Ok, here goes.
I'm using the Tejon.
Done some test in my planted garden of US coins ranging from fifty cent piece to pennies. Several coins were buried flat and at 3" deep. On edge coins were also buried about 2" deep. These coins have been in the ground about a year now.
Tried checking each coin with the GB perfect. Noticed if I raised the coil off the ground 4" I would loose the signal on the quarters, dimes and pennies.
Adjusted the GB to full positive and this made the targets loose response with the coil at 4" off the ground.
Then set the GB to full negative and to my surprise all coins hit well with the coil 5" off the ground.
My question is this:
Why would being negative help with target response in my situation?
