Product Description
Add depth to your chartplotter view with the GSD 20 series remote sounders. The GSD 21, powerful analog sonar, Garmin's first digital sonar, is robust unit designed to operate with stand-alone chartplotters or integrate with the Garmin CANet and Marine Networks.The GSD 21 is a black-box sounder that provides fast Ultrascroll displays and 500-watt (RMS) sounder capability to 2000 series and 292/392/492 series chartplotters featuring the Garmin CANet bus. The GSD 21 will work with a serial connection to other Garmin plotters without the CANet connection, but will not offer Ultrascroll capability. The unit's all-new, high-dynamic range analog sonar receiver provides exceptional performance in water as shallow as one foot on down to depths of 1500 feet. It connects to a dual frequency transducer (50/200 kHz) for deep-water performance or a single frequency, dual beam width transducer (narrow/wide) for operation in shallow fresh water as well as deeper water. It provides 500 W transmit power with dual frequency transducer or 400 W with dual beam width transducer.

GArmin GSD 21 Remote Sounder September 1, 2008
I have Garmin products on both my boats and all three of my trucks/car. As usual the performance with Garmin is superb. Easy installation required one call to the Garmin Tech Dept. Their Tech Dept. is by far the most caring and concerned Tech people I have ever run into. I have it on my flats boat and ventured out in the ocean on a very calm day. The product gave excellant "coverage" on reading the bottom in water up to 300 feet. Here in South Florida most of my boating/fishing is in shallow salt water. I do fish off it for Bass in Lake lanier, Ga and Deep water lakes in Texas. Performed flawlessly. The vision chart is the icing on the cake. I still can not beleive all it does for navigating and the different views of the bottom. I just refitted my Bertram with two 5208's and Garmin radar. Couldn't be happier with ease of installation and performance. Awaiting the release of their new autopilot. I won't buy any other equipment but Garmin products. I am talking with over 10 years using their products both on the water and on land.
