A heads up to those that are shopping for a new gps unit. I stopped in to buy a map 76 and there was the new 'S' version sitting on the shelf. They tripled the memory capacity, put in an electronic compass, a barometric altimeter, and retained all the original features of the 76. They also lighten the color of the casing. I had to fork out an extra c-note for it but it is one cool devise if your in the market. Very user friendly as well as floats!
