Fisher TW82 Digital Utility Line Tracer 82.175 kHz with Lateral Mode

Fisher TW82 82.175 kHz Digital Utility Line Tracer with Lateral Mode

The Fisher TW82 digital line tracer is designed for locating and tracing buried utility lines using a single 82.175 kHz frequency. Featuring both Normal and programmable Lateral modes, it supports conductive and inductive tracing for metallic pipes, cables, and tracer-wire-equipped plastic lines.

Precision 82.175 kHz Signal with Dual Tracing Modes

• Single frequency 82.175 kHz transmitter and receiver system
• Normal and programmable Lateral tracing modes
• Conductive tracing capability (2–8,000 ohms normal; 2–3,000 ohms high)
• Inductive tracing with 15 Vm² (normal) and 25 Vm² (high)
• Automatic depth and signal current measurement display

Integrated Guidance and Field-Ready Construction

The receiver provides real-time numeric signal strength, left/right guidance, azimuth indication, and over-target alerts for accurate line positioning. Housed in an IP65-rated enclosure, the TW82 operates in temperatures from -4°F to 140°F and is powered by D-cell batteries for extended field use.

Utility Locating Applications

• Tracing underground water and gas pipelines
• Locating buried electric and telecom cables
• Identifying service laterals branching from main lines
