Hunting my old school

[chip12977]

So I've been hunting my old school that was built in 1936, I've found a lot of clad and I found a 1911 V-nickel, so I know there is some old stuff in the ground, problem is my detector is constantly beeping and going crazy and in turn makes hunting a slow and frustrating process.

So how do I quiet down my detector without buying a smaller coil?

First off I have a v3I and I'm using the stock coin and jewelry program, I have tried to ground balance, I've tried to offset the frequency with no change, I even pulled the trigger and lifted the coil off the ground and turned 360° to see if there was electrical interference, which there was none. When I lift my coil the thing beeps until almost waist high (only does this at the school)
So anyone with a v3i care to take a guess as to what else I can try

Perhaps it's something in the ground there? Or in the air there? (radio tower or something emitting, etc...) So for example, if you were to go across the street from that same school, to sample on another plot of ground, does it do the same thing? How about across town?

Try turning your sens. all the way down. If that quiets it down (no falsing), then slowly start turning the sens. up, to where you just start to get that interference.

I went there again this morning and noticed that every coin I pulled out had a rust color, but the soil is black, very soft, my digging tool goes in like a hot knife through butter

Funny, but I hunted and area where an old school was torn down. The playing field is still there. It was the first time I ever went out and found nothing. I use the white's MXT Pro. It was giving me false signals all over the place. There were tons of cans and pull tabs. It was telling me quarters and dimes? I tried everything I could think of. Just could not detect there. Went from there to a park and found a few coins, just clad, but that place has been hunted to death so did not expect to find even that. If you figure this out let me know.

I agree with Tom of CA on his advice. It has to be some kind of EMI field or transmission. Turn sens way down and try to find very shallow items if you can
