Product Description

Fisher TW-82 Digital Line Tracer
Easy-to-Use Single Frequency Pipe and Cable Locator

The Fisher TW-82 is an easy-to-use single frequency pipe and cable locator. Its ultra-fast target response ensures fast accurate tracing, while eliminating unnecessary user controls. TW-82 transmitter’s conductive trace load current display indicates your connection quality quickly and clearly. The locator uses automatic load impendence matching to adjust output for full-rated power over a variety of utility types and ground conditions.

View continuous readouts on the Fisher TW-82’s large LCD screen, including utility direction, orientation relative to the line, target depth, signal current and battery condition. The locator is weatherproof and impact-resistant, and features sealed, thick-wall, injection-molded construction.

Setting a new standard of performance in high frequency line tracing! The TW82 is an active locating line tracer. There are three locating methods that an operator can use to trace a utility.

  1. The conductive method is the preferred method, as a strong signal is transmitted directly through the intended target.
  2. The inductive method is the easiest method to use, but may not yield the best results. When a direct connection is not available, but the operator has some knowledge of where one point of the utility may be, the operator can place the Transmitter on the ground over the utility.
  3. The third method of active locating involves using the coupling clamp; the coupling clamp is an optional accessory. The coupling clamp is only to be used on electrical or communication lines that are in service, not pipes or tracer wires. The coupling clamp is used when the utility is exposed, but a direct connection is not available. The clamp jaws are opened and placed around the utility. The clamp does not make a direct connection to the utility.
