I am sanded in so there is not much on the low tide sand. Everything I find is very deep. Today I found a ring and necklace. Both junk although the clasp on the necklace could be sterling I just haven't tested it yet. The ring is unmarked and I am pretty sure its just steel/tungsten. BUT...I was happy to find each of these. This is the first ring I've found with my CTX (wait or did I find another? I've lost count) and this is the first chain I have found this year. I was very surprised how easily the ctx with 17'' coil was able to detect it.
One thing I also discovered on my CTX is that I much prefer the long pitch vs the pitch hold I was using.
