Feature:
1. Metal detectors are used to detect and identify the main saphenous buried in the ground floor of metal objects, in addition to military uses
2. Ground Ballance can exclude mineralization reaction to make sure where is the metal and gold.
3. Coordination function and Discrimination function can distinguish kinds of metals.
4. Earphone can help you operate in noisy and dark situation.
5. English Panel, easy operation
6. Two-year Parts and Labor Warranty. Lifetime Service.
It also can be used: Customs inspection and safety check; the public security departments cracked Interpol search; detection of raw materials, fuel, metallic foreign body in food; check mail, baggage and parcel of metal objects; exploration underground pipes, lines; exploration iron, prospecting, archeology; found buried in the ground floor of metallic gold and silver treasures and relics; scrap metal recycling;
The old test in the use of metal detectors, the most unpleasant question is the impact of the ground. As the distance between the probe and ground equipment changes also followed changes in the signal, if the probe rugged key in the ground, the change is even greater, the operator heard everywhere as if acoustic signals about the buried metal where real. This phenomenon is called "mineralization reaction." A "mineralized response" because the soil is due to a variety of minerals to send a signal equipment in the local soil structure complex "mineralization response" very strong signal caused by its signal will be even higher than the metal, then operation staff sent a signal to hard to judge where in the end is buried metal or "mineralization reaction." MD-90 machines are equipped with balanced lines, to eliminate all "mineralization reaction" effect only when the metal probe encountered a signal, thereby greatly improving the probing depth and accuracy.
