RadioDetection SuperCAT 4 Avoidance Range


Cable Avoidance Tools

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.

Locate pipelines protected by a Cathodic Protection System

Optimized for metal pipes including those that use rectified currents as part of their Cathodic Protection System. The CPS signal can be located and traced without the need to apply an additional transmitter signal to the pipeline

SuperCAT CPS Feature Summary

* Choose between M (Metric) or I (Imperial) locator models

** Power frequency and corresponding active low frequency  set by model , (50Hz – 640Hz and 60Hz – 512 Hz)



SuperCAT4+ CPS models are optimized to detect CPS signals to allow tracing of protected pipelines without disconnecting rectifiers.

SuperCAT4+S and T1-512/640

For the challenge of detecting and tracing buried pipes, the SuperCAT4+ S locates the widest range of sonde frequencies.

Additionally, an active 33kHz frequency can be applied to a Flexitrace using a T1-512/640 for continuous signal tracing.

SuperCAT S summary of features

*Choose between M (Metric) or I (Imperial locator Models

** Power frequency and corresponding active low frequency set by model, (50Hz – 640Hz and 60Hz – 512 Hz)


Sondes enable non-metallic pipes to be accurately traced, depth determined and the position of blockages accurately identified. Sonde


Connect the T1 to a Flexitrace to radiate a continuous tracing signal from non-metallic pipes and conduits.




Detect a broad range of utilities

SuperCAT4+ and T1 Range

Designed to meet the demanding environments of the construction industry, this multi-utility locator can be used with a  wide range of sondes and accessories.

SuperCAT4+ is compatible with all T1 Transmitters. Higher frequency transmitters are recommended for high-impedance cables. Lower frequency signals travel further on lower-impedance services.

Signal Clamping

Safely apply a T1 signal to a pipe or live cable up to 125mm/5” diameter without interrupting the supply.


Direct Connection

The most effective method for connecting to a valve, meter, junction box or other access point, as long as access is possible.

Direct Connection


Conveniently apply a transmitter signal to a pipe or cable when, direct connection or signal clamping is not possible.

  • 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.

  • 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.


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