The Snake Coil is 6.5" long x 3.5" wide and designed to search areas heavily littered with iron and other trash debris. The elliptical shape of the coil helps to separate nonferrous metal from iron. The coil is light and weighs in at 10.5 Ounces, 300 Grams with coil cover. The coil has good sensitivity to large, medium and especially small targets. Very easy to use and is excellent at pinpointing targets. The coil is waterproof and fully submersible, the body is filled with epoxy resin. Additionally a black protective coating, the same as used on marine boats, makes it possible to use the coil without coil cover. The coil copes excellently with high and medium soil salinity. One of the best coils for metal detecting for jewelry on beaches. Recommended for professionals and amateurs! Includes coil cover, hardware and Velcro cable strap. 2 Year Warranty. For use with the Minelab Sovereign Metal Detector.
