Feature:1. Built in Induction Coil: The receiver has a built in induction coil to receive the magnetic signal from the pipeline, and the coil generates induction current to calculate the direction and position of the transmitter2. Widely Used: It can be used for water supply pipeline, cable pipeline, pipeline vacuum system, industrial pipeline, underground pipeline construction, underground cave exploration, underwater research and other exploration work3. 512HZ Transmitter: The receiver uses a 512Hz transmitter, which can easily determine the position of the probe. Save time and money, and take advantage of this great function4. LED Display: The pipeline detection positioned is equipped with LED display. You can view the monitoring data more clearly, conveniently and practically5.
