Ground balance question

[Neil]

I am picking up darker layers of soil....on a white sand freshwater beach. Is my GB off or is that what it should be doing?
I manually ground balanced my shadow X5 and have been switching between three modes.....manual GB, fixed GB and all metal. I pick up the dark soil patches in manual GB and all metal but when I switch over to fixed GB I dont hear it.
Opinions?

hard to say without hearing/being there but if its patchy its hard to combat other than constant GB ing .

go with what ever is getting best depth & sens run some tests in the black areas with coin etc..

Sounds like what you call "soil" may be black sand which is a form of iron and hard to tune out with many detectors.

I think that's it. You can run more positive GB in attempt to tune it out, but you'll likely lose depth doing that. A small DD coil may also help.
Best to avoid the black sand.

soil or sand we are talking the same thing. I run in to it more at the ocean but there I use a minelab and they don't make a sound on it. Its easy to tell its a soil patch by sizing, so I don't dig it often, I was more looking for if this sounds like an optimal setting (hearing the black sand) for finding stuff. I will try ground balancing over it next time out and see how that relates to finds.
