Detect metal Max depth: 1.5 meters. Ferrous/non-ferrous discriminator. Distinguishes iron or steel from silver and gold
MD-2500 GROUND SEARCHING METAL DETECTOR
Introduction: This kind of metal detector is manufactured with advanced technology. It has such good characteristics as accurate orientation, good discrimination ability, easy operation and so on. The metal detector is mainly used to detect and discriminate metal substances which are underground. It is widely used in such fields as precious metal objects detection; ancient relics investigation, safe-examination; industrial product exam and relics seek. It is a detecting instrument easy to operate and take.
Function: (1) Ferrous/non-ferrous discriminator distinguishes iron or steel from silver and gold. (2) VLF, Very low frequency designed for accurate detection. (3) Waterproof search coil in the maximum depth of 200mm. (4) Ground Balancing Control tunes out false signals in areas with profuse minerals. (5) Indicating Way: Visual Level Meter with ferrous/non-ferrous indicator lights; 2Speaker or1/8" Earphone (Earphone not included, equipment has a 1/8" Earphone jack) (6) Three distinctive audio alerts for different types of metal. (7) One touch auto tune button quickly resets the tune back to the condition you set. (8) Battery test lets you know whether the batteries is enough of voltages (9) Length adjustable shaft for most comfortable use. (10) Adjustable arm rest minimizes strain on your forearm.
