Hi everyone, I have a question on depth and stability of target numbers. What is the average depth you get with the e-trac before your target id. numbers start getting erratic? I guess what I'm asking is what maximum depth is your machine still giving good solid sound and numbers consistently? One reason I'm asking is I have a 9 inch coin buried in my coin garden that's about 3yrs. old and with the 10x12 coil on I could hardly pick it up at all. I had to crank my sensitivity up toward manual 30 to get it to sound off at all? I run basically the same settings and pattern as Goes4ever does. Thanks and HH.
