The Leica DD120 and DD130 Pipe and Cable Locators (part numbers DD120 and DD130) detect the position of buried cables and pipes before excavation. Striking an unknown underground service during digging risks operator injury, damage to the asset and the costs that follow, so locating utilities first is a core safety step on construction sites.

Both locators offer power, radio and auto modes and automatic pinpointing, with a paired transmitter applying a traceable signal at 33kHz or 8kHz to lines that may not otherwise carry a detectable signal. They accept power at 50Hz or 60Hz, detect radio in the 15kHz to 60kHz band, and include a Good-to-Go health check and start-up test. Each unit is IP54 rated for protection from dust and water, operates from -20 degrees C to +50 degrees C, runs on 6 x LR6 (AA) alkaline batteries for around 15 hours, and weighs 2.7kg with batteries. Depth accuracy is 10 percent.

The two models differ in trace range and depth. The DD120 transmits at 33kHz and 8kHz with line and sonde depth detection from 0.3m to 3m. The DD130 adds 512Hz and 640Hz frequencies for extended tracing and increases sonde detection up to 9.99m, while signal current measurement helps confirm the right line is being followed. Both are supplied by BAMR, South Africa's authorised distributor.
