Ghost Signal

[damatman88]

I have many hours on my Eq 800 with a lot of success in the last couple of years. One thing that continues to stump me sometimes when land hunting is this: I will get a solid repeatable signal in the 20s to 30s. The signal pinpoints as a tight, smallish target. I dig down very deep (15+ inches) and never able to find anything with my pinpointer. The signal remains the same when I swing over it though. Maybe a piece of big, deep iron? Anyone else have this experience?

This is odd… have you tried lifting the coil up some while swinging over the target to see if it disappears…. I use that method sometimes to gauge the size of targets
I have had what seems like small targets too sometimes, but I usually am able to determine what it is… sometimes it is a rod or small piece of pipe vertical in the ground.

Do circle your pinpointer around the sides of the hole in a downward spiral motion? I have been fooled more than once with the target in the sidewall. Particularly when the coin is on edge and when they are I've noticed the signal is stronger off the edge of the coil. Just something to think about. Good luck. Mark

Same occasional problem with the F75. There is an object in a local sports field that hits a tight 89-90 (large silver like a dollar) and registers 5” deep from 360 degree signal. Been as far as pushing 10” with strong pinpointer response but nothing. Went back the other day with no one around and removed my plug. Still getting same responses so carefully checked the sides, all equal in response. Dug another 5” and still reacting like I should be touching it. Reduced sensitivity on the Garrett carrot to low and it disappeared but detector said 5” down and dead center in my hole. Lifted coil about 4” off the ground and signal gone.
So either some cylindrical iron piece or a stack of silver dollars a foot high, no clue but without further authorization to excavate its a guessing game (or a 2am mad dash).
Other wise large iron usually rings out super high for me, like 98-99.

Maybe a half dollar on edge off to the side of the hole. On the Nox in particular, I've had targets hit off the edge of the coil and if I'm not paying close attention or don't pin point the target it won't be under the center of the coil. HH jim tn

Maybe someone buried an opposing teams solid silver trophy.
Been known to happen.
Otherwise you may have found that missing Studebaker ...
Kidding aside.
Probably some kind of drain or plumbing.
Found my own waterline once.
Ain't digging that deep ever again.

Gotta be either a huge gold ingot or a car wheel.

Big and deep would be my bet. As fwcrawford suggested, raise your coil pretty high off the ground and give it a few swings. If it stays loud and same number, it ain't a coin or small target.

I agree with the big deep target, it has happened to me on several outings. Most of the time its very rusty iron . I don't like to abandon good signals , but I have had to walk away from some of them. always leaves me wondering what it was !!

My guess sidewall... go in with handheld pointer dig along side wall...
