  • ‘SWING warning’ – ground-breaking feature warns operators of incorrect usage (excessive and rapid swinging of the instrument) to promote best working practices.


  • Data acquisition – log over a year’s worth of locating data that can be downloaded by USB and reported on using the optional CAT Manager Software package (available to select from above). Not only suitable for project management, but data can be analysed and used to highlight poor working practice.


  • CALSafe and service indication – once activated, the gC.A.T4 tool will automatically ‘lock-out’ upon setting a calibration expiry date. A service reminder indicator can also set to count down 31 days to inform the user of an imminent calibration service.


  • ‘StrikeAlert’ – a feature that warns the operative of utilities that are situated at a shallow level underground that could threaten a possible ‘strike’ risk.




In some cases utilities may be too deep or far away for the gC.A.T4 to locate by its own means, Radiodetections Genny4 will help these types of struggles. The Genny4 signal Generator inducest a dual frequency in the ground for the gC.A.T4 to locate the otherwise hidden utilities etc.

(Genny4 sold separately)


The Radiodetection gC.A.T4 of the 4 user modes as below:

  • Avoidance mode – detect genny, power and radio signals at the same time
  • Power mode – detect EMF signals that surround live underground power cables
  • Radio mode – detecs long wave radio signals travelling along buried pipes/cables
  • Genny mode – receives signals created by the Radiodetection Genny4 Signal Generator


All of the C.A.T4 Cable Avoidance Tools feature ‘Dynamic Overload Protection’. This means the instrument filters out nuisance electrical ‘noise’, which can generate in environments where electrical machinery’s operated that can have an adverse affect on accurately locating underground services.
