The Radiodetection CAT4 range of cable avoidance tools incorporates a new range of ground breaking safety features which enhance cable detection searching. The enhanced Avoidance Mode allows the operator to check an intended excavation area for Power, Radio and Genny signals simultaneously, pinpointing buried utilities in a single scan.

Radiodetection’s unique digital signal processing capabilities equips the C.A.T4 with the ability to reject electrical interference. Dynamic Overload Protection gives C.A.T4 series products the ability to continue operating in electrically challenging areas, such as near substations and under power cables, where other locators’ detection circuitry may be overloaded and no longer function.

All C.A.T4 models incorporate Dynamic Overload Protection, a powerful signal processing tool that identifies and automatically rejects electrical interference that may otherwise overload the C.A.T’s electronics.

Dynamic Overload Protection allows the operator to locate pipes and cables in electrically noisy environments such as near power sub stations or near overhead high-voltage cables.

In all locate modes the bargraph and sound levels increase as the C.A.T gets closer to a pipe or cable, and reduce once it passes beyond it or as it gets further away.
