Fisher TW 6 Box Metal Detector

Electric power companies and others use this equipment to locate cable and wire, pipes, buried lines and other utilities. This two box metal detector is one of the Fishers most popular products. To increase the instruments sensitivity, Fisher engineers removed all unnecessary metallic parts on the TW-6, replacing them with durable ABS molded plastic. The device has a stereo jack for use with external headphones.

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
