Important Note on Ordering: Optional StrikeAlert Mode

The CAT4 Cable Avoidance Tool can either be ordered as a standard model, or an upgraded model with Radiodetection's StrikeAlert mode included.

StrikeAlert is designed to warn you of the presence of shallow buried utilities, reducing the risk of accidentally hitting an underground object.

You can select which version of the CAT4 you would like by choosing an option from the dropdown box.

About the Radiodetection CAT4 Cable Avoidance Tool

Widely used as the tool of choice by professionals around the world involved with working underground, Radiodetection's CAT4 Cable Avoidance Tool will help you to easily locate underground buried utilities which generate their own signal.

The CAT4 builds upon the established functionality of Radiodetection's older cable avoidance tools, delivering a comprehensive digital professional locator that's highly sensitive, easy to use and packed with functionality.

Multiple operating modes are included as standard with the CAT4 - an Avoidance mode allows you to simultaneously search for and pinpoint Genny, power and radio signals; a Genny mode detects the signals transmitted by the Genny4 (see below for more information on the Genny4); Power mode detects the electromagnetic fields generated by loaded power cables and - if selected above - the StrikeAlert facility will warn you of shallow buried utilities.

Radiodetection's CAT4 cable avoidance tool is made for comfortable use in any conditions - an ergonomic handle allows you to grip the tool during use, while a strong, lightweight ABS case around the instrument is rated to IP54 for use in all weather conditions. A built-in loudspeaker gives indication of detected underground utilities and can be detached from the unit and held closer to the ear when working in noisier environments.

The noises generated by the CAT4 are designed to alert you to the specific type of buried utility - Power and Genny signals can be easily distinguished from each other and from background noise, helping you to determine exactly where utilities are, as well as the type of underground utility detected.

All Radiodetection CAT4 units include Dynamic Overload Protection; when used near high levels of electrical interference (such as those found around substations and near high voltage transmission cables), the CAT4 will automatically filter out this interference, allowing you to keep working without worrying about wrong results or overloading your unit.

Radiodetection CAT4 Cable Avoidance Tool Key Features

  • Used to detect the type and location of underground buried utilities which generate a signal
  • Optional StrikeAlert mode quickly alerts you to the presence of shallow buried utilities
  • Lightweight, ABS high impact casing rated to IP54 for use in all weather conditions
  • Detachable loudspeaker - remove from the CAT4 in noisy environments and hold closer to your ear to pick up the signal
  • High contrast display with automatic backlight - bargraph 'tidemark' allows you to determine the location of the signal by detected strength
  • Avoidance Mode - speeds up the process of pre-dig scanning by searching for power, radio and Genny signals simultaneously with different audio signals depending on type of buried utility
  • Genny Mode - the CAT4 is designed to seamlessly work with the Genny4 signal generator to pick up on generated signals and to allow you to detect utilities which may not generate a signal
  • Power Mode - detects electromagnetic fields generated by loaded power cables
  • Sensitivity control knob
  • Dynamic Overload Protection - filters out interference caused by HV cables to ensure accurate operation
  • eCert Remote Calibration Validation - use optional C.A.T Manager PC software to test the locating circuitry of the CAT4 and validate the results againt the original factory calibration using intenet connection to Radiodetection. When passed, you can then print a new calibration certificate for your CAT4 (this process may involve extra costs - please call for further information)

Application Example

Boost Your Capabilities with a Genny4 Signal Generator

Important note: the Genny4 signal generator is NOT included with the CAT4 as standard. This item can be purchased separately by clicking this link >>

By using the Genny4 signal generator, users of the CAT4 can detect more, and smaller, utilities by injecting a dual-frequency signal.

With the Genny4, you can detect utilities which may not generate their own signal (such as pipes) or use it to find small diameter cables such as telecoms and street lighting, including spurs. The Genny4 works hand-in-hand with the CAT4; you can inject the signal using the Genny4, then use your CAT4 to detect the signals generated by both the Genny4 and other buried utilities.

The Genny4 also includes a signal boost mode - this increases the output of the signal by up to a factor of 10, enabling you to locate deeper utiltites and trace over wider distances.

Genny4 units are designed to be entirely flexible - you can combine these generators with various optional accessories to connect to plastic ducts, ceramic pipes etc. Accessories including signal clamps, mouse, live plug/cable connectors and high strength magnets are all available for the Genny 4.

Radiodetection CAT Series Comparison Chart

The CAT4 is the standard model in this series - why not consider upgrading instead to one of Radiodetection's higher-spec units?

The following table shows the difference between each model in the series.

FunctionFunction DescriptionCAT4 >>CAT4+ >>eCAT4 >>eCAT4+ >>
Avoidance Mode Simultaneously searches for and pinpoints Genny, Power and Radio* signals (radio detection depends on model selected)
Genny Signal Locate Detects signals generated from a Genny4 signal generator, with on-demand estimation of buried utility depth (depth function depends on model selected)
Power Signal Locate Detects the electromagnetic fields generated by loaded power cables
Radio Signal Locate Detects long-range radio signals as they travel along buried cables and pipes
Small Diameter Locate Frequency Use the Genny4 to find and locate smaller diameter cables such as those found in street lights, or telecom wires
eCert Remote Calibration Validation Connect the CAT4 to PC and use C.A.T manager software to connect over the internet to Radiodetection for calibration validation (may incur extra costs)
Dynamic Overload Protection Filters out interference caused by high voltage power cables to protect from overloads and to ensure tracing accuracy
Depth Determination Gives an estimate to the depth of the buried utility - -
StrikeAlert Warns you quickly when shallow buried utilities are detected Optional Optional Optional Optional
Data Acquisition Capable of storing detection data for further analysis at a later date on PC - -
Service Due Indication The CAT4 will alert you when it's due for calibration/service - -
Swing Warning Warns you when the CAT4 is swung out of its detection range - -
CALSAFE When enabled, units can be set to automatically deactivate on expiry of calibration - - Optional Optional
