Sondes & Adapters

Sondes and adapters together form the complete insertion signal source assembly for locating non-metallic buried pipes, drains, and conduits from the surface. The sonde provides the electromagnetic signal from inside the pipe. The adapter connects the sonde to the push rod, drain rod, or inspection camera system used to drive or carry it through the buried structure. Without the correct adapter, the sonde cannot attach securely to the insertion tool, creating signal loss risk and retrieval difficulty during the survey operation.

Sonde transmitters operate at standard locating frequencies including 512 Hz, 8 kHz, and 33 kHz. Outer diameters cover 16mm mini sondes for small-bore pipe access up to 65mm for large-bore drain and sewer inspection. Waterproof sealed housing protects internal electronics during operation in water-filled pipes and submerged drain sections. Battery duration runs between 8 and 40 hours per set depending on sonde size and transmitter power output. Additionally, detection depth from the surface reaches between 3 and 8 meters on compatible locator receivers under standard soil conditions, covering the full burial depth range of typical domestic drain and service pipe installations across Pakistan’s urban areas.

Adapter types cover several connection configurations. Threaded adapters connect sondes to standard drain rod sections in 25mm and 32mm thread sizes used across UK-standard and metric drain rod systems common in Pakistani municipal infrastructure. Friction-fit push rod adapters grip the sonde body securely for insertion through flexible push rods used in drain inspection and camera survey operations. Additionally, inspection camera nose adapters mount the sonde directly behind the camera head on CCTV drain inspection systems, transmitting the sonde signal simultaneously with camera operation for combined visual inspection and route mapping in a single survey pass.

Quick-release adapter designs allow fast sonde swap between differently sized sonde bodies on the same push rod set without tools during field survey operations. Moreover, stainless steel and glass-filled nylon adapter construction withstands the mechanical stress of pushing through bends, root intrusions, and debris blockages in drain survey conditions across Pakistan’s aging municipal drainage infrastructure.

Tactical Supply Pakistan supplies sondes and adapters to drainage survey contractors, municipal sewerage inspection teams, civil engineering survey firms, and utility maintenance operators requiring complete insertion signal source assemblies for non-metallic pipe location and drain survey applications throughout Pakistan.
