Now that I've found a gold ring on the beach I'm hopelessly hooked on beach hunting.Is the Excal II a better choice for the beach over the Sov. GT?I would hunt out to about 3 feet deep on calm days.Is there a place I can send my Sov.GT(after I purchase one) to get it put in a waterproof box?I like the idea of being able to use different sized coils and Grey Ghost Water Proof headphones.Thanks in advance.Bill
