MLFP-1 Multi 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 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. Different broadcast frequencies are available for pingers, allowing multiple to be deployed in the same geographic region without interfering with one another. The diver tunes his pinger receiver to the targeted pinger's frequency, and the receiver directs him directly to it. These low-frequency acoustic pingers have a range of 3 to 6 miles, whereas ordinary mid-frequency (30 to 40 kHz) pingers have a range of several thousand feet.
The operator may adjust the number of pulses per second, the duration of each pulse, and the output power for the acoustic pingers manufactured by Fishers. The operator is able to vary the distance at which pingers can be detected by altering the pulse duration and output strength. Before deployment, the operator can choose the transmission frequency for the MLFP-1. These characteristics render the pingers very adaptable and the best option for practically any application.
Optional PC Software enables the user of a laptop to fine-tune the variable parameters, including the selection of delayed start (from a minute to a 365-day delay start). The pingers are powered by regular alkaline batteries that, depending on output power and pulse selection, last from a few weeks to several months. Extended Functioning Life housing and Very Long Duration housing (hold more batteries) are available, which greatly prolong the operating time.
Features
The pinger can be engaged automatically when submerged in water or manually through the circuit board. Our special, two-year, UNCONDITIONAL guarantee covers all Fishers pingers.

Single Low-Frequency Pinger (SLFP-1) and Multi Low-Frequency Pinger are members of JW Fisher's line of commercial grade low-frequency acoustic pingers (MLFP-1). The SLFP-1 is offered in 11-16 kHz in 1 kHz increments, one of which must be specified at the time of purchase. The MLFP-1 allows the user to pick frequencies between 11 and 16 kHz in 500 Hz increments. Before deploying the pinger, the operator chooses among eleven distinct frequencies.
