I bought a 62 as a backup to my 60 for the Yukon 1000 race last July. One was set to view course direction for next planned waypoint in compass view along with speed, the other in map view to show me what to expect after next. From my previous years experience on the Y1K I knew I wanted to navigate with both views simultaneously rather than to be constantly swapping views on a single unit and missing paddle strokes doing so.
I must say that I like the 60 overall much better, although if I had never seen the 60, then the 62 would be fine. Functions are roughly equivalent, especially for what I really need. The 62 has much more stuff that I'll never use. I also think it burns batteries faster than the 60.
But my biggest complaint is actually the stupid mounting method for the 62. The 60 has a nice clamp handlebar style mount that firmly grips a handlebar or canoe thwart. Since I paddle/train/race in several different canoes (except for the Yukon, the GPS's main function is just for monitoring and maintaining speed), changing the 60's mount is fast, easy and secure. However the only mount available for the 62 (from Garmin or from 3rd party) requires plastic cable ties to hold it in place, and it does not do that very well. With the 60 I can easily move the mount from one canoe to another with a stubby phillips screwdriver that I always keep in my PFD pocket. But the 62 requires a pair of cable nippers and an unending supply of plastic ties. Stupid. I'm glad I bought another 60csx at discount just before they completely disappeared. It remains in the box saved for if and when my current 60 dies.
The photos show both mounted side by side. Left photo also shows a SPOT (required by Y1K rules) in my almost empty food bin, and a book of 95 paper google earth maps showing planned course with 738 waypoints plotted and correlated to the GPS.
