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.
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. 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.
