Fisher TW-6 2-box Metal Detector

Find Underground Metallic Objects with Ease

The Model TW-6 “Two-Box” metal detector finds underground pipes, cables, manhole covers, vaults, valve boxes and other metallic objects. 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.

Easy Operation, Accurate Target Location

The TW-6 shows where to dig, as well as where NOT to dig. To increase the instrument’s sensitivity, Fisher engineers removed all unnecessary metallic parts on the TW-6, replacing them with durable ABS molded plastic. Coil windings are designed with completely upgraded electronics and nonmetallic parts have boosted the tracing distance of the TW-6. 

Classic Fisher Design

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. A Ground Rod Harness Assembly provides an efficient ground for conductive tracing. The Fisher TW-6 Pipe & Cable Locator has noise cancelling circuitry that eliminates power line interference. As industry leaders in pipe and cable locating equipment, Fisher has perfected the technology originally introduced in earlier models. 

Detailed Specifications:

• The Fisher TW-6 metal detector is the industry leading 2-box locator
• The Fisher TW-6 is excellent for blind searches
• Crystal controlled frequency in both transmitter and receiver increases tracing distance
• Unlike other units that use a separate transmitter and receiver, the Fisher TW-6 when mounted on the handle, can conduct "blind" searches of an area to locate an underground pipe or cable when the starting point is unknown
• VCO (Voltage Controlled Oscillator) gives a wider range of audio single to indicate the presence of metal. Even after the meter pegs, the audio signal goes much higher in pitch and volume
• Noise canceling circuitry eliminates power line interference
• The Fisher TW-6 is powered by 16 standard AA (penlight) batteries: eight in the transmitter and eight in the receiver
• The Fisher TW-6 metal detector weighs only 5.5 pounds
