Leica DA175 1-Watt Signal Transmitter

Overview

The Leica DA175 is the professional-grade 1-watt signal transmitter designed for contractors, utility locators, and infrastructure professionals who need to reliably trace, locate, and map buried utilities. Whether you're working with dead cables, de-energized mains, gas lines, or metallic pipes with no active current, the DA175 provides the precise signal generation needed to confidently identify utility routes and depths using compatible Leica locators like the DD120, DD130, and DD300 Connect.

This compact, rugged transmitter delivers active locating capability across six operating frequencies, enabling both standard utility work and long-distance tracing applications. With 15-hour battery runtime, IP67 waterproof construction, and flexible connection modes—induction or direct clamp—the DA175 is built for job-site reliability in demanding field conditions.

Key Features

Powerful 1-Watt Output: The DA175 generates up to 1 watt of signal power in both induction and direct connection modes, ensuring strong, detectable signals even at depth and over extended distances.

Six Operating Frequencies: Choose from 33kHz, 8kHz, 512Hz, and 640Hz frequencies. The 512Hz and 640Hz frequencies are optimized for long-distance tracing, while 33kHz and 8kHz are ideal for standard utility identification and depth estimation work.

Dual Connection Modes: Operate in induction mode by placing the transmitter on the ground above utilities, or use direct connection mode with cable clamps and property plugs for hardwired signal injection. This flexibility adapts to any utility type and site condition.

Long-Life Battery: Four LR20 (D-cell) alkaline batteries provide up to 15 hours of continuous operation, minimizing downtime and battery swaps on multi-day locating jobs.

Waterproof Design: IP67 rating when closed and IP65 when open ensures the DA175 survives wet conditions, muddy work environments, and accidental submersion.

LED Status Display: Integrated LED indicators show battery level, operating mode, active frequency, and output status—giving you real-time feedback on transmitter performance and connection quality.

Audio Tone Confirmation: An audio tone confirms when a connection is established and signal quality is optimal, reducing guesswork and improving job accuracy.

Applications

The DA175 is essential for utility locating professionals who regularly encounter:

• Dead Cable Tracing: Trace and map non-energized electrical cables, power lines, and communication conduits.
• De-Energized Mains: Locate gas mains, water mains, and other utility lines with no active current.
• Metallic Pipes: Identify and route metal pipelines, steam lines, and industrial conduits.
• Depth Estimation: Use the DA175 with compatible locators to estimate burial depth and plan safe excavation.
• Route Mapping: Conduct comprehensive utility surveys to create accurate subsurface maps for construction, design, and safety planning.

Compatible with the Leica DD120, DD130, and DD300 Connect locators, the DA175 integrates seamlessly into established utility locating workflows.
