ALPHA DT3

Multi-Function Pipeline Detector

The ALPHA DT3 is the latest multifunctional pipeline detector developed by AlphaGEO for detecting pipes, cables, optical fibers, etc. Its transmitter has a high power output up to 15 watts, and its locator has multiple modes for locating the target. It can accurately determine the position, path direction, and burial depth of underground pipelines. With optional accessories, it can also identify target cables even in complex cable networks and precisely locate cable grounding faults. As a comprehensive solution in the field of detection, it truly achieves multi-purpose functionality, significantly reducing usage costs.
