Locator
Features
- Crystal controlled frequency in both transmitter and
receiver increases tracing distance 50-100 percent over earlier two-box
detectors.
- 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 when the
starting point is unknown.
- VCO (Voltage Controlled Oscillator) gives a wider range
of audio signal to indicate the presence of metal. Even after the meter
pegs, the audio signal goes much higher in pitch and volume.
- Noise cancelling circuitry eliminates power line
interference.
- Powered by 16 standard AA (penlight) bateries: eight in
the transmitter and eight in the receiver.
- Weights only 5 1/2 pounds.
Description
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 increases 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.
