First, I have never used the CZ-3D at the saltwater beaches in the wet sand because of possible falling down like I seem to do when I don't have a waterproof detector. Any detector operates fine in the dry sand. But since the CZ-3D and the CZ-20/21 both operate at two different frequencies they should both be great. The CZ-20 & 21 are both very good at the saltwater beaches and in the water too.
yea "Sandman" thanks for the info....I have a tired 1995 CZ-20 and as a matter of fact I just received my new CZ-21 today from UPS....I was thinking of getting the wife a CZ-3D....
