Hi everyone, I am trying to find a cache of coins but unfortunately the grounds are very mineralized with tons of hot rocks!! I bought a Detech SSP 5100 Pi machine and it works great unfortunately I am dealing with high grass, no I can't mow it down because of the location. I'm still learning the machine but trying to find other options, I currently own a Whites TDI and would anyone have a program that they can share to help me cut out the hot rocks? I'm still trying to learn and figure out the machine but need like a starting point where I can set it and then make small adjustments. I need it to be in an all metal mode but NOT pick up the hot rocks. Any help will be much appreciated! Has anyone used the TDI for cache hunting? Thanks...
