Signal Generators (Gennys)

A signal generator, or Genny, applies a traceable signal to a buried cable or pipe so your CAT scanner can locate and follow that specific service. It is the only reliable way to find unloaded cables and to trace an individual line, by direct connection, signal clamp or induction.

We stock Gennys from Radiodetection, C.Scope and Leica, plus connection leads, clamps and accessories. Pair a Genny with your CAT for accurate locating; the method is in the 2026 cable avoidance guide and our accurate locating tips. Need kit for one job? See CAT and Genny hire.
