As crew on sailboats, I have no way to mount my GPS as I am on a different boat all the time. I just got a Garmin GPSMAP 78cs and it is a wonderful piece of equipment. I know it floats and its waterproof, but when I was searching on ebay for the GPS, I came across a case that I just had to have. The GizzMoVest Case protects the unit and is an accessory that is made with great quality. I wanted something so I could just throw the unit in my bag and have it ready when I need it. This case is made in USA and you can tell the pride in workmanship. Just check out GizzMoVest for more information on this awesome accessory
