Metal detector Fisher TW-6

Detecting large metal objects, cables and pipes

The Fisher TW-6 metal detector is based on an invention by Fisher Research Laboratory Inc. which the company did in 1931. The characteristic of the TW-6 is that the transmitting and receiving coils are separated, unlike most other metal detectors in which both coils are integrated. This invention makes it possible to locate deep metal objects such as oil tanks, manhole covers, metal pipes and cables when there is no “starting point” to which a transmitter can be connected. One can locate in three different ways: Method A: with the transmitter and receiver attached to the carrying handle, making it work like a metal detector. Method B: place the transmitter above ground above the pipe and use the receiver to pick up and track the signal. Method C: when there is a The “starting point” is to connect the transmitter directly to the cable or pipe and pick up and follow the signal with the receiver.
