Signals seem to disappear.

Hello,
I was hunting a sand volley ball court today and would hear signals showing 4-6 or 6-8" using my ACE 350. As I would start to dig the target, the signal would just disappear. I checked "dug" dirt pile with the pro-pointer and the 350. Happened about 3 times. Also would get a tone as I was swinging, then could not find it again. Sand was moist and dense as it rained two days ago. Any thoughts on what the deal could be?
Thanks!

Sounds like your signal was actually just the ground. When you dug, you disturbed the ground and the signal went away. My beach is surrounded by cliffs with pillow lava. before I got my infinium, I tried my ACE 250 on the beach, same thing as you. Much easier to tell ground signals from actual targets with a PI. Now you have experienced first hand one the many reasons a PI is king on the beach. Though, there was another guy here that used an ACE 250 on the same beaches, he would take the sensitivity down to like 3 and he had terrible form, the pendulum swing, very reckless, and he managed to get gold rings as much as I did. I never understood how he did it. One day I'll have luck like that.

It was probably a remaining piece of rust left over from a rusting piece of iron. When you disturbed the sand, the rust disintegrated to the point where the detector could no longer detect it. Quite common.

Thanks guys. I was concerned it was the machine.

Sometimes things go on edge and that throws a wrench in!
