Simplifying Use

  • Ease of Use – The locator requires minimal adjustment to locate services. Removing the sensitivity control also ensures detectable services cannot be missed where the user reduces sensitivity too much.
  • In-built Self Test – A quick check can easily be performed by staff or users to ensure units are working correctly. This can be carried out when off-hiring locators or handing over to users for the first time.
  • Signal Strength Indication (SSI) – features numeric signal strength readout, specifically designed for easy cable identification.
  • Hazard Zone – Alert the user to shallow services within 30cm of the locator. This can enable users to change their method of breaking ground and prevent cable strikes.

Leica DD120 buried utility locator, (60Hz) mains power  region Detection in Auto, Power, Radio and Transmitter modes.  Features Hazard Zone, shallow service and depth estimation  when used in conjunction with a signal transmitter or sonde.
