As some of you have read I am searching for info on how to change the ground balance on my Fisher F2. It is working good but I was thinking that it would get better depth if the ground balance wasn't set so positive for my ground. Today was the 1st. day detecting in wood chips - I got a hit regisitered 7 or 8 inches deep on the display and sure enough a coin was at about 8 inches deep. Dug several at this depth. I am getting less than 6 inches in the ground. So having a ground balance that is not so positive really increased my depth. Now bring on them schematics!!! I am in total belief that being able to adjust the g.b. on the F2 would make a good detector a great detector. Steve.

I was right (ground balance)

No, I am saying that if I could manually adjust the ground balance to neutral or a hair positive I would gain more depth. As it came from the factory it is way too positive for my ground. As you probably know - if you lower the coil to the ground with the pinpoint button pushed in (all metal mode) and if the detector sounds off close to the ground it is at a positive setting & if you lower the coil to the ground and if it sounds off on the way back up it is negative set. What is best best is a neutral setting (no change on the down or up movement). I am not sure but think the F2 has an internal adjustment to change the ground balance but Fisher/First Texas won't tell me anything about it. Being unfamiler with the insides of Fisher detectors I am not going to try to open up the F2 and search for the right pot./trimmer. If it was a Tesoro I wouldn't think twice about doing it.
