Been using the Rino 650 for the last 5 rides. The touch screen is awesome. So easy to use. We have had to use the manual or you tube only a couple times to figure out how something works. We do turn the screen up to 80-100% backlit to see it better in the sun. The radio is awesome. Saves so many headaches especially early in the year when we are scouting out routes. Don't have to get every one turned around. I love the polling feature where I can see everyone in my group right on the GPS screen. One of our group is always running around by himself and I can track him just by looking at my screen. Also, the screen works great in the cold. We keep them in our pockets when not in use. I am going to try a radio mike like the ski patrollers and cops use. Just clip it to my shoulder so I don't have to pull the radio out each time to use it. Battery lasts 2 days if you shut it down at night.
