Let’s have a quick talk about ground balance I know this subject confuses a lot of people and to be honest with you I can understand why, there's so much talk on social media about lowering the ground balance and how it makes the machine perform better etc etc there's a few tips I just want to run by you and just give you a better idea of what ground balance is all about Lots of people say lowering the ground balance will give you more depth and this is absolutely true it will give you more depth but what's the trade-off …youre going to start hearing lots of noise from hot rocks and the ground itself so you have got to try and find a happy medium and in most cases between 88 and 90 is going to be absolutely perfect. Ground balance isn't the be-all and end-all to metal detecting it’s only a part of it, it's a feature there within your detector and it's something you don't have to use unless
called upon. Different parts of the world determine different ground balance settings for example here in the UK we don't have a massive problem with hot ground, ok there's small patches there’s small areas about the country but in general we don't get a very strong signal from the ground, the biggest problem we have in a lot of places in the UK is iron contamination and that requires a completely different set of adjustments. So ground balance what's it all about. Your machine sees the ground as a target just like it will see a coin or piece of jewellery What we need to do is eliminate the ground from the target range so we don't hear it and that's why we ground balance to eliminate the ground is as simple as that Now the ground changes all over the world for example gold bearing areas tend to have a lot of hot rocks and the ground is very very hot so a critical ground balance is essential.
How do we know if our ground is hot, well that's really really simple we look at the right hand bar on the screen it's called the mineralization bar and when sweeping take a look at it. If the bar is quite high that indicates you've got hot ground and there may be an advantage to ground balancing. If you haven't got a bar or perhaps one or two bar, it is telling you that your ground is not very hot and this means there's not strong enough signal coming from the ground to warrant any problems. Let’s take a typical coin, and pass it across your search coil quite close and you will get a reliable target ID meter reading, now as your move that coin further away the numbers will become less reliable because the signal is weaker and this is exactly what's happening to the ground if you've got weak ground your target ID numbers for the ground range will be unreliable and will chuck up random numbers, if you're in tracking mode your machine will
track to these random numbers and very often it will track too low so you'll get lots of false signals from the ground or hot rock.. Hot rock Here we go let's put the hot rock on the ground with using Deus fast and as we sweep Im getting 5 bars on a mineralization bar, now if you pump it, quite often you get a stronger reading but just to mimic real detecting I’m sweeping it, obviously over a clean piece of soil. So here’s a hot rock, I'm going to put it on the floor and listen to see what happens on the standard Deus fast program…..Absolutely nothing! we wouldn't even know that hot rock is there, now if I go into manual and start lowering the ground balance 86… 84 can you
hear that hot rock start to come in… 82 we've introduced the hot Rock by lowering the ground balance and it's a high tone. What happens if we go even lower just for argument sake 75 we've made it stronger again and backup to 90 the factory default 90, 90....Gone ! I've just demonstrated the hot rock let me lower the ground balance again and show you the shake value. Now I'm on 74 just for argument sake…. So can you imagine when you hit against
stubble or rocks this is going to drive you mad, so if you're going to use a low ground balance you need to make sure that there's no obstacles your coil is going to knock on because by lowering the ground balance…. in a nutshell you're making a search coil too hot. You may not even know you've got hot rock in your ground but trust me if you lower the ground balance below the hot rock level you certainly will start hearing it. The ground notch feature it's exactly what it says, if you want to run a lower Ground balance and you're pestered by hot rocks all you do then is notch out hot rocks from the ground range. But bear in mind for example if you run the ground balance at 70 and you lower the ground notch to 71 so from 70 above it's all greyed out it's exactly the same as running ground balance of factory pre-set 90 so there's really no advantages to using a long line of ground
notch just use enough ground notch to eliminate your particular target. Ground balance and discrimination are two separate things but sometimes their paths cross. Let’s take the hot program number 9 for example it uses a sub Zero discrimination and goes down to - 6.4, and using - 6.4 will accept the ground, but unlike the test earlier with the hot rock, the hot rock gave a high tone a positive tone, now if using the minus 6.4 discrimination you introduce the hot rocks and the ground as a low tone. Program number 9 the hot program when using a sub Zero discrimination - 6.4…..High tone for a good target low tone for a bad target let's try it over the hot rock now. Can you hear it, its coming up as an iron tone, and as you can see the XY screen is
straight across indicating the ground. So how do I get rid of that using the hot program? I just make a simple adjustment to the discrimination …. - 5.8 and it is completely gone So if you want to eliminate the ground and hot rocks using the sub Zero discrimination just raise it up a bit to - 5 - 4 something like that and you'll still pick up the iron and the good targets So that's the beauty of the sub Zero discrimination on the full-tone program, at - 6.4 you can hear all the ground so that you've got a good idea of what's under your feet, if you don't want to hear the ground and hot rocks and things like that just keep raising it until you've eliminated the things you don't want to hear it's a simple as that. When you adjust your ground balance, you will notice three little dots under the number they are just fine increments 1 2 and 3 so you can get a really fine adjustment on your
ground balance settings. Tracking Now that's ok to use if you've got gradual ground changes it's not worth using tracking on an iron infested site, the machine will just get confused, and also remember if you haven't got a strong enough ground signal you're tracking will track two random numbers so you never know if it's right or not, it's always best to use a fixed setting and adjust it only if needed. So by adjusting the ground sensitivity you can make your machine more or less sensitive to the ground minerals and that's the simple as that, earlier Deus models had a very high ground sensitivity setting as standard, so you got lots of random numbers but with the latest versions of the Deus the factory pre-set ground setting level only gives you a numbers when it sees that the ground is hot enough to perhaps make a decision on ground balance.
If not you will just see the icon dash dash and it will factory reset to a ground balance of 88 so you don't have to do nothing. Once again if you stop swinging, you'll see the numbers stop and dash dash will appear and it will default to 88 and once you start swinging again if you go over a patch of slightly higher ground it will then show the numbers or indeed track to those numbers, if you've got tracking enabled. So the ground sensitivity is a really good feature providing you use it with caution. Why see numbers if you haven't got a strong enough ground Echo well that's it for my very quick talk about the XP Deus ground balance I could go on for hours about this subject but I just wanted to keep it brief and simple. Thanks for watching if indeed you still are ! and I'll see you on another Skill School video.
