The SuperCAT4+ range of locators and transmitters uses a selection of passive, sonde and active frequencies designed to target specific buried assets. Using Radiodetection’s familiar C.A.T controls and display, minimal retraining is required to access these advanced capabilities.

For oil and gas pipes using a Cathodic Protection System, the CPS model can locate the rectified signal without needing an additional transmitter.

The S model locates a range of sonde frequencies that can be matched to the challenges of finding water and drain pipes. A lower frequency sonde is useful to trace deep cast-iron pipes. Higher frequency sondes can be easier to distinguish in an electronically noisy urban environment.

SuperCAT4+ can be used to locate a comprehensive set of active frequencies to support the detection and tracing of different cable types in varied environmental conditions. Higher frequencies such as the 131kHz or 65kHz can be used to find well-insulated utilities such as twisted-pair telecom cables or insulated pipe joints. For long range locating of lower resistance cables, such as power lines, lower frequency options are available.

Safety Built-In

All SuperCAT4+ models come with a range of features designed to aid safe working practices.

Dynamic Overload Protection

High levels of electrical interference, as found around substations and near high-voltage transmission cables can overload sensitive electronics. Dynamic Overload Protection filters this interference out, enabling SuperCAT4+ to continue locating where other units struggle.

Dig more safely with StrikeAlert™

StrikeAlert warns the user to the possible presence of shallow cables and utility lines in both Power and Active Line modes.

Although work practices and guidelines insist power cables are buried below a certain depth, a common cause of cable strikes is unexpectedly shallow cables.


Indicates depth when the locator is oriented correctly above the target cable, pipe or sonde for the most accurate reading.

Real Sound

The audio signals emitted by the SuperCAT4+ are derived from the signals detected. Radio, Power and Active signals can be easily distinguished from each other, and from background noise, helping identification of target utilities, and aiding differentiation of closely co-located utilities.
