CAT and Genny

Cable Avoidance Tools

The latest range of  Cable Avoidance Tool (CAT) and Signal Generator (Genny), pioneered by Radiodetection.

C.A.T4® and Genny4® products provide a comprehensive range of Cable Avoidance Tools helping professionals to drive best locating practice, to reduce the number of cable strikes, and to dig more safely. 

The C.A.T4 is the standard model of the range. Using it with the Genny4 transmitter, experienced operators will be able to find more buried utilities, faster.

This model is equipped with an automatic recording system which stores up to 2 years’ worth of usage data in its internal memory. Data can be later retrieved and analysed using a USB lead and a PC.

This model adds GPS position to the usage data recorded. Bluetooth connectivity allows seamless transfer of usage data to the C.A.T Manager Online cloud based system for near real-time monitoring of operators’ performance.

Genny4’s patented simultaneous dual-frequency signal output facilitates location of small diameter cables such as telecoms and street lighting, including spurs. All C.A.T4 locator models have patented technology to detect both signals simultaneously. The power boost function in Genny4 enables the locate signal to travel further and deeper, and couple onto utilities more easily.

C.A.T Manager
C.A.T Manager is a software suite designed to offer online or local analysis of usage behaviours, explore surveyed locations using Google Maps, and produce surveys and usage reports. Data can be exported and shared as KML or CSV files.

The PC version offer the ability to keep fleets up-to-date with the latest firmware and in calibration.
Near-real time monitor of gC.A.T4 and Genny4 fleets is possible using the Android or iOS app and the cloud based C.A.T manager Online.

Drive best practice

C.A.T Manager™ Online and C.A.T Manager for PC provides a remote management system specifically designed for supervisors and safety officers, to enable them identify operators’ locating operations and drive best practice. 

C.A.T Manager Online works with gC.A.T4 models to provide near-real time monitoring capabilities and cloud based data storage and analysis. At the end of each scan the C.A.T Manager Android or iOS apps, automatically transmit the comprehensive 1xsec usage data to the cloud system. 

The C.A.T Manager basic account is free to use and offers access to the last 3 months’ usage, with analysis and survey reporting. 

The Pro and Enterprise options have been designed in collaboration with major UK contractors to provide a range of features designed to enable teams and contracts management, more detailed survey reports and automatic alerts when the C.A.T Manager detects poor practice. 

C.A.T Manager for PC utilises USB 2.0 connectivity to be able to retrieve and store locally eC.A.T4 and gC.A.T4 data logs. Data can be exported and uploaded to C.A.T Manager online for further analysis, storage and to share data across multiple sites. 

Reduce the number of strikes

Small Cable Locate - Dual-frequency locate
Simultaneous dual frequency and simple locating methods assist C.A.T4 and Genny4 users to locate Small Diameter cable such as telecom twisted pairs, CATV feeds, spurs and drop-offs which have historically been hard to find and are a common strike risk 

Dynamic Overload Protection
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. 

Avoidance Mode™
Sweep an area using Power, Radio and Genny signals simultaneously, saving time. C.A.T4 lets operators control the sensitivity of each mode/signal, enabling buried utilities to be pinpointed in a single pass, while Real Sound provides audio feedback derived directly from the utility located, easing identification to maximise speed whilst maintaining safety. 

Genny4 Signal Boost
The Genny4 offers, alongside its standard power mode, a Signal Boost feature which increases the output signal by up to 10 times allowing you to locate over extra distance and depth. 

High Visibility Display with Backlight 
The C.A.T4’s high visibility display helps to minimise the possibility of misreading critical information from the unit. The high contrast and automatic backlight illumination provide optimum visibility in all light conditions.

Improve Safety

Reduce the risk of hitting a shallow cable with the optional StrikeAlertTM warning, enhanced and optimised in the CAT4 range to reduce the instances of false warnings. 

Radiodetection C.A.Ts are designed to respond exceptionally quickly to even the smallest detectable underground signals. 
Radiodetection's research into underground signal detection has shown that the ability of an operator to identify these buried utilities is significantly reduced by careless working practices such as excessive or rapid swinging. 
To further reduce utility strike risks, eC.A.T4 units are equipped with sensors to detect such incorrect usage and warn the operator with an alert that is also stored in the data log.

Service and Calibration


Minimise the risk of having to delay a survey because a C.A.T4’s calibration has expired. eC.A.T4 series products provide a 30 days countdown warning to the expiry of the calibration certificate. The optional CALSafe can be set to prevent the unit from operating outside the calibration period, ensuring compliance with company policies – and the interval required between services can be customised within a 1 year period using the C.A.T Manager software. 
C.A.T Manager for Windows PC allows plant, fleet and site managers to minimise down time by performing software upgrades, reproducing calibration certificates and performing online calibrations using eCert. eCERT provides a fast and thorough test of key circuitry elements within C.A.T4, and validates their performance against the original factory calibration over the internet 
It also gives the ability to turn on or off C.A.T4 features such as Strike alert or Swing Warnings**. 
**Model dependant 

eCert provides a fast and thorough test of key circuitry elements within C.A.T4, and validates their performance against the original factory calibration over the internet. eCert, activated through the C.A.T Manager PC software, provides a fast, thorough and convenient test of the key locating circuitry within C.A.T4, and validates its performance against the original factory calibration. Following an eCert test pass, a Radiodetection Calibration Certificate for that C.A.T4 can be printed or saved. What's more, C.A.T Manager can reproduce the original factory calibration certificate, or any eCert certificates that it has produced, on demand. For a complete maintenance package, Radiodetection also offers exhaustive factory-backed service and recalibration options including full mechanical integrity inspection and function testing.


Radiodetection’s C.AT4 and Genny4 offer a comprehensive range of Cable Avoidance Tools designed to provide operators with locators that are both simple to operate and offer a range of options and features to improve survey speed and accuracy.

  • Simultaneous dual frequency helps locating Small Diameter cables.
  • Dynamic Overvoltage Protection enable the locator to operate in electrically noisy areas.
  • Avoidance mode, speeds the survey by searching for Power, Radio and Genny signals simultaneously.

As a safety critical tool the CAT4 range also offers a number of features designed to support safe working and help to drive utility strike rates down.

  • StrikeAlert warns of the presence of shallow cables.
  • SWING Waning, for example, warns the user of incorrect usage whilst CALSafe automatically disables the unit on the expiry of the calibration period.
  • Built in Data logging and GPS/GNSS receiver enables usage and location analysis and reporting.
  • Bluetooth Low Energy connectivity to Android and iOS devices.
  • Service Due indicator and CalSafe help preventing usage of the instruments behind the calibration due date.

The eCERT online service provides the convenience of being able to extend the validity of the Calibration period for another year in the field.

Network Rail Use

The C.A.T4 and eC.A.T4 models, the Genny4 Signal Generator, and their accessories are approved for use on the UK’s national rail infrastructure, managed by Network Rail. 
C.A.T4, eC.A.T4 and Genny4 are accepted for use on Network Rail infrastructure within the defined scope of acceptance and any specific conditions in the certificate. They must be maintained in accordance with the manufacturer’s recommendations.
