Holes That Get Bigger & Bigger

Ever get a signal and then try to dig but the hole gets bigger and bigger w/o ever finding the target? Any info appreciated. Thanks, Joe

i had that problem early on, what i did to solve it was to "de-tune" the detector over the target. i hit the all metal switch or button when the coil over the target area and one of two things happen, if i happen to hit the button righ on top of the target it tunes it out completely, but if i hit it to one side of the target it will bring the target in to a smaller area so that it`s easier to locate. the idea IS to be able to hit the switch when your approching the target, you have to experiment with this a bit but you`ll get the hang of it zman

Yuppers! Happens once in a while. I think a lot depends on the detector; I've only used Minelabs so far, so that'll affect my feelings on it.

One: it's sensitive enough to pick up very small bits of foil (less than 1/8" square); if I hit it with my digger, it either folds up too small to detect or something like that.

Another: sometimes I'll get a hit that's between two pieces of iron; null on both sides of the "target" tells me it's iron... but I dig anyway.

Most often, though, it's because I've moved the target while digging. I hit a dime the other night, just after sunset, that was corroded enough to look just like dirt... couldn't see it, and when I gave the coil a swing over the area, the target moved. As it was in a high trash area, the signals got confusing, but I did finally find it, in a pile of dirt I'd moved.

Good luck, and HH

Dimes will do that to my Bigfoot and Hotshot on the beach.

The only time that has happened to me, when the detector said it was still there, it was a big something. Like a stupid pipe....
That's the only thing I've had that went deeper and wider than any other time.

Being new to this activity, I have my share of growing holes . What drives me nuts is a big hole, hands caked in dirt and now there is no "hit" tone in the large pile, attached plug or hole. Is that what is called a 'hot rock'?
