The Dart Systems Rodding Sonde is a versatile and powerful, self-contained waterproof transmitter. The Sonde can be attached to Flex Rods, Cobra Rods, Drain Rods or any movable device that can be propelled inside non-metallic pipes. Used correctly you can pinpoint the exact route of the pipe and where a blockage is underground from above ground!
The Sonde emits a strong radio signal which can be tracked above ground using an industry standard Cable Avoiding Tool (CAT) or Cable Locator which operates at the same frequency. This 33Khz frequency is the UK standard Sonde frequency for most applications.
Dart Rodding Sondes are available in 33Khz or 8Khz frequency.
The Sondes are tested to withstand drops from 1 Mtr onto concrete or similar surfaces and are also pressure tested and are rated waterproof to a depth of at least 30 Meters. The M10 bolt can be used to connect the Sonde to a variety of pushrods, Cobras or Duct / Drain Rods. The bolt is fitted with a Nyloc insert designed to ensure that the Sonde will not unscrew during normal use.
Industry standard location frequency in the UK which provides a good all-round signal for underground location.
A high frequency that works well for locating to greater depths.
Transmitting Sondes enable the user to trace non-metallic sewers, drains, ducts or pipes and to locate blockages or collapses.
If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.
