Another Newbie Question

[flyin-lowe]

I still have less then ten hours with my F2 but feel I am learning a lot. One thing I have had happen that I can't explain and would like some help understanding. I am always discriminating out iron and then running at 100% sensitivity. I am also digging most all targets that I get a repeatable signal on just for the learning experience. Now to the problem. Probably 3 or 4 times since I have had my F2 I will get a target that bounces back and fourth between say tab and foil, tab and foil. I know this is likely trash but in the spirit of learning I will dig. A few times I have done this and dug my plug. Once I dig the plug I sweep over the hole with no response and then over the plug itself with no result. I then put the plug back in the ground and and sweep over it again with nothing. I know there are times that I get a random beep that does not repeat and I ignore it. But why would I get a repeating signal that is likely trash that seems to disapear after I dig. Anybody else experience this or have any idea what is going on. Like I said it has only happened a few times out of I don't know how many targets I have dug.

still held together by ground. Once you break the ground the target is nothing more than dusty pieces. It will not pickup on your machine once it breaks up..

Thanks for the info, I have had some others tell me it could be a very small piece like a buckshot or something even smaller.

I have noticed on most machines running at full sensitivity causes false signals often. The ground minerals can cause this as well. Running a bit lower sensitivity can actually increase the number of finds, due to the fact that when the detector sounds off there is a target for sure under the coil.I have been surprised many times at how much stuff I find when the detector is running at 3/4 or so sensitivity and the depth is very good.
