The 33 kHz Sonde is a compact signal transmitter designed for UK electricians, groundworks teams, drainage engineers and utility-locating technicians who need to trace non-metallic pipes, ducts and conduits underground. When paired with a compatible locator, it emits a strong 33 kHz signal that helps you pinpoint the path and depth of drains, sewers and ducting where standard CAT & Genny equipment cannot detect metallic content.
How does the 33 kHz Sonde help on-site?
The sonde is easily attached to drain rods or push cables and pushed through pipework, allowing technicians to trace its movement above ground with a locator. It’s ideal for blocked drainage routes, duct mapping, fault location or pre-excavation safety checks. Its 33 kHz frequency provides excellent performance in high-interference environments and offers reliable detection depth for most domestic and commercial pipe systems.
