JW Fishers Single Frequency Pinger SFP-1 Metal Detector
Acoustic Pingers Make it Quick and Easy to Relocate an Underwater Site or Piece of Equipment

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.

JW Fishers family of commercial grade pingers include both the Single Frequency Pinger (SFP1) and the Multifrequency Pinger (MFP1). The SFP1 is available in several frequencies one of which is specified at time of order (22, 32, 40, or 50kHz). The MFP1 has user selectable frequencies from 20 to 50 kHz in 500 Hz increments. The operator selects one of 60 different frequencies before deploying the pinger. Many pingers can be deployed in the same general area, each broadcasting at a different frequency. This enables a diver with a pinger receiver to pinpoint the exact location of each pinger without interference from the other pingers.

Fishers pingers are very flexible allowing the operator to select the number of pulses per second, the length of each pulse, and the output power. The length of each pulse and output power adjustments allow the operator to adjust the distance the pingers can be detected. With the MFP1 the transmission frequency can be selected by the operator before deployment. These features make the SFP1 and the MFP1 extremely versatile and the first choice for almost any application. Power for the pingers is supplied by two standard alkaline 9 volt batteries which last from a few days to many months, depending on output power and pulse selection. For long durations lithium batteries can be used. A longer housing is also available which holds six batteries to give 3 times the normal operating time. The pinger can be automatically activated when put in the water or manually activated with a switch.
