MD88 GROUND SEARCHING METAL DETECTOR  

MD88-type metal detectors used high-power launch, automatic tracking system, it is sufficiently probing depth and accurate identification ability is super-professional deep-detectors, particularly applicable to the detection of deep strata operations. The device has Discrimination and Ground Balance function. Could be charged directly. Has big and small search coils, earphone and charger.

Specification:
1. Rechargeable, Battery Life L.E.D lights, charging indicator lights.
2. Full-control Ground Balance. 
3. Unlike any other metal detector on the market today, MD88 could distinguish Ferrous and Non Ferrous metal
4. Be capable of remarkable depth and extreme sensitivity in the worst grounds.
5. Waterproof 15" search coil. Other accessory 12" coil available.
6. Threshold Control. Accurately adjust the audio to hear the smaller, deeper signals.
7. Frequency Control adjusts for hunting near power lines, microwave or other environmental interference.
8. English Panel, easy operation
9. Two-year Parts and Labor Warranty. Lifetime Service.

Metal buried in the ground, we, through thick layers to exploration, geological structure will inevitably be affected. Formation contains a wide range of minerals, they will also have a metal detector signal, a signal of some minerals will cover up the signal swap metal caused illusion. The old test used metal has such experience, with the key in the probe ground surfaces, the signal also followed changes in the probe near the mound, stones, bricks would be given by the alarm sound, a phenomenon known as "mineralization reaction. " Because of this, the old metal detector test can only detect metal in the shallow soil, buried deep under the ground metal target is powerless. MD88-type apparatus equipped with advanced balance system, metal only strobe signal, eliminating the "mineralization reaction" interference, greatly improving the detection apparatus depth.

MD88-type machines used "level with the" design, random with a probe size of the two, under normal circumstances, such as soil conditions indoors or more complex, connected to a conventional small probe detection. Conventional detection work stability, and distinguish between accurate and anti-jamming capability of soil. In exceptional circumstances, such as in the field of soil uniform lots, the goal of finding buried very deep, can be connected to the probe to enhance detection, detection deepened when the apparatus is the best penetration, but vulnerable to clutter interference.
