Squeezing Bit More Depth Out Of The AT Pro

[kac]

I stumbled across a post on another forum about the auto ground balance on the AT Pro and how it is not as close to the ground mineralization as it could be. The poster suggested auto ground balancing then switching to manual ground balance and dropping it by 5 clicks.

I tried it with a couple targets on the ground, silver dime, gold earing and small white gold earing and yup gained about 2" on the gold and easy 3" on the dime. Though the targets were on the ground and not buried I believe the gain will be a bit less but the vdi numbers will be more accurate. I also tested 10 clicks down but that may be too close the grounds mineralization and the machine may start falsings. I had done this before at the beach where auto gb doesn't work that well. In wet sand the Auto Gb would set the machine around 12-14 and running the machine at 8 or gave it a bit more punch and actually ran quieter. I just never tried that on land as I assumed when the machine was quiet it was good to go.

I'm sure many of you already knew this but thought I would toss it out anyways.
