The Pro-Find 20 offers essential core pinpointer features in a waterproof housing, designed for simplicity and ease of use with audio and vibrate target indication. Audio tones intensify as the probe approaches the target, making target location easier than ever. Vibration Response lets you feel the target signal, even when Audio Indication is turned off. Locate coins, rings & gold with speed and accuracy. Advanced features include Minelab’s Detector Interference Free (DIF) technology that significantly reduces interference with an operating metal detector, when the pinpointer is switched off, by disengaging the pinpointer coil’s magnetic field.​ Pro-Find series pinpointers also feature a useful lost-alarm that will sound after a period of inactive use. This makes it easy to locate your forgotten pinpointer, even in long grass, so you never leave it behind. The Pro-Find 20 is waterproof to 1.5 m (5 ft) for accurate detection of targets in shallow water. The Pro-Find 20 box includes a tough, semi-rigid holster attaches to any belt to keep your pinpointer at the ready.
