since i was getting an 8" buried dime whith the coil lifted 3" off the ground i decided to put a dime at 10" deep in ground and i was very presise about it and it came thru loud and clear in all metal but in disq i maybe got a tick one way hit and miss but very clear in all metal that is contrary to what the manuel says the manuel says its deeper in disq I do not find that to be so
