Often used during construction and groundworks, CAT and Genny are a two-piece electronic system used to locate and identify buried services. Their use minimises the risk of any potential service strikes. Strikes can result in severe injuries, fatalities and extensive costs in damage.

This CAT and Genny training course provides comprehensive theoretical instruction on how to locate, trace and identify buried services and prevent service strikes, in line with key health and safety requirements and guidance including HSG47. Taking our training will support you in keeping yourself and those around you safe and reducing the risk of harm. Practical competence must be demonstrated separately through hands-on training and assessment.

What you'll learn

By the end of this course, you will be able to: 

  • Understand how to identify common buried services, the risks associated with service strikes and the checks required before excavation begins.
  • Explain how CAT equipment is used to locate and identify buried services, including the purpose and limitations of Power, Radio, Genny and Avoidance modes.
  • Know how Genny equipment, signal clamps, sondes and tracing methods are used to trace buried services and improve detection reliability.
  • Understand safe scanning, pinpointing and depth-estimating principles while recognising the limitations of locating equipment.
  • Know how to follow key health and safety guidance to help prevent service strikes and reduce the risk of injury, damage and disruption.

Training you can trust

Why take this course?

Tens of thousands of underground utility strikes occur each year and can lead to severe injuries, fatalities, service disruption and extensive costs in damage. Striking buried electricity cables, gas pipes, water mains, sewers or communication services can cause electrocution, fires, explosions, flooding and other serious consequences. Appropriate training is therefore essential for anyone who needs to locate, trace or identify buried services before excavation

This CAT and Genny course explains how to locate, trace and identify buried services using plans, visual inspections and locating equipment. The training supports safe excavation and helps reduce the risk of harm, costly repairs and project delays. Practical competence must be demonstrated separately through hands-on training and assessment.

Module 1: Introduction to Underground Services

This module introduces common buried services, the risks associated with utility strikes and the checks required before excavation. It explains how plans, visual inspections, CAT and Genny equipment, sondes and trial holes are used to locate and identify services, and covers PUWER, Permits to Dig, HSG47, safe excavation and emergency procedures.

Module 2: Understanding Cable Avoidance Tools (CATs)

This module explains how manual and automatic CAT equipment works and how electromagnetic signals are used to locate buried services. It covers AC and DC, Power, Radio, Genny and Avoidance modes, common detection limitations, safety alerts, calibration and health checks, visual inspections, GPS and data logging.

Module 3: Understanding the Genny

This module explains how Genny and transmitter equipment applies traceable signals to buried services. It covers common frequencies and the induction, nulling, direct connection and signal clamp methods, as well as using sondes and conductive tracing reels to trace non-metallic services.

Module 4: Application

This module brings locating and tracing principles together in practical examples. It explores operator, equipment, service and environmental limitations, how to interpret signal strength and tone, best-practice scanning and pinpointing techniques, manual and automatic CAT operation, locating sondes and estimating service depth.

Once you have completed all of the online training material, you will be able to take the online assessment. The assessment consists of 15 multiple choice questions with a pass mark of 80%. The answers are marked instantly so you will know whether you have passed as soon as you finish.

If you don’t pass the assessment you can review the course material and take the assessment again as many times as necessary at no extra charge.

This awareness-level course is aimed at all those involved in commissioning, planning, managing and carrying out work on or near underground services. It is specifically suitable for:

  • Operatives
  • Supervisors and Managers
  • Safety Officers
  • Civil Engineers and Technicians
  • Utility Workers
  • Construction Trainees
  • Organisations overseeing excavation work and any personnel responsible for ground-breaking activities

It is suitable for anyone who needs an awareness level understanding of CAT and Genny work. It is not suitable for those who need accredited training (accredited such as by NPORS).
