Hello to all, I am currently using a goldbug 2. On the creek in the Yuba River drainage where I am using it, there is a lot of exposed bedrock, or alternating gravel and bedrock. I am finding that the bedrock ground balances far different from the gravels. This is a bit of a problem for me, since when I ground balance to the bedrock, any of the gravel sounds off loudly. When I ground balance to the gravels, then pass the coil over bedrock, the detector goes null, or quiet. Seems this contrast is giving me a lot of false positive reads. I have found a fair amount of flakes and small pickers, but feel that I may be missing good targets, since the bedrock and gravels ground balance so so differently. Any suggestions on how to deal with this would be much appreciated.
