Out Of Balance Ground Balance?

[tabman]

I read this and I would like to know if any Tesoro owners have tried this with their detectors? Do Tesoro detectors benefit from doing this?.

Lowering the GB will significantly help high conductors such as silver and raising GB will significantly help low conductors such as gold, each detector is different as to how far you can run stability wise from a zero Ground balance point and the soil mineralization will play a part in the equation as well.

Tried it on my Silver umax and Compadre and the only conflict I had was too far one way or the other caused the ground signal to either become mixed in with some of the target signals or not be filtered enough to give a smooth signal. However, I didn't turn it too far one way or another and ended up fairly close to the factory setting.

Over the years many have run their GB a little hot in the interest of better depth and response to targets. I do believe it is on all GB type detectors this can be done with good results.

This was before digital detectors came about and that may be why Tesoros users still have that theory. As most Tesoro's are non digital units.

Yeah, I read something about a little to the positive side will give you a little more depth. When I'm ground balancing, I try to balance as close as possible to neutral, but if there's any uncertainty in balancing, I lean a little to the positive side. For some unknown reason I came to believe that positive is better than negative.

I've often wondered where they set the factory ground balance for the best results overall. More to the positive or more to the negative and why?

This info is based on a Vaquero but should translate to other VLF detectors. Your question piqued my curiosity so I did a test in my coin cemetery today. I found that a slightly negative GB in all metal will null the threshold before it gets louder. This occurred with clad as well as a nickle so its doubtful that a negative GB will improve the detection of gold. I found no significant increase in depth if the threshold was balanced or slightly positive. In disc mode, I have found that a negative balance causes a lot more falsing over targets. If balanced or slightly positive the disc is much more stable. In my pos/neg tests the GB was not severely out of adjustment but I presume that sensitivity will not get any better than when properly calibrated.

Slightly negative balance (moving the knob to the left) will give an extra inch or so on my EuroSabreII. It means moving the knob some 2 - 3 mm, just very slightly. Think of the ground balance as another kind of discrimination. The more you add, the lower the depth. The purpose of GB is to "null out" the soil reaction. In some places the depth is really reduced by the masking effect of the soil. If you go too negative, you get falsing, ie. signals from the minerals in the soil. In some cases, going slightly positive might bring you some more depth as well, but I prefer the negative way Balancing to neutral makes the search easier.

There is one more trick - if you do not use the threshold based all metal, put the threshold on full. That makes some faint signals clearer and you can reach a little deeper as well.
