Where did my signal go?

I was hunting with my vequero and had a pretty good signal ,thought it was a coin or pop tab.
ended up with about a 18in dia hole about a foot deep because it seemed as if the object was
moving. Then my signal disappeared ,I checked in all metal ,checked my ground balance everything
I could think of .It was gone!!!!! couldn't find anything in the huge mound of dirt I had either.I talked
to a friend with a tajon and it had happened to him also one time. Any Ideas?
 
I think that has happened to about every detectorist.

There are some things that may happen during this process.

The object may have been very thin and ended up on edge, seeming to disappear.

Once the dirt is disturbed it changes the ground matrix. A rock or clod that was more or less invisible to the metal detector while in an undisturbed state can mask the object once it's in a pile. The object could have easily been in the pile of dirt you dug from the hole. And it could continue to mask the target even when placed back in the hole.

A nail or hot rock or something could gotten between the coil and the target. Again masking the target.

The object could have rolled off when it was dug and be a foot or so from the pile of dirt.

It could have been a rusty nail that had a large signal because of all the rust in the ground around it. Once the ironized ground is disturbed the signal was reduced. A small nail can escape detection by a Vaquero.

The sensativity being set too high can cause semilar problems. There are other things that can happen and I'm not experienced to know them all. And it has happened to me with different brands of detectors.

Don't worry your not going crazy. With experience you will learn to deal with such problems more efficiently.


Good luck,
 
Tabdog nailed it. Last Saturday a friend who has been detecting for 18 years and I were detecting the old football field here in town that was used by the highschool from 1915 through 1958. It's still used as a playground for the middle school and neighborhood kids so there are always a few new coins there, plus the possibility of older coins. The friend yelled for me to come over to where he had been digging for several minutes. He had a hole about 8 inches in diameter and a foot deep and asked me to see if I could get a signal in the hole or in the dirt he had dug out. There was no signal, he said he had initially got a strong signal that ID'ed as a penny but it had got weaker after he took a plug out and disappeared completely after taking out a couple more inches of dirt. I scraped the sides of the hole with my trowel, pulled the dirt out of the hole and there it was. A 2002 penny that still had some shine to it. He had managed to turn it on edge and as he dug deeper it kept falling down the side of the hole. It happens to all of us:).
 
This is a good example of why I always use a pinpointer.
