While hunting in a friends yard, I noticed a strange interference on my MXT in coin mode, narrowed it down to about 50 meters away underground from what I can tell around 3 to 5 feet. There are no buried power lines in the entire area, and all cable tv is strung overhead. Has anyone ever heard of or heard this before? I switched modes but it was the worst in coin mode. (It was present in all modes.) Settings as follows.....
Gain-0 Disc-9 Threshold-1, Ground set to ground. Yet I STILL heard this noise. Even after dumping all the controls, I could hold my machine stationary above this "target" and watch the different types metal id bounce around in a pattern, is sounded like it would repeat around 20-30 times then change to a different pattern. Not a high mineral soil area, just standard clay/dirt for Wisconsin. A friend suggested an underground rock formation that was reflecting my own field, but from 50 yards away? Point the coil up in the air and it's still present, gradually to the ground and it gets louder. I am clueless and in the dark, now my friend thinks he has a UFO on his lotline. I told him to grant them an easement, but he didn't get it. Oh well, any thoughts? Thanks much in advance.
HH as always,
