A friend of mine wants a handheld Gps to use while fishing fresh water lakes and Florida flats. I use a Garmin 76 during my part time job of measuring crop land, have never used it for fishing or hunting.

Can y'all give some advice on what is a good unit for fishing. He wants one that's water proof, can be downloaded to his wifes' pc. Will tell him how fast he's moving when trolling, and if possible, can have programs added to it later. Also wants one that can be pluged into a cigarette liter to save on batteries, etc, etc,.

Any suggestions would be appreciated and I'll pass them on to him.

Thanks,
