Cobra Duct Rods

18mm Mini Sonde (33kHz)

A 18mm, slim, waterproof powerful 33kHz Sonde transmitter for smaller pipes and ducts for blockage location and pipe traceability.

A rodding sonde for ducts and pipes, the 18mm Mini Sonde is a powerful but slim waterproof 33kHz Sonde transmitter. Designed to connect to Ritelite Cobra Rodding Systems, this rodding sonde provides excellent traceability and blockage location on non-metallic sewers, drains, ducts or pipes especially those with a smaller diameter.

When connected with an appropriate adaptor and used correctly the Mini Sonde transmitter enables any pipe or duct to be accurately tracked, pinpointing the exact route from above ground using a standard CAT and Genny system. 33kHz is the industry standard location frequency in the UK and provides a good signal for underground location up to 7M depth. Requires MIDCOSA to fit.
