Midi Sonde

The Sonde is a dual frequency signal transmitter used to trace drains, sewers and other non-conductive services. It can be attached to a range of equipment including drain rods, boring tools and inspection cameras.

Dual frequency modes

On a busy congested construction site background interference can make Sonde location difficult. The Dual Frequency Sonde enables tracking in either 8 kHz or 33 kHz modes, making it more flexible and convenient to locate.

Measuring only 38mm in diameter and 130mm in length, the Sonde is designed specifically for restrictive environments. Built to an IP67 standard the Sonde can be fully submerged and can cope with the harshest of environments.
