Leica DA transmitters

DA transmitter designed to work with the DD locator family

The Leica DA signal transmitters apply a signal onto underground cables or pipes that may not carry a detectable signal. The Leica DD SMART cable locators can then be used to locate the signal from the Leica DD signal transmitter. The DA signal transmitters are compact, robust and easy-to-use. The have been designed in conjunction with the DD SMART cable locators to easily and accurately avoid, trace or locate buried cables and pipes.

  • To improve the detection success.
  • To trace the route of a utility.
  • To make a depth or current measurement.
