Basic classification of metal detectors

Underground type


Underground metal detectors are used advanced technology, it has a wide range of detection, accurate positioning, strong resolution, easy to operate and so on. Metal detectors are mainly used to detect and identify buried underground metal objects. In addition to military applications, it is also widely used in: safety inspection, archaeology, prospecting, search for scrap metal. Also known as "Exploration Iron" is a good helper for waste recovery.
Underground metal detectors using sound alarm and instrument display, the depth of the probe is closely related to the area, shape and weight of the metal being explored, generally speaking, the larger the area, the larger the quantity, the greater the corresponding depth of detection; Conversely, the smaller the area, the less the quantity, the smaller the corresponding depth.


Main functions


The effect of "mineralization reaction" can be eliminated by the ground balance line, which greatly improves the depth and accuracy of effective detection.
Has the distinction between ferrous metal and non-ferrous metal function;
Adopt intelligent operating system;
Using high strength ABC material package, light weight, long life;
Metal sounds can be identified by headphones.


Metal buried in the ground, through thick soil to detect, is bound to be affected by the geological structure. The strata contain a wide variety of minerals, and they also cause the metal to detect signals, and some mineral signals will mask off the metal signal and cause the illusion. Using the old metal detectors have this experience, with the probe near the mound, stones, bricks will be issued alarm sound, this phenomenon is called "mineralization reaction." For this reason, old-fashioned metal detectors can only detect metals in shallow soil and are powerless to target metal buried underground. The Canine God underground Metal detector is equipped with advanced Earth balance system, which can eliminate the interference of "mineralization reaction" and greatly improve the detection depth and effect of the instrument.


Hand-held
A handheld metal detector is designed to detect metal objects carried by people or objects. It can detect the carrying or wrapping of a person, baggage, letters, fabrics, etc. with weapons, explosives or small pieces of metal objects. The special appearance of its sensitive surface makes it easy to operate. Better than the annular sensor-type hand probe. Ultra high sensitivity, special application. such as prisons, chip factories, archaeological research hospitals.
