Just wanted to ask about diamond selector ll.

[G Freeman]

Bought a diamond selector ll the other day and wanted to know if anyone on here has ever tried one and if so maybe I can find out how accurate they might be as I have some large quarts crystals at least I think its quartz and I am getting a beep up into the red zone in a place or two. Thanks a lot.

None of these style of instruments are perfect, they may give an indication but nothing more.
