Upon completion of the course, participants will receive comprehensive revision materials to reinforce key concepts covered during the training.

Introduction to CAT and Genny Training

CAT and Genny , also referred to as CAT & Genny or CAT and Genny Training, are essential tools used in the construction and utility sectors to help locate and avoid underground cables and pipes during excavation works. CAT, which stands for Cable Avoidance Tool, is designed to detect signals naturally emitted by metallic services like electrical cables. Meanwhile, the Genny, short for Signal Generator, is used alongside the CAT to apply a signal to underground utilities that do not naturally emit detectable signals, such as telecoms or fibre .
Understanding how to operate these tools is crucial for anyone involved in excavation. Proper use of CAT and Genny can prevent costly and dangerous errors, such as accidentally cutting through power lines or water pipes. The training not only focuses on how to use these devices effectively but also covers the best practices for scanning different types of terrain and interpreting the signals received. This ensures that workers can conduct their tasks safely and efficiently, minimising the risk of disruption and damage to underground services.

What Is CAT and Genny Training?

CAT and Genny Training provides comprehensive instruction on using Cable Avoidance Tools (CAT) and Signal Generators (Genny) to locate underground utilities safely.

    Use the Genny’s induction mode when direct connections are not possible. Ensure the Genny is placed on the ground vertically for optimal signal transmission.

How to Use the CAT and Genny to Find Hidden Wires and Pipes

Getting Ready:

  • Check the Tools: Make sure the CAT and Genny are ready to use and have full batteries.
  • Set Up the Genny: Pick the right sound for the Genny to use so it can find wires or pipes under the ground. If you can, connect the Genny to the pipe or wire with a special wire.

Using the Genny:

  • Stand it on the Ground: Put the Genny on the ground where you think there might be something hidden. Turn it on to send a beep into the ground.
  • Connect it for Better Finding: Sometimes, you connect the Genny to something like a pipe for a clearer beep.

Using the CAT:

  • Start with Power Mode: Turn on the CAT and use the power mode to find beeps from wires that are on.
  • Try Radio Mode: Next, switch to radio mode to hear beeps from metal things like pipes.
    Finally, Use Genny Signal Mode: Use this mode to hear the special beeps from your Genny to find hidden stuff like plastic pipes.

How to Look Properly:

  • Move Slowly: Walk slowly with the CAT over the area. If you move too fast, you might miss some beeps.
  • Check in a Cross Pattern: First walk in one direction and then the other direction to make sure you cover all the area.

Understanding What You Hear:

  • Listen to the Beeps: A loud beep means you are close to a wire or pipe. If the beep sounds the same as you move, it probably means you found a wire or pipe.

Staying Safe:

  • Look Before You Dig: Always check by looking in the hole to make sure what the CAT and Genny found before you start digging.
  • Keep the Tools Working Well: Make sure your tools are working right by checking them often.
  • 500 mm from utilities; Always use insulated digging tools when close to underground utilities
