Ground balance question

Post by Ollie K »

Hi everyone, I went out today with my new deus today and used the standard GMP programme. The ground balance is set at the default number 90, however I noticed that at some stages the other reading fluctuated from 90 to as low as 76. I'm going back tomorrow so do I need to adjust the gb setting, and if so which should I use? The field isn't very trashy (apart from a fair few drinks cans), and according to the bar, very little mineralisation. Cheers, Ollie ::g

If I remember it correctly from the last time I read it, the top number is the actual balance reading from the ground and will change as you move around your site. The bottom number is what you either set it too if in manual mode or what the Deus sets it too in tracking mode. If it's in tracking mode the lower number should change to somewhere near the top number based upon an average of recent readings.

If you are in Beach setting , it's different again as as is pumping GB mode.

Thanks Maxim. I had a go at setting it to tracking earlier but couldn't see a lot through my DIY plastic bag remote cover in today's crazy rain. sw; I wasn't sure what to do when I pressed into expert. I'll look in the manual tomorrow but is t pretty straight forward? Cheers ::g

I use tracking most of the time too. Occasionally you might find it goes a bit chattery and chirpy and if you look at the top and bottom GB numbers they may be quite low. I find it does this sometimes if it's been laid down or sitting coil down over deep iron. If it does this, just move it away, give it about 10 seconds, and it should go back to where it was. Some areas on my permission really do go very low genuinely, so moving won't change it. In this case just go steady so you don't miss anything hiding in the mineralised ground, till you get off that patch.

Hi tend to use Tracking the ground i search is very mainlined.If you are on a habitation site with lots of iron i would not use tracking.The factory setting will work on most ground the higher the scale grays out the more you need to adjust the gb if no graying you can run ok in the factory setting. ::g

Dont go to low with the GB !!! The Deus can in Very trashy areas with the tracking mode go to low..
90 is to high but 76 could easy be to low (noisy If its to low).
If you can swing your coil over a hole were the target is in the hole, and you can get same good signal (allmust) like before you did start dig, your are in Balance..
Manual GB + 1 or 2 over the average at that field in trashy areas is a safe way to search with the Deus. Thats my way to do it.

Another way to do it would be after the initial start up give the coil half a dozen or so pumps up and down , Check to see what the ground says and adjust it to that number , anywhere within around 6 of that number is good ::g so if it is showing 76 and you have it set on low 80s then you should be alright ::g

after speaking to alain from xp and adam both of them seem to run the gb in manual and keep it just below what the machine is telling you .it does give you a slight edge over those using tracking as it will give you a little bit more depth but you have to keep an eye on it and have to change it .when it gets in the low 70's it can get a bit noisy .as Donna said it has about a 10 second delay before changing . normally tracking is good but if you want those slightly deeper targets get on manual

Thanks mate, think I'll go with tracking as the ground seems to vary quite a lot. I've just looked up tracking in the manual but can you just clarify - do I just scroll down to tracking and it will automatically select it then return to the 'home' screen or do I have to select tracking somehow? Sorry if this is a stupid question only I don't want to get out there and then not be able to do it ,':( All the best ::g

Yep, just scroll down to tracking and once its highlighted it automatically selects it. Then return to the 'home' screen.
