What is up with this?

My brother and I were hunting a local park this past weekend, for the most part we hunt in sight of each other. He was running an F5 and was running a F75 and both of us had on the 11

It's possible some type mineral was in the ground area you guys were detecting... It may have been on the nickel and as you handled it the conductor rubbed off..

...................or you didn't recheck your hole again and a quarter was in there..........................

Every once in a while something like that happens that makes a guy wonder...I hit a deep dime signal yesterday, maybe 5" deep, so I get it out and its a Canadian dime and it looks like silver, so I toss it on the ground to sweep to know for sure, and it doesnt make but an iron tone...unless I tossed it on top of some iron, which I dont think happened...its a 1977 date...every once in a while a N comes in like a Q...experienced that last year on a canadian nickel...stuff like this doesnt happen often, but it is a puzzlement when it does. Things can sometimes sound different down in the dirt I figured and left it at that..metal is interesting!

Elton,

You may be right, I am going back over there Saturday, I think I will try to find that hole and check it again. I remember taking a coin out of that hole but I can't remember if it was a quarter, dime or penny, I found a few of all. I also can't remember checking the hole without the nickel in it. I can blame my brother he got me side tracked.

I've had simular situations crop up like that from time to time and on two recent occasions something like a screw had rusted out and all that was left was a rusty looking spot in the dirt. I've even dug rust spots on occasion that sounded dang good. ????? HH jim tn

I've learned that around here to sweep the target again after I start digging, when the ground is wet.
The iron in the soil seems to create a conductive signal when wet that can sound like a coin. But once you stab it, the signal change to iron. Happens quite a bit in the sand volleyball courts.

You could be right, now if I can just find that hole.

I guess we will never know, I was back over there yesterday and couldn't find the hole I was working out of.

My park are must be getting pretty clean, there was 2 of us hunting and at the end of day we only had 12 coins each.

Another thought on the subject. Or maybe it's already been said.

More than once I have retrieved a good target that any sane individual would have passed on. Then out of habit I'll re-sweep the same spot while in the pinpoint mode. While doing so I'll often find that the ground balance in the immediate area surrounding the iffy target is much different than the sites overall GB. I would think the opposite effect could come into play.
