Hot Rocks Question

[TwistedTig3r]

I woke up today it was snowing by the afternoon it was in the 50's and beautiful. Crazy weather. So, I had some time time on my hands but no car. I decided to walk to an old ball field I hunted plenty of times and I mean plenty of times. High tones are far and few between, mostly low mixed signals are all that's left. I wanted to play around some and switched to digital screen. Thought I might find a gold ring or two. No luck with gold but pulled about 10 nickels, I think I got those signals down. OK, so on to my questions. I hit a couple of targets that rang up 00-31, HM new to me so I'm diggin' . I cut the plug dig down and nothing. I couldn't get a peep from the pin pointer. I wave the Explorer over the hole and nothing, just like running over clean ground. This happens again same scenario, same result. I am reading that 00-31 is likely hot rocks. I have no experience with hot rocks. Do they disappear? Are they detectable with pin pointer? Would appreciate some insight on them please.

Yes, it seems thats exactly what they hit although I hunt in SF.
Try turning down your Sensitivity a lil and see if this helps some.
They will peg the cursor high right (almost all but bottom left corner of it) in the SmartFind screen.
I have seen they can be a bit funky to pinpoint and have almost too good of a silver sound at such depth. I don't run into them to often but, have on occassion.
Although, I generally will dig anyways because you don't know for sure unless you dig and even more likely to miss a keeper trying to guess.
How deep did you dig and still get no signal?

Not sure if I was any help.
