Ping Rate of an Echo-sounder

The ping rate is the frequency with which an ultrasonic pulse is sent to the bottom by an echo sounder through the transducer.

Ping is the cycle that a transducer performs when it sends an ultrasonic pulse to the bottom and from the same received after it has bounced off the bottom.

Not to be confused with the transmission frequency of an fishfinder, which only indicates the oscillation frequency of the ultrasonic pulse.

The ping rate, commonly expressed in seconds, indicates how many pings the transducer (in turn guided by the fishfinder) can make in a second.

The higher the ping rate, the easier it will be for the fishfinder to orient itself and show details. On the other hand, a high ping rate may overcharge the processor with the data to be analysed.
