Was hunting for a lost diamond stud earning and found out my pinpointed can't find a gold stud or the gold back clip. what pinitointers will, also any of them waterproof?
I have found no problem finding the smallest targets, good or bad, with the Garrett Pin Pointers (Black and carrot). I am sure many other brands will also find very small targets.
A friend and myself have tested the Garret Carrot and Garret’s Black pinpointer "name escapes me" on some small gold that had been panned in a vial and neither would detect it.
My CTX and his ETrac wouldn’t hit on it either, so when I go prospecting I’ll be getting something different for sure.

The one I found to work the best on tiny targets was the Uniprobe, but, I don't think it's made anymore. My old TinyTec would find tiny stuff too, but, that hasn't been made for decades. My E-trac and Equinox 800 will find targets that my White's TRX, and Vibraprobe won't detect. I have to go old school and run handfuls of dirt/sand over the coil to find it.
More backup that Garret will find it with no problem. I use the trick of boosting sensitivity buy putting a paperclip on rubber band getting it close enough to tip to sound off then backing it off till quiet, that will about double the sensitivity to small objects.
