Used to locate buried plastic Water Pipes, Gas Pipes and any other non-magnetic utility, Sondes are self-contained transmitters that are used with our cable and pipe locators.

Sondes are typically attached to a Flexrod, pushed along the pipe, and the position of the Sonde detected from above ground. The FlexiTrace product allows the entire path of the pipe to be located, rather than just the end.  Blockages can be located by pushing until the Sonde stops, and then locating that position.

Our comprehensive user guide covers Radiodetection’s range of Sondes and associated accessories, including Flexrods and FlexiTraces, which can be used in tracing the paths of pipes, ducts, sewers and drains, and in the precise location of blockages or collapses.  Check the Sonde frequency to ensure that it can be detected by your Radiodetection cable and pipe locator or cable avoidance tool.
