I setup a program to run single frequency 22k with notches for nickels and zinc coins and above. So the only targets that should sound off would be the nickel zone and any coins from zinc penny and up. All the other TID numbers were rejected. I took the normalization off but I get no sound on the accepted targets. Almost like it is seeing the correct target ID and the target is showing up in the accepted area but its almost like its confused. With normalization off is this normal?
