Equipped with a waterproof search coil, this metal detector locates coins, relics, and jewelry across beaches, rivers, and parks. Two detection modes separate iron from valuable targets on the clear Lcd display, while the stem adjusts from 3.3 to 4.2 feet to suit adults and kids alike. A 7.5 kHz signal reaches items up to 6.3 inches underground, and the included headphone jack keeps every beep private during treasure hunts.
