Handhold metal detectors are highly sensitive to metals, it uses a single battery of 9Volts.with sound alarm or vibrating.they are used in a variety of places, including airport, dock, embassy, army , prison, government building, customs, station, staduium, clunbs, electronics factories, metal factories, cable factories, airport screening, sports, entertainment field, and so on, which is convenient to call out, and makes the adjusting more efficient and effective;

Metal detector walkthrough has built-in smart chip that stores the statistics of sensitivity recommended by a variety of places, including airport, dock, embassy, army , prison, government building, customs, station, staduium, clunbs, electronics factories, metal factories, cable factories, airport screening, sports, entertainment field, and so on, which is convenient to call out, and makes the adjusting more efficient and effective;

There are two pairs of infrared scanning sensors which can rapidly capture the signals of sensor and automatically count up the number of passersby(60-70persons/min). It can eliminate the detect errors due to the sensor delay, reset quickly and count up the numbers of passersby accurately;Multiple devices can work side to side adjacently , without any interference;

Explosive detectors are used for detecting expolsives via remote control.

Mine or underground metal detectors can detect the metals or mine underground either 5 meters deep or more.
