Pipeline detection range | Direct connection method: Generally, the cable length can reach 0~20 kilometers, which is mainly determined by the ground resistance,
cable resistance and cable burial depth.
Coupling method: Generally, the cable length can reach 0~10 kilometers, which is mainly determined by the ground resistance,
cable resistance and cable burial depth.
Cables buried less than 2m deep |
| Depth and Current | Real-time display of cable depth and current value |
| Pipeline measurement depth | 0-20m |
Depth Accuracy | Plane position precision positioning accuracy: Center axis position
of target cable or pipeline:±5% ( burial depth 0-3m) -10% ( burial depth 3m- 20m) |
True or False Tips | Eliminate interference from adjacent cables. When measuring
adjacent cables, the measurement of adjacent cables can be distinguished based on the different signal strengths and
measured current phases fed back by the adjacent cables. During the
cable tracking process, observe the phase table.

| Sound Instructions | FM tone that varies with signal strength |
| Anti-interference display | Green: No interference
Green: Good (results are reliable )
Red: Severe interference (results are unreliable ) |
Anti-interference ability | The extremely narrow receiving frequency band and unique digital
processing method can fully suppress the power frequency and
harmonic interference of nearby running cables and pipelines. |
Interference distance | When using the coupling method and the induction method, the
transmitter will generate interference within a short distance. The
interference distance is related to the transmission power and
frequency. The greater the power and the higher the frequency, the
stronger the interference.
The minimum distance at which a receiver is not disturbed by a
transmitter often requires experimental determination:
Pipeline detection: Coupling method can confirm no interference beyond 5m , induction method can confirm no interference beyond 20m Cable identification: Coupling method can confirm no interference beyond 2~5m |
