Fisher TW-6 Pipe & Cable Locator

Item:12-1020
Find underground pipes, cables, manhole covers, vaults, & other metallic objects

Product Description

*IMPORTANT - The rod (shown in 3rd image) is not included, must be ordered separately*

The Model TW-6 "Two-Box" metal detector finds underground pipes, cables, manhole covers, vaults, valve boxes and other metallic objects. Like earlier models, the TW-6 is used primarily by water departments, telephone companies, power companies, gas companies and petroleum pipeline companies when making repairs and rearranging lines. The TW-6 shows where to dig, as well as where NOT to dig, an important consideration when working near gas lines. To increase the instrument’s sensitivity, Fisher engineers removed all unnecessary metallic parts on the TW-6, replacing them with durable ABS molded plastic. Newly designed coil windings, completely upgraded electronics and nonmetallic parts have boosted the tracing distance of the TW-6 by 50-100 percent.

With the TW-6 longer tracing distances, which used to require expensive high-powered fault locator/tracers, can now be accomplished economically. In the Fisher tradition, the TW-6 is affordable, tough, and simple to use while providing maximum performance. A two year limited warranty comes standard with the unit.

The TW-6 Performs 3 Different Searches:

  1. Conductive Tracing: This is the preferred method for tracing because the Transmitter makes a direct physical hookup with the line to be traced. Plug the TW-6 Ground Plate Assembly into the Transmitter with one wire going to an alligator clamp that is attached to the pipe, non-energized wire or conduit.  This concentrates the signal on the known line to be traced, and there is less chance of the signal being induced to a nearby or adjacent line. Tracing distances are increased 25-50% over the Inductive method. Nonmetallic pipes may be traced Conductively if the Ground Plate Assembly is attached to a plumber’s "snake" or electrician’s "fish tape" running inside the pipe.

  2. Inductive Tracing: When one point of an underground linear conductor (such as a pipe or cable) is known, place the Transmitter Box of the TW-6 over it and trace in either direction. Walk out the path of the line and swing the TW-6 Receiver Box left and right over the line while listening for the audio signal tone. As you walk away from the Transmitter Box, tracing farther down the line, the Transmitter signal will become faint, but the Transmitter Box can be moved closer to you so that tracing can continue to the end of the line.

  3. Inductive Locating: Using a 4’ handle, position the Transmitter Box behind while the Receiver Box is ahead. Walk a grid pattern to discover the location of buried metallic objects. Watch the meter on the TW-6 Transmitter Box and listen for the signal tone to discover the location of a metallic object, such as a pipe, cable or vault box. Mark the pavement with chalk for each signal location. Soon a pattern will emerge that shows the location of underground linear objects, such as pipes and cables, or nonlinear items, such as a buried manhole cover.

  • Affordable, tough, and simple to use
  • Noise cancelling circuitry eliminates power line interference
  • Finds underground pipes, cables, manhole covers, vaults, valve boxes and other metallic objects
  • Unlike other units that use a separate transmitter and receiver, the TW-6, when mounted on the handle, can conduct “blind” searches of an area to locate an underground pipe or cable where the starting point is unknown
