These are called Hot Rocks as they have a mineral content which sets off the detector. Not much you can do about them as to much disc. to eliminate them loses a lot of gold rings. Best way I know of to not hear them is to use a Excal, but that's kind of expensive just to stop hearing Hot Rocks. Course you have to figure what your time is worth. Most sites don't have a lot of these. When I retrieve one, I drop it in my trash pouch so I don't have to dig it again next time.

I know a couple waterparks where they dumped cinders under the water slides because the small cinders were heavy and stayed put. Waving a detector there is like waving it over your car hood.

One of m my favorite beaches has a lot of small rocks that are slightly hot and cause the detector to chatter, occasionaly sporadically chirping. Now and then I find one that makes a real signal, but not often. I think it's just one of those things you learn to cope with, like Sandman says.
The few big ones Ive found have a sort of swelling tone, not like the sharp report of good targets. It helps to discern them, and in the water you need all the discernment you can get - there are precious little other clues as to a targets real identity.
