Waterproof Ground Metal Detector with Discrimination Mode

The same electromagnetic induction principles Maxwell formalized in the 1860s now let you distinguish buried iron from silver at 25 cm depth.

Ground-penetrating metal detectors work by transmitting an oscillating magnetic field and analyzing the phase shift of eddy currents induced in conductive objects. Discrimination circuitry filters ferrous junk from non-ferrous targets by comparing the phase angle of the return signal — pure applied physics every time you pull the trigger. Fully waterproof search coil handles beach hunting, stream beds, and wet soil.

• Detection depth up to 25 cm (iron), 20 cm (coin-size non-ferrous)
• 5-segment discrimination display with adjustable sensitivity (10 levels)
• Waterproof 26 cm DD coil — submersible to 1 m
• LCD target ID with pinpoint mode; 2× AA batteries, 20+ hr runtime
