JW Fishers MFP-1 Multi Mid-Frequency Pingers, SHIPS FREE, $1070.72

A quick and easy way to relocate an underwater site

JW Fishers acoustic pingers make it quick and easy to relocate an underwater site or piece of equipment. The pinger is attached to an underwater location where it continuously transmits a sonar signal. A diver equipped with a pinger receiver can detect the acoustic signal and follow it directly to the pinger. Pingers are available with different transmit frequencies so several can be deployed in the same general area without interfering with each other. The diver sets the pinger receiver to the desired frequency and is guided directly to the pinger.

Specify operating frequency: Select 22,26,30 or 37.5kHz at time of order (custom frequencies also available)
