Why This Course Exists
Why our CAT and Genny course starts with the Genny
Most cable avoidance courses teach operatives to switch the CAT on and walk. They learn what the beep means, but not why the signal behaves differently in wet or disturbed ground, what happens near a joint, or why a passive Power reading misleads. The result is certificates handed out without changing how operatives work on site.
CAT stands for Cable Avoidance Tool: a passive receiver, not a safety guarantee on its own. So we teach the Genny first: apply a known signal, trace it across the site, and verify it before trusting passive readings. A proper CAT and Genny scan starts with the Genny. That order is why we say Genny and CAT, and 21 years of post-strike data points the same way: most preventable strikes happen when operatives skip the Genny.
It changes behaviour. Operatives trained by Sygma use the Genny 70 to 80% more, measured through locator data downloads.
Course Content
What the CAT and Genny course covers
Classroom theory, then practical work on site with the Genny and CAT, locating real buried services and cross-checking them against the plans. Many clients know this course as cable avoidance training. The syllabus below is the same whichever badge you choose.
Classroom: Theory
The full technical and regulatory context
- ›HSG47 and the duties of clients, designers and contractors
- ›Buried service plans (STATS) and their limits
- ›How a cable avoidance tool works, and where it stops working
- ›All four modes: Power, Radio, Genny and Avoidance
- ›Reading the signal: joints, direction changes and depth
- ›Pre-use checks, calibration and CAT Manager data
Site-Based: Practical
Every principle proved on real underground services
- ›Reading service plans to plan the survey
- ›Applying a signal by direct connection, the clamp and induction
- ›All four modes, with the Genny first throughout
- ›Problem services: street lighting, LV and small comms
- ›A structured CAT and Genny scan across the working area before excavation starts
- ›Individual practical assessment against a documented standard

Also Known As
Cable avoidance training: the same course
Cable avoidance training is the name many clients and principal contractors use for this course. It is the same day, the same syllabus and the same assessment, whichever certificate you choose: Sygma's own, EUSR Cat 1 or ProQual.
The CAT is the cable avoidance tool itself, and using it properly is a trained skill, not a matter of switching it on and sweeping. The course covers the tool in depth: the passive Power and Radio modes and what each can and cannot detect, why a passive sweep alone never guarantees a clear dig area, and the pre-use checks that confirm the tool is working before every use. If your operatives already carry a CAT but have never had formal cable avoidance tool training, this is the course that turns the box in the van into a strike-prevention instrument.
Formats Available
CAT and Genny course formats
Every format is the same cable avoidance course and the same assessment. EUSR CAT1 and ProQual CAT1 certificates last 3 years, and ProQual CAT1 Plus assesses the Genny-first method formally. Sygma is a CITB Approved Training Organisation, so levy-paying employers may be able to get funding through the CITB Employer Network.
| Format | Duration | Max Delegates | Assessment |
|---|---|---|---|
| One-day in-house (certified) | 1 day | 8 | Written + practical |
| One-day EUSR CAT1 (accredited) | 1 day | 8 | Written + practical |
| One-day ProQual CAT1 (accredited) | 1 day | 8 | Written + practical |
| Two-day in-house (certified) | 2 days | 8 | Written + practical |
| Two-day ProQual CAT1 Plus (accredited) | 2 days | 8 | Written + practical |
| Two-day split - 3 months apart (certified) | Day 1 + Day 2 | 8 | Day 1 training, Day 2 assessment |
The two-day split puts three months between the training day and the assessed day, so the method beds in on real work first.

Common Questions
CAT and Genny training: common questions
What is CAT and Genny training?
The course teaches operatives to use a cable avoidance tool (CAT) and signal generator (Genny) to find underground services before excavation. Sygma teaches a Genny-First methodology and offers EUSR CAT1, ProQual CAT1, and in-house certification routes.
How long does a CAT and Genny course take?
One day, 08:30 to about 15:00, with a written and practical assessment. Two-day formats are available on site: they split classroom and site work, or add the ProQual CAT1 Plus Genny-First assessment on day two.
Can CAT and Genny training be done online?
Classroom theory can be delivered online for awareness and refreshers: Sygma offers a CAT4 HSG47 Awareness Online course for that. The full assessed qualification (EUSR CAT1 or ProQual CAT1) requires a real site practical and cannot be completed entirely online.
How much does a CAT and Genny course cost?
Open courses at our Wigan centre are from £121 per delegate. On site, it is one fixed price for your group of up to 8 delegates at your premises, travel included, with no hidden extras: contact us for a quote. Certificate fees (EUSR £34, ProQual £35) are charged per person on top of the course fee. CITB-levy employers may access funding via the CITB Employer Network.
Do you need to be trained to use a CAT scanner?
Yes. HSG47 requires anyone using cable and pipe locating equipment to be trained and competent. CAT scanner training is the same course as CAT and Genny training, since the CAT is the scanner. Most principal contractors and utility companies require a recognised qualification before allowing operatives to use locating equipment on site.
How long is the CAT and Genny qualification valid for?
EUSR CAT1 and ProQual CAT1 certificates are valid for 3 years. Sygma in-house certificates have no fixed expiry, but most employers require refresher training every 3 years.
Is EUSR CAT1 the same as EUS CAT1, or the same as CAT and Genny training?
EUSR CAT1 and EUS CAT1 are the same qualification. CAT and Genny training is the broader practical course; EUSR CAT1 is the specific accredited qualification many employers ask for. Booked as EUSR CAT and Genny training, it is this same course with the EUSR Cat 1 certificate. Sygma delivers both, plus ProQual CAT1 and ProQual CAT1 Plus.
Is cable avoidance training the same as CAT and Genny training?
Yes. Cable avoidance training and CAT and Genny training are the same course under two names the industry uses. Both teach operatives to find buried services before excavation with a cable avoidance tool (CAT) and a signal generator (Genny), and Sygma teaches the Genny first. Whichever name you search for, it is this course, this syllabus and this assessment.
Is cable avoidance training a legal requirement?
HSG47 and the CDM Regulations place a duty on employers to make sure anyone involved in excavation is competent in avoiding danger from underground services. No single law names a specific CAT and Genny certificate, but employers must be able to show their workforce has been properly trained, and most principal contractors and utility companies ask for a recognised qualification such as EUSR CAT1 or ProQual CAT1 before operatives go on site. Inadequate training can lead to enforcement action, fines and prosecution if a cable strike causes injury.
What equipment do our operatives need to bring?
Each operative should bring the Genny and CAT they use on site. Sygma provide Radiodetection CAT4 and Genny4 as backup if delegates do not have their own. Any manufacturer's locator is suitable, including Vivax-Metrotech vLoc, Leica DSX and Radiodetection RD8200 and RD8100. If equipment is shared, allow at least one locator per three delegates.
Can the course be tailored to our sites and risk profile?
Yes. On site, the course can take in your own permit to dig, your strike history and lessons learned, site-specific hazards, and your documentation and health and safety procedures. The QTS surface laid cables programme is an example of a course built around one customer's exact needs.
What delegates say

From 375 end-of-course feedback forms completed by delegates on our CAT and Genny courses since September 2026.
“From not previously having used a cat and genny, I learnt everything needed to use one on site safely and confidently. The trainer was friendly and informative”
“Trainer was insightful and clearly had a knowledge far beyond just teaching the course. Learned something about the CAT and Genny 10 years after first use.”
“Have attended numerous previous courses, this was the best in establishing good practice with clear reasoning.”
“Really appreciated the combo of class and practical work. Andy was great”
“Thank you, very good course and picked up some new tips that will help me and keep me safe in my job role”
“Great course and Steve brings much needed humour and great knowledge of subject matter making course enjoyable”
Regulation
CAT and Genny training and HSG47
HSG47 is the Health and Safety Executive's guidance on avoiding danger from underground services, and it sits behind all cable avoidance work. This course is built around it, and every delegate is assessed against it on real buried services. See our HSG47 Training page for what the guidance requires.
