Minelab's unique Broad Band Spectrum (BBS) technology, combined with superior ground rejecting technology, makes the Excalibur II the ideal underwater machine. The unique design of the Minelab Excalibur II allows you to use it as effectively in or out of the water - this amphibious machine can move seamlessly from land, beach and wet sand conditions to underwater depths of up to 200ft (66m). Thanks to a unique method of ground cancelling never again will you get false signals from detecting in salt water. Enjoy the simple yet effective discrimination and be surprised at the sensitivity and depth you uncover targets from.
