Coil Thunder is the latest development from the engineers at NEL that combines both high levels of detection depth and selectivity. Working with a slow swing will maximize its ability in finding not only large and medium targets but small targets which weigh less than 1 gram at 20 cm deep as well. The Thunder coil is suited for finding coins, treasures, and artifacts in the field of military battles in any region world-wide. NEL Thunder is a DoubleD search coil with dimensions of 14.5" long x 10.5" wide and weighs 20.1 Ounces, 570 Grams. 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.
