S6 MicroSonde Kit 33kHz

The S6 MicroSonde Kit is a small transmitter sonde. It traces non-metallic pipes and ducts that a standard cable locator can’t detect. The sonde pushes into a pipe, drain, or duct using a rod. It can also travel with the flow of water. Once inside, it transmits a signal at 33kHz. A compatible receiver picks up this signal from ground level. The sonde’s diameter is small. It fits sewer lines, drainage pipes, and conduit runs as narrow as 40mm, common in residential and light commercial plumbing.

Detection depth from the surface typically reaches 3 to 5 metres. This depends on soil type and pipe material. The 33kHz frequency cuts through most soil conditions without much signal loss. Higher frequencies often struggle in wet or clay-heavy ground. Battery life runs several hours per set. This covers a full day tracing multiple pipe runs on one job. The housing is sealed and water-resistant. This matters since the sonde often travels through pipes carrying wastewater or drainage flow.

Operators feed the sonde in by hand or push-rod. Sometimes they let it travel with water flow inside a drain line. The operator then walks the surface above with a receiver tuned to 33kHz. This marks the exact path and depth at multiple points. It avoids the guesswork of digging test holes before repair or connection work.

Plumbing contractors use this kit to trace blocked or damaged drain lines before excavation. Utility companies use it to map non-metallic conduit runs missing from older site records. Construction survey teams also rely on sonde kits to confirm buried duct routes before nearby digging work.

Tactical Supply Pakistan supplies the S6 MicroSonde Kit 33kHz to plumbing contractors, utility companies, and construction survey teams across Pakistan. The kit pairs with standard 33kHz-compatible locators already in use on many job sites.
