MD-88 Deep Ground Metal Detector Gold Detector Pressure Stone Diamond Detector With Two Coils

MD88-type metal detectors used high-power launch, automatic tracking system, it is pro 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. The formation of a wide RANG E of minerals, they will also have a metal detector signal, a signal of some minerals will cover up the signal swap metal 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 Give n by the alarm sound, a phenomenon known as "mineralization "Developing the under metal, 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 STROB E signal, eliminated 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 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, detecting deepened when the apparatus is the best penetration but vulnerable to clutter interference. Features: 1. Rechargeable, Battery Life L.E.D lights charging indicator lights 2. Full-control ground Balance 3. Distinguish Ferrous and Non Ferrous me 4. Be capable of remarkable depth and extreme sensitivity in the worst grounds 5. Waterproof 15" search coil. 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. The shell is made of high-strength ABS engineering plastics with high strength, light weight and long service life. 9. Can effectively and accurately distinguish the function of ferrous metal and non-ferrous metal; 10. Ground balance line can eliminate the influence of "mineralization reaction" and effectively improve the depth and accuracy of detection; 11. With under-voltage working alarm device; 12. Metal sound detection through speaker or headphone recognition.
