I currently own and hunt the SoCal wet sand beaches with the Soverign GT. I'm thinking about picking up an Excal 1000 so that I can venture out into the surf without having to worry about water incurrsion issues. However, I've read quite a few posts by folks who've had their Excals fail (for a variety of reasons) and had to send them back to the manufacturer for repairs. For those of you who've had experience with both machines, does the GT, in fact, have a lower frequency of repair than the Excal? If so, why?
