Garmin GSD 22 Digital Remote Sounder

The GSD22 is a dual frequency, 1 kW/500W rms (dependent on transducer), direct sampling, Garmin Marine Network enabled, black box sounder. The unit will also have serial connectivity for Garmin non-network chartplotters. The exciting additions are a new direct sampling analog to digital sonar receiver that will provide exceptional target separation because of dynamic filter adjustments, better rejection of other fishfinder cross talk, an increased transmit ping rate, and a new transmitter capable of 1kW. The unit will also utilize the new 'Transducer ID' feature from Airmar on 1kW or greater transducers. The data available from Transducer ID will allow the receiver to automatically adjust the sounder performance to the varied characteristics of the different models of phased array 1 kW transducers.

The advantages of the GSD 22 over current Garmin products are: Network compatibility, 1 kW for deeper water(5000ft)/bigger boat operation, Better rejection of interference from other fishfinders, Improved cavitation noise rejection, Improved high speed performance, Excellent target separation because signal filtering can be tailored to depth and conditions, Power - 1kW / 500W (RMS), Frequency - 50/200 kHz, Voltage - 10-35 V, Max Rep Rate - 35 ms, LED - Monitor system status.
