RadioDetection CAT4 Cable Avoidance Tool (EN09 / EN29)

The RadioDetection CAT4 is the standard tool for locating underground services, to help minimise the risk of costly and dangerous underground utility and cable strikes.

Both the CAT4 and eCAT4 avoidance tools are approved for use on the UK's national rail infrastructure, managed by Netwrok Rail.

The CAT4 is battery powered, with an ergonomic design that allows one handed operation. The mode select switch and sensitivity control can be adjusted whilst using the CAT for quicker and more precise measurements. The unit also contains a light sensor which automatically activates the backlight in low light environments.

CAT and Genny

The Genny4 (available separately) provides a simultaneous dual frequency signal output, to help locate a specific target line or utility.

  • 33 kHz: Ideal for locating general purpose utilizes
  • Small Diameter Locate: Designed for locating telecoms and street lighting and CATV cables
  • Boost mode: increase signal strength by 10 times for difficult locates

RadioDetection CAT4 Vs CAT4+

Both are designed to locate utilities with a 'single scan' approach, however the CAT4+ enables refined cable location capabilities thanks to its depth estimation feature. When used in conjunction with the Genny4 (available separately) the user can press the depth button on the CAT4+ to display the estimated depth on the tools high visibility display.
