I see a lot of new machines coming out of the uk, with strong point's , and weak point's, this machine appears to do good in the black sand, however burring a coin at 9 inches , and getting a weak signal wasn't impressive , as the tester said, my F75 se with the 5 inch coil hits harder at a coin at nine. The CTX3030 with the stock coil is deeper, i think the Uk manufacturer's are trying to get a piece of the beach-water- action, but i think they have a long way to go, i see you getting , and selling several machine's made from the UK, some look like they do well in dirt, but for now the Excalibur's, CZ21s , Df, CTX3030s , and soon the Equinox series are the top gun's, good luck in testing those machines out at the beach, wish you luck in your experimental journey , happy hunting.
