JW Fishers SLFP-1 Low Frequency Pinger

SLFP-1 Low Frequency Pinger by JW Fishers Underwater acoustic pingers are devices that emit acoustic signals. They are used to identify an underwater site or piece of equipment so that a returning diver equipped with a pinger receiver can pinpoint the exact location. Underwater devices that emit acoustic signals are known as acoustic pingers.They are used to mark an underwater site or piece of equipment so that a returning diver equipped with a pinger receiver can find the exact location. Multiple pingers can be deployed in the same geographical region without interfering with one another since multiple broadcast frequencies are available. The diver changes the frequency of his pinger receiver to that of the target pinger, and the receiver then directs him directly to it. These low-frequency acoustic pingers have a range of 3 to 6 miles, compared to a few thousand feet for standard mid-frequency (30 to 40 kHz) pingers. The operator may set the number of pulses per second, the duration
