The hidden line buried line fault detector is a special instrument for power, broadcasting, post and telecommunications departments, as well as industrial and mining, rural areas to find underground cables, including direct buried armored cable lines and buried line faults. It can detect the direction of the buried line, the more accurate underground position, the basic buried depth, and various ground leakage faults, broken core faults, including lines under paddy fields, cement roads, bricks and stones, asphalt roads, and lines in the walls of buildings. Waterproof wires and cables used on the ground can be detected by using this instrument through appropriate methods.
