I'm sure you guys have now heard of the AT Pro and how good it is in wet salt water and sand. I used the CZ6a for years and it was awesome in salt water beaches. Never have used the AT Pro but just wondering if some of you guys have used this machine and how does it really compare to the CZ's in wet salt sand use. I read the field report but I've never read a bad one either. I also used the Garrett Groundhog for many years and it was a very good machine but not so great in salt water enviroments. Thanks and good hunting. John
