I own the 3 Explorers,XS,II + SE and am thinking of the CTX..I just beach/shallow water hunt and have no use for the GPS nor the wireless headphones for that matter.My question is,do many of you use the GPS feature on the 3030 ? I would think anyone artifact hunting in wooded areas would already own + use a portable GPS and I dont see a need for a beach hunter.Plus it adds to lost time switching in and out of programs and increases the price of the machine...Thanx,Ralph
