'Function and use'
WN-488 underground pipeline detection locator for the detection of underground metal pipe, cable routing direction, location and buried depth in the pipeline-intensive areas of the complex can accurately track the target pipeline and positioning. In engineering excavation, railway, gas, electric power, factories and mines, communications and municipal construction and geological exploration and other departments.

'Features'
● All-digital signal processing technology, the new integrated circuit design. High-performance anti-jamming capability;
● Intuitive and rapid route to the direction of the pipeline;
● a key to measure the depth of the underground pipeline;
● Target pipelines can be identified in the case of multiple pipelines;
● Receiver gain automatic adjustment, so that the receiver is normally in an optimized state;
● battery power real-time detection, when the power is low to protect the value of the alarm will automatically shut down;
