My brother and I are going on a long Alaska rafting trip. I am intent on taking a Garmin hand-held with either Alaska topo or the new Alaska Hunting software. My bother is intent on taking his iPad Mini that has built in GPS reception. He has also purchased a waterproof case for it.
Has anyone used an iPad for GPS function in the wilderness (raft trip or otherwise) that can give me some pros/cons of using the iPad vs. Garmin for GPS functions? The Garmin will either be the floating 78 model, but I may go with the 600 series for the much crisper and larger screen.
