I don't have an Excalibur II but I have the last edition of the Excalibur and yes it goes plenty deep. The best thing about my Excalibur is the fact that it ignores iron which there is plenty of on every beach. I hunt in the surf here in Florida and find plenty of coins and rings. My problem is getting off to hunt when the beach is user friendly. It seems every time the beach calms down enough for me to hunt I am at work and when I am off the surf is just right for surfers. I have the 10 inch coil version and absolutely love using that detector. Rule number one, if it sounds off dig.
