I just received a case for my Garmin 76CSx from Foarm Inc., of Santa Barbara, Calif. It's really well made, it cushions the GPS well and it's claimed to float. Can't wait to use it on my new (1979) M17, "Orli," which I hope to get into the water within a month or so. Not only that, the customer service is incredible. They actually made one up for me in a color I couldn't find on Amazon.com. I spoke at length to one of the owners. I have no connection with this company except that I am now a very happy customer. Online at http://www.foarm.com/. The case cost about $27, including shipping. Dan Richman Shoreline, WA
