Ok I am torn between adding a AT PRO or another Tesoro to my arsenal? Anyone have experience with both have any suggestions? The AT PRO really gets my attention due to it being water proof. However I like a machine with threshold the screens don't mean much to me. I swing a Sand Shark on the beach and have been happy with Tesoro. The lifetime warranty makes sense to me. I want a machine that can handle some beach use but a upgrade to my Fisher F2. Looking to pull the trigger soon. The Vaquero has caught my attention. Thanks for any suggestions.
