JW FISHERS MFT-1 Transponder Metal Detector

JW Fishers acoustic sonar transponder makes it quick and easy to relocate an underwater site or piece of equipment. The sonar transponder is attached to an underwater location where it sits quietly listening for a coded signal from a acoustic sonar interrogator. When a diver, equipped with a sonar interrogator, points the interrogator in the direction of the transponder, the transponder sends out a coded return signal that is picked up by the acoustic sonar interrogator. The interrogator displays the distance to the transponder (in feet or meters), and a compass displays the heading to the transponder. The diver can follow the signal directly to the target. The acoustic sonar transponder can transmit any one of sixty (60) different frequencies (operator selectable), so many can be deployed in the same general area without interfering with each other. The diver sets the acoustic sonar interrogator to the frequency of the acoustic transponder and is guided directly to it. The MFT-1 multi frequency transponder has a range of over 3,000 feet.

The standard frequencies are: 20kHz to 50kHz in 500Hz steps (special frequencies are also available). The MFT-1 can be automatically activated when put in the water or manually activated with a switch before deployment. Many MFT-1 can be deployed in the same general area, each transmitting a different frequency. A diver using the DHI-1 diver held interrogator can pinpoint the exact location of each MFT-1 transponder.
