GArmin GSD 21 Remote Sounder, September 1, 2008
This review is from: Garmin GSD 21 Remote Sounder (Electronics)
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.
