This black-box sounder connects to your chartplotter over the Garmin Marine network to provide high-speed data returns and super-crisp detail. Once connected, any plotter on the network can view the 22's detailed sonar data and overlay it on the map page. You can also use the GSD 22 with Garmin's CANet to connect to non-network chartplotters.
The GSD 22's digital design provides extraordinary target definition and deep water performance and allows it to transmit at up to 2 kW, depending on your transducer. The 22 also adjust gain and transmit power automatically to optimize the returns for shallow water as well. It can connect to a dual-frequency transducer and works with everything from a standard 500 watt transom-mount transducer to a heavy-duty 2 kW thru-hull or in-hull transducer and can reach a depth of up to 5,000 feet.
