FISHER TW82 Digital Line Tracer

The Fisher Labs TW82 Single Frequency Digital Underground Line Tracer is an easy-to-use single frequency, one-button pipe and cable locating system designed to trace all conductive lines including pipes, cables and conductive electrical lines. Its ultra-fast target response ensures fast and accurate locating. The transmitter utilizes automatic load impedance matching to adjust output signal for best power output for the ground conditions. The TW82 is weatherproof and impact-resistant, and features sealed, thick-wall, injection-molded construction.

The TW82 is used to locate and trace buried utilities using three tracing methods: conductive, inductive, and via coupling clamp.The conductive method uses the accompanying transmitter to energize the buried utility by making a direct electrical connection to it with conductive tracing cables. In most cases, this method sets up the strongest magnetic field for the receiver to sense above ground. The inductive method is ideal for when a direct physical connection to the utility is unavailable. The utility may be energized indirectly by magnetically coupling an energizing current from the accompanying transmitter. The coupling clamp method is for use when a utility may be exposed, but does not provide a direct connection for the conductive tracing cables. The accessory coupling clamp can be clamped around the exposed utility to magnetically couple an energizing current from the accompanying transmitter into the utility.
