Want to start doing a little water detecting....Fresh water mostly but salt when I can....No diving just shallow water and sand. I have an Etrac but dont want to use it where a chance of water damage is possible. Is there enough difference in the two detector to pay the extra for the Excal. Is one lighter than the other. I have been told the GT with the WOT coil is a hard combo to beat but I have never used either one so am asking the experts....Thanks for your replies..
