How to Use the Sondes
5.9.1
General Information
The sondes are signal transmitters used to trace pipes, ducts, conduit or
drains. A sonde can be attached to a range of equipment including drain rods,
boring tools and inspection cameras. It is powered by its own battery supply,
so unlike other accessories this does not require a connection to the transmit-
ter.
The signal pattern transmitted from a sonde is different to that which is radi-
ated from a utility and requires tracing in its own unique method. The sonde
transmits a peak signal over its main body, with a ghost signal at its front and
back.
