Radiodetection C.A.T4 Cable Avoidance Tool

C.A.T4_Cable Avoidance Tool

Many professionals around the world, work underground. Radiodetection’s C.A.T4 Cable Avoidance Tool allows you to locate utilities buried underground (which generate their own signal). The C.A.T4 has been built upon an established functionality of Radiodetection’s older cable avoidance tools. The Cable Avoidance Tool delivers a comprehensive digital locator that’s highly sensitive, easy to use and crammed with functionality.

Radiodetection’s C.A.T4’s a comfortable piece of kit to use no matter the conditions. The Cable Avoidance Tool includes an ergonomic handle to contentedly grip during use. The Tool’s strong yet lightweight ABS case provides casing rated to IP54 for use in all weather conditions.

Built-In Loudspeakers give indications that underground utilities have been detected. The loudspeaker can detach from the unit allowing a clearer reading during noisy environments. Noises generate alerts to the specific types of buried utilities. Generated noises help you determine exactly where utilities are, as well as the type of underground utility that’s currently undergoing inspection.

‘Dynamic Overload Protection’ Filters out unwanted electrical noise commonly found in and around electrical sub-stations and surface mounted HV cables; these can have an adverse affect on the detection of buried utility locations. Signal strength displays upon a high-contrast backlip LCD screen that features a bargraph ‘tidemark’ allowing for quick and easy pin-pointing of hidden utilities.


Operating modes included as standard with the C.A.T4:


CAT4 Optional Extras Sheet.

Avoidance Mode

This allows you to simultaneously search for and pinpoint Genny, power and radio signals.

Genny Mode

Detects signals generated from a Genny4 signal generator, with on-demand estimation of buried utility depth (depth function depends on model selected).

Power Mode

On use detects Electromagnetic fields generated by the surrounding buried power cables.


The StrikeAlert feature presents a visible indication of utilities that are located close to the surface of the ground that would present a potential ‘Strike’ risk if left undiscovered.




*** Importantly please note that the C.A.T4 cable avoidance tool should predominantly accompany Radiodetection’s Genny4 Signal Generator. ***
*** This allows for hidden utilities that do not generate enough EMF or radio signal to detect the C.A.T4 alone. ***
