Turn Any Buried Line Into a Traceable Signal.
Passive detection finds live cables. The Leica DA175 is what you reach for when you need to find everything else — dead cables, de-energized mains, gas mains, and metallic pipes with no current running through them. Connect to any metallic service or use induction mode and the DD120 or DD130 locates it, measures its depth, and traces its route.
Six operating frequencies including 512Hz and 640Hz for long-distance tracing. 1 Watt output in both induction and direct connection modes. IP67 waterproof whether open or closed. The standard transmitter for the entire DD series — compatible with DD120 and DD130.
Key Features
1 Watt — Induction & Connection
Maximum 1-Watt output in both modes. Place on ground for induction, or connect directly via cable, clamp, or property plug for the strongest possible signal on the target line.
512Hz & 640Hz — Long Distance
Low-frequency modes for tracing long cable runs where higher frequencies lose strength. Essential for large-site utility surveys and municipal work.
33kHz & 8kHz Active Tracing
Mid-range frequencies for general utility tracing. 33kHz for most applications, 8kHz for better penetration in difficult soil conditions.
IP65 Open / IP67 Closed
Protected against water jets when open, fully waterproof when closed. Built for real job site conditions in all weather.
LED Feedback Panel
Battery, connection mode, frequency, and power output all shown via LED indicators. Audio tone confirms connection quality in the field without looking at the unit.
15-Hour Battery Life
4× D-cell alkaline batteries. Available everywhere, no charging required. Carry a spare set and you're covered for multiple days on-site.

Signal Transmitter Connection Guide
Direct connection, inductive coupling, and best practices for getting a clean signal on the target utility line. Essential viewing before your first field use.
Using the DA175 with the DD120 Locator
Frequency selection, depth estimation, and route tracing with the DA175 and DD120. The same workflow applies to the DD130.
Inspecting a Manhole — Sonde Locating
Using a sonde through a manhole for non-metallic pipe and drain tracing. The DA175 drives the locating signal through the sonde in active mode.
Inspecting a Manhole — Trace Rod
Push a Trace Rod through non-metallic services and locate from the surface. The DA175 transmitter drives the signal.
