Cable Detector for Electricians UK Before Chasing or Routing
Answer first: The right cable detector for electricians uk is the one that marks wood, metal and live AC clearly enough that you pause before the drill bit commits.
Electricians already own proving tools; a wall scanner simply reduces blind chasing into unknown plasterboard runs.
Use buyer phrasing they already type: cable routing, chasing, live AC.
How to scan without false confidence
- Calibrate on a known clear patch when the tool requires it.
- Mark both edges, then find centre—do not trust a single beep.
- Re-scan after moving horizontally; conflicting signals mean open carefully.
- Never treat a scanner as a substitute for safe electrical proving.
