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.
