On my pocket probe got some questions from some guys on the depth and volume, OK, mine air tests a new dime at 3 to 3 1/4 in,wherever i have the freq set, but on stuff in the ground seems much deeper(frozen ground) really can't check it at all .
The volume is not very high=is this normal? it seems to work well, on larger objects it really gets out there, seems OK, this normal??
