was a new metal detector that pushed the boundaries to another level; that detector was the XP Deus, and from the very first moment I saw it, I knew that it will become MY metal detector. Lots of other manufacturers based their advertising around glossy pictures and the promises of more performance and deeper treasure, which even as a beginner made me think twice. But this machine had no hype, just facts and the best advertising campaign available…..The customer.

Some recent XP Deus finds
XP Deus users have recovered some fantastic treasures over the years - this is just a small example

The day came when I finally got my hands on my very own Deus, and since then a long series of lucky shots accompanied me on my journey. I won’t describe every nice coin or interesting artefact I’ve discovered, but I will over a series of articles show you my more important finds that have kept my passion for History alive, and I think the equipment I am using is partly responsible for this. I say partly because there is a lot of luck involved with this hobby…..Plus I believe you can change your luck by focusing on your own feelings, I will explain more in a while.

In another article I will talk about a very interesting Medieval hoard consisting of Gold and Silver jewellery, plus all sorts of other valuables, this time I present to you a ‘’classic metal detectorists dream’’, a big, silver coin hoard.

The day

It was a cold January day with clear skies, in my mind I pictured detecting a forest, so that was just what I did. I had been looking at a particular site for some time so I headed in that direction. Most of the time I go detecting alone so on this day it was just me, my little jeep and the Deus.

Vorax the lucky guy
metal detecting can be a lonely hobby if you find treasure there is no one to share the experience with....Just you and your XP Deus

After few hours of searching with my XP Deus I had very few signals (mostly trash or modern coins) I started to have a strange feeling, it’s hard to explain, a mixture between energy and desire, I have experienced this many time before: I felt that something good will happen to me on THAT day, in THAT forest. I have talked with people and read many times about the detectorists having such feelings, or should I say strong sensations, I personally believe this is something we all have the abilities to uncover.
With this feeling in my mind, I continued to search with only 2 available hours of daylight left, (in January everything is dark by 5.00pm, and you don’t want to be alone in the forest…).

Surprisingly or not, that good feeling was once again spot on: A very loud and jumpy signal came from base of a tree, I carefully excavated the area and there it was a hoard of silver coins, most of them Ottoman but also Austrian, Spanish, Russian and few Romanian ones. A total of 596 coins cumulating 12,5 kg of silver. I was in shock but not 100%, because in a strange way having carried the “Detectorists feeling” with me I knew that something incredible was going to happen, so in a way it was not a complete surprise.

Follow your dreams
XP Deus finds another amazing treasure

The entire hoard was handed to the Romanian National Museum of History in Bucharest (I attach also a document related to that) and for me it was just another incredible day that gave me incredible memories. I’m lucky, yes, it’s true, because when I get old I will have some very interesting stories to tell; hopefully I will be believed…..

Certificate of recording

My advice to fellow detectorists out there is follow your feelings, if something feels different while detecting don’t ignore it, there may be greater powers out there giving you a sign.

Thanks XP for such incredible machine, which for me has not only been the compass to my success but made this hobby so much more enjoyable.

XP Deus HOT program – XY or Horseshoe

The XP Deus XY screen nails big iron

The XP Deus Hot program
Comparing the XY and the Horseshoe graphics.

The XP Deus metal detector | version 4.x has seen the introduction of the new XY graphic screen, I have been asked many times what is the best one to use.
To be perfectly honest I don’t think there is a solid answer because they both offer their own individuality.

XY Graphic

The XY is a nice simple  “Yes – No” interface which is easy to understand, personally I would have liked some kind of mineralisation bar as this is the only thing I miss having.

The target report is mainly a straight line, which increases in size depending on the intensity of the target, the sensitivity of the line can be adjusted by the user, this is called the zoom feature.
Why would you want to increase the sensitivity of the line.
That’s a question I asked when I first started using the XY, but now it makes a lot of sense, for example : My zoom setting is set at 3, rather than the pre-set 6, this is because I find the audio is far more reliable when deciding to dig deep or small targets, compared to a meter.
In a nutshell I don’t want an inconsistent meter reading to cloud my decision.

So what advantages can the XY screen offer :

Identification of Coke – Hot rock – and large iron, in most cases coke gives a true top bottom reading, hot rock gives a left right reading and large Iron is just plain ugly.


The coke signature is pretty reliable, a top bottom thin line, however my tests on some very thin Gold can also give this reading, so it is up to the user to make the decision to dig or not.

Hot Rock

When using program 10 Goldfield I am regularly bothered by hot rock, the XY screen nails it every time.

Large Iron

Sometimes this gives a good audio and a solid number on the Horseshoe meter, but the XY is pretty accurate with identifying these targets.
most coins and pure targets are represented by a pure line, with no deviation, in many cases shotgun shells give a slightly disrupted line, but this should never be taken as gospel.

The Horseshoe graphic

There is a lot more information on this screen, including a bigger target ID, but in many cases too much information can be a bad thing, take for example the ground phase reading and the adjusted ground balance numbers, this encourages people to chase the numbers when in most cases they are random numbers.
More is explained in this video.

As said earlier, the mineralisation bar is, to me very important as it is a good indication of the ground strength, in many cases here in the UK a high ground level can be a sign of habitation.

The horseshoe meter works on a similar principle to the XY, left for ferrous, right for non-ferrous, I say similar because somewhere deep within things are different.
When using the HOT program the XY gives a true left right reading, where as using the HOT program with the horseshoe every target (Ferrous or non-ferrous) will give a positive Non ferrous reading.
This is because program number 9 HOT uses an open discrimination, if you wanted to see a ferrous reading on iron, you will need to introduce some discrimination.
I personally feel program 9 HOT compliments the XY screen.

Here is a video demonstrating the 2 screens using the HOT program I hope it is of some interest.

XP Deus 4.1 – Users review

Since the launch of the latest XP Deus version 4.1 firmware update, we have noticed a bit of confusion and panic among the Deus users, so we thought it may help others to do a short review of the update, and try to quash rumours and clarify the overall situation.

The V4.1 has been available from some time as a Beta version for testers, now it is presented and ready for download in its full form at .

We will start our review by facing one of the most publicised issues related to the V.4.1, more exactly the technical problems that occur during the update.

First of all, the user must be aware that the update can only be done only through a PC/Windows operated unit (at this moment there is no interface for the Mac/OSX) and we all know how many problems can be related to a Windows operating system… We’ve noticed many users complaining that everything would freeze during the update, either the Deus RC screen or the PC update screen page (or even both). One simple solution in order to have everything running as it should, would be to stop your PC Firewall / antivirus programs before starting the update (turn off firewall & antivirus > reboot your computer > download the V4.1 > install it > everything should be just fine).
You will need a good internet connection during the update.
The new protocol asks you to make sure the items being updated are on charge, if you do not have enough charging plugs, simply put each item on charge when it is time to update them, also if you have an HF coil, this will not show up on the update.
Do not turn your headphones on until you are asked to do so, this will be after the coils have updated.

As for the previous updates, even with the V4.1 you will have the possibility to work exactly like in earlier versions: If you wish you can create your own custom program from one of the factory programs, I prefer to use the ”Hot Program”as a platform as it is built on the V3.2 filters, while the ”Deep Program” uses V2 filters. Updating from 3.2 to 4.x I can instantly see you have not lost anything, but you just have gained more options, and that is one of the most powerful Deus characteristics…Options!

Let’s enter a more detailed view on the V4.1…what’s new about it, what is the point of updating your system in the first place.

We must start by saying do not expect anything totally new or miraculous.
After we tested it, we concluded that the V.4.1 is more like a ”finesse” update,  one oriented to the fine tuning of some already present features.  The V4.1 does not change any of the discrimination or GB parameters, but introduces few more options related to them.

Deus version 4.1 improvements

We must say that we have spotted some real improvements related to the wireless connection to the coil. Some members of our team use the Deus lite setup (having the WS4 headphones instead of the RC control box) and had in the past few issues with the connectivity to the coil. Now everything looks fine and very stable, without having any more problems related to the pairing of the WS4 headphones to the coil.
The connectivity speed of the MI-6 pointer to the Deus is also improved, even though we did not have any problems with it before, now it seems faster.

Probably the biggest V4.1 new feature would be the additional options related to the GB/Ground Balance menu. By entering the Ground Balance Expert menu, you will be able to tune the Deus in order to track and read different kinds of soils, depending on their intensity. If you search a low mineralized area using a low ground sensitivity (1 to 5), the Deus won’t track it and won’t display the ground values, operating on the default recommended level of 88. If you go for higher ground sensitivity (6 to10) the tracking mode will pop even in low mineralized soils.

In order to keep everything running smooth, it would be better to have the ”Ground Sensitivity” kept at lower levels (1 to 5).
Here is a detailed article on the Ground sensitivity and the Deus ground balance.


At this moment in time the GoDetect phone app is still under construction, I talked with XP and they assure me something really good is in the pipeline, so I am happy to wait for the finished product. The GoDetect software is in your RC and will not require another update when released. It’s the phone side which is being worked on.

Our thoughts

Our overall experience with the V4.1 was a positive one; we were somehow prepared to face a less stable platform, but it wasn’t so. The V4.1 is very stable, we have not experienced any disconnection of the RC from the coil, no false readings or any sort of glitches.

Watching social media we have noticed an overall fear related to a possible loss of depth while using the V4.1.  We noted all the questions or frustrations that we saw online, on several pages and forums, so we decided to run some tests with the new update and the HF elliptical coil.

Our results were pretty much the same as the ones obtained with the V4, but on deeper targets the V4.1 signal appeared to be more stable and clear. Also testing V4.1 gave us a 1-3cm depth advantage on some targets (especially small silver coins or fragments).

Our conclusion is that the V4.1 won’t lose you depth, so do not panic about that, in fact we found just the opposite.
You have to think, are these scare stories about the Deus updates released by internet trolls.
The XP web site and the XP Classroom have a wealth of help and information available to everyone at all levels – What other manufacturer offers this amount of on-line support, I can tell you NONE !

So yes version 4.1 is a real winner for us guys so follow the instructions and update your Deus.

Get out into the field, follow your dreams and enjoy the Deus experience.

We wish you all the very best.

Michele and the RMA Deus test team.

XP Deus ground balance talk

The XP Deus ground balance

The Deus operates what I describe as a true ground balance and can require a little more understanding compared to many other machines on today’s market, just because it is there does not mean you have to get involved with it, as I will try to explain in this article.
Without ground balance – or ground cancel, the detector will see the ground beneath your feet as a target.
Ground balance is a form of rejecting the ground whilst still having the ability to detect ferrous and non-ferrous targets, very much like rejecting Iron and only hearing non-ferrous targets.
Typical ground conditions around the world are either conductive or magnetic, sometimes a combination of the two.
Take for example an average field in the UK, it is wet, this makes the ground conductive, then introduce years of cattle waste or modern fertilisers and the ground matrix is a mix of different minerals that can change from area to area.
Another example is magnetic iron sands (“Black Sand”), salt, and high concentrations of other minerals in the water will call for a different range of adjustments.
This is a difficult challenge for any VLF metal detector, sometimes it is impossible to get an accurate ground balance, so a compromise has to be the best solution.
This is why XP offer factory pre-set ground balance settings, so you don’t have to worry about complicated adjustments.

Do I need to ground balance my Deus

The answer is NO the user does not always need to perform this procedure, because XP have taken care of most of the work within the software, the factory pre-sets are more than adequate for 99% of most UK inland searching. Notice I said the UK, as I know some overseas soil very often require extra adjustments for optimum performance.
The operator can adjust their ground balance if they wish to change the characteristics of the Deus in order to suit their searching environment, or to find specific targets.
However they must also bear in mind there may be negative consequences if the ground balance is incorrectly adjusted.
Chasing random “on screen” ground numbers can be very counter productive.

Top Tip : Only adjust something if it requires adjusting – never adjust it just because you can.

Ground numbers and consistency – how they are generated

This is possibly the easiest way to explain how the ground number are generated:
Let’s take the Deus and wave a coin in front of the coil, when the coin is close, the “Target ID” meter readings are solid and reliable, move the coin far away and the meter readings become less consistent.
The same applies to the “Ground” readings, a solid ground echo is indicated by a high mineralisation bar, the numbers can be trusted. A low mineralisation bar indicates a weak ground echo so the numbers will be inconsistent and in many cases inaccurate, just like the target ID we have just talked about.

Version 4.1 Ground sensitivity (New feature)

Version 4.1 has a Ground Sensitivity feature – GROUND SENS.
This allows the operator to adjust how strong the ground signal needs to be before :
A: The ground meter gives a numerical display.
B: The Deus starts to track the ground.

For example lower numbers will require a strong ground signal to activate the ground reading.
Highly mineralised soils typically give the strongest ground signals, indicated by a high mineralisation bar.

Figure 1 : Mineralisation bar

If a strong ground signal is not received by the Deus the numerical ground display now will show – – and the ground balance will default to 88.
This is also the case if the coil is motionless for a short time, once the coil is in motion again the ground numbers will resume, providing there is a strong enough signal for your chosen ground sensitivity setting.

*Note: Earlier Deus software versions had a fixed ground sensitivity of around 10.

What is the best ground sensitivity setting.

In most cases somewhere between 4 and 6 will work well – Once again I am referring to the UK here.

How do I set the ground sensitivity.

You can be in either tracking or manual GB mode.
Swing the coil over the ground and detect normally, we do not recommend pumping as this can give an over powered reading.
As you detect watch the numerical ground display and adjust it accordingly, I prefer to see a constant – – reading with an occasional number, but you may want to see constant numbers.
There is no exact setting as this is a user PRO adjustment, time should be taken to learn this feature.
It is not recommended to set your Ground sensitivity to high because you will see erratic numbers appear as the machine is trying to report or track to every slight change, and as mentioned earlier, these could be inaccurate numbers.

Tracking mode + Ground Sensitivity working together.

You can now use ground sensitivity to tell the machine when to track.
For example: If you set the ground sensitivity so the ground numbers only display when you are detecting over mineralised ground, then it will only track at this time. If it is not tracking, the ground balance will default to 88 and show – – above.

Why default to 88 if there is no ground signal.

88-90 is the best all round setting for most UK inland soils, it will eliminate most magnetic rocks and minerals. This is my preferred setting.
Let’s imagine you are searching on mild ground in tracking mode and your ground sensitivity is set only track over areas of higher mineral, your ground display will possibly show – – most of the time.
As you pass over an area containing “Heavier” ground your machine will track accordingly and display the relevant number. Because most of your ground is milder it will not be strong enough to activate your tracking back to the lower (normal) setting, so your machine will remain at the higher level after you have moved away from the difficult area, resulting in an inaccurate ground balance.

Figure 3 : Default ground balance – – No ground signal and a default of 88

As a safeguard the machine will default to 88 until a further mineralised patch of ground activates the tracking again. Once again this depends on how you have set the ground sensitivity.
Tracking is best suited for ground with gradual changes in mineralisation. It is not recommended for ground with lots of iron contamination and fast ground changes.

Can using a lower ground balance give more depth.

Sure in many cases this can increase depth, but you must understand there will always be a trade-off. For example, lower GB settings may introduce unwanted signals from some magnetic rocks, ceramics and also make the coil “oversensitive”, especially if searching wet (conductive) ground.
A tap on a root or even stubble will give a false signal if the GB setting is too low, false signals will mask small targets and once again will be counter productive.
Remember depth is not the holy grail of metal detecting.

So in a nutshell a lower GB will give more depth, just like raising your sensitivity to 99 but you would not want to search like that would you!
I think you are getting the picture now.

Can I raise my ground balance to 99

Now we are getting into the realms of witchcraft, raising the ground balance can be just as detrimental as lowering it. Levels of 99 may shift very highly conductive targets over to the reject range. For example: A large Silver plate may give the iron tone if the GB is set too high.

When I lower my ground balance I get a good signal from magnetic rocks, can they be eliminated

In many situations magnetic rocks can very often be eliminated using the ground notch feature.
Remember magnetic rocks also known as Hot Rock are rejected by ground balance, not to be confused with Coke which is rejected by the discrimination.

Ground notch

Introducing Ground Notch.
Ground notch is exactly what it says, the operator can assign a certain ground range to be ignored, in this case of the graphic below, Hot Rock is rejected by the ground notch. There are not multiple “thresholds” to choose from like we see under the discrimination notch menu, although Ground notch works on the same principle…It notches out a particular ground range that may contain unwanted targets.

As you can see by the graphic below hot rock registers at 88, the ground notch has eliminated 83-88. The overall ground rejection is 60 – 76, you can see 77 – 82 are still accepted, 90 is the maximum range for ground notch.
Remember this is the ground range, not the discrimination range.

The factory pre-set ground balance runs from 60 to 95, at 90 all of your unwanted troublesome ground and hot rocks are eliminated, even slight changes from 90 to 88 will be enough to make your machine a little more “edgy” if required.

Why does the beach setting require a different ground balance

This is because the wet sand has a different mineral range to inland, so a different rejection range is required, from 0 –  30.
As you can see, typically wet sand falls around 25, it is advisable to pay attention to your sensitivity setting when searching wet sand, very often it will require a lower setting to maintain a smooth operation.

I want to hear hot rock and Ceramics because it gives me information about my site but lowering the GB gives them a high tone, is it possible to make them a low tone

Yes this is now possible with version 4X software and the HOT program, or any factory program using Full Tone audio.
The discrimination range now falls below 0, in fact it can be lowered to -6.4, this “sub-zero” range will accept targets such as hot rock and ceramics as a low tone, if you want to eliminate the feedback, simply turn your discrimination up from -6.4 to -2, then you will only get feedback from ferrous and non-ferrous targets.
This is where ground balance and discrimination cross paths.

…………………….But that’s another article for another day.

Does Goldfield program 10 use the same ground balance

Goldfield uses a slightly different filtering system and works best with an exact ground balance in order to gain the optimum performance.
To start with you will need to ground balance on a clean area of soil, start by slowly raising and lowering the coil up and down and listen to the feedback, then as the coil approaches the ground press the PIN POINT button once, you should hear the feedback drop. This indicates a correct ground balance and your 2 sets of ground numbers should be the same.
If there is an inconsistency, repeat the procedure again, sometimes it may be necessary to lower the sensitivity to obtain a smooth performance.
Manual – pumping – beach and tracking options can be used in the Goldfield mode.
As mentioned earlier – If your ground balance range falls below certain conductive rocks, you will hear a signal from them, they sound almost negative as the coil passes over them. With a little practice you will learn to ignore them.
The XP screen is a great addition to the Goldfield program as it gives a lot of useful target information, such as a flat left right line for Hot Rocks.

I hope this gives you an insight into how versatile the XP Deus can be, simple for those who want to just switch on and go, and for those who like to change, the machine it can be a complex as you wish.

Final tip :

Ground conditions change all over the world, if you are looking for maximum depth, remember ground conditions will in most cases dictate the performance of your machine, sometimes it does not pay to over think things and convince yourself you have the wrong settings, when you are at the mercy of the soil conditions..
An erratic machine may miss small targets, a smooth running machine with less power may be a better option, this is why the Sifter program is a very popular choice.
Most importantly have fun and enjoy your Deus.
