Cat & Genny (Locators)
The CAT (Cable Avoidance Tool) is the handheld locator that detects buried cables and pipes. Used with a Genny, it locates and traces specific services so you can dig safely. Models range from the Radiodetection CAT4 and C.Scope CXL to the Leica DD and ULTRA, with options for depth readout, StrikeAlert and data logging.
Buy new or refurbished, or take a calibrated unit on CAT and Genny hire. For non-metallic pipes add a sonde; for buried ferrous objects see magnetic locators. Choosing a model?

Cat and Genny FAQs
What is a Cat and Genny?
A CAT (Cable Avoidance Tool) is a handheld locator that detects buried cables and pipes. The Genny is its signal generator: it applies a traceable signal to a specific service so the CAT can follow it. Together they are the standard kit for avoiding cable strikes before you dig.
How much does a Cat and Genny cost?
Refurbished CAT4 & Genny4 kits typically run £695–£925, calibrated and under warranty. New CAT4 & Genny4 kits start at around £1,128. A refurbished standalone CAT starts near £365, and hire starts at £40 a week.
Should I buy new or refurbished?
A refurbished unit performs identically on site — each one is inspected, serviced, calibrated and warrantied — so for most users it is the better-value buy. Choose new if you want the full manufacturer warranty and the latest revision. The trade-offs are covered in refurbished vs new CAT4.
