KD-2125 adopts multi-frequency detection technology with a high-power transmitter and user-friendly digital receiver. It features high automation, strong anti-interference and accurate positioning, suitable for non-professionals to achieve professional detection results for underground pipeline surveys.

1. Compass display for intuitive visualization of pipeline position.
2. Left and right arrow indicators to show the exact pipeline location.
3. Tracking prompt function to detect pipeline current direction and eliminate adjacent line interference at specific frequencies.
4. Real-time measurement of pipeline burial depth and current value.
5. Historical curve display for intuitive observation of signal variation trends.
6. Unique identification with optional clamp (clear results) and stethoscope (for special working conditions).
7. Ground fault location with optional A-frame, no zero adjustment needed and arrow indication for fault direction.
8. Digital high-precision sampling and processing with narrow receiving bandwidth and strong anti-interference ability.
9. Multiple detection frequencies supporting active and passive detection modes.
10. Transmitter with three signal output modes: direct connection, clamp coupling and radiation induction.
