Everyone from the casual beachcomber to longtime divers will appreciate the impressive metal-finding prowess of this amphibious metal detector. Working the beach, wading in the shallows or diving for treasures, the Excalibur II moves seamlessly from land, beach and wet sand conditions to underwater depths of up to 200 ft. Broadband spectrum (BBS) technology, combined with superior ground-rejecting technology, puts this units accuracy and depth capabilities in a class by itself. Highlights include a unique method of ground canceling that eliminates false signals from detecting in saltwater and a saltwater-resistant slimline coil for reduced weight and improved balance (in your choice of 8 or 10). RCB amplifies weak target signals inside the coil, reducing noise and boosting faint, deep objects. Powered by a NiMH rechargeable battery pack for up to 12 hours. 17 frequency technology (1.5kHz-25.5kHz). High-visibility fluorescent bodywork. Available: 8 coil, 10 coil.
