The GSD 22 is a powerful remote sounder that plugs directly into the Garmin Marine Network for use with our network chartplotters, including the 2000/3000/4000/5000 Series displays — or into the Garmin CANet for use with the 292/392/492/430/440/530/540/535/545 series chartplotters. Ultrascroll technology keeps the display scrolling at live-action speeds, while the unit’s digital design and up to 2 kW of transmit power (depending on transducer used) provide extraordinary target definition and deep water performance. Transmit power and receiver gain automatically adjust to produce excellent shallow water performance as well. The GSD22 is dual frequency (200/50 kHz) and works with everything from a standard 500 W transom mount transducer to heavy-duty 2 kW thru-hull or in-hull transducers. Reaches depths to 5,000 feet.
