Summary: This is one of the best GPS units I own. Have the Map62s, Rino 650, Dakota 20, and now the Oregon 650t. My two favorite units are the Rino 650 and the Oregon 650t. Highly recommend it, but be careful that some units shutdown for no apparent reason just when your not paying attention. I'm on my second unit. Firmware upgrade should fix this. My first unit actually seemed to get worse... Also, the unit is a little heavy. The whole unit is really rugged.
Summary: If I were to purchase again I would get the 650 and buy 24K maps separately. The 100K maps do the job, but are short on many details. If you don't lock the screen, it will reset itself into anoying modes. I have done complete reset many times to recover from this. The belt clip if attached interferes with the camera. I used customer service to answer a question, and they were great!
Summary: I upgraded to this unit from a GPSMAP 62STC and am pleasantly surprised. The touch screen makes it MUCH easier to navigate through menus, the interface is intuitive and effective. I am waiting for Zagg to come out with one of their nice screen protectors for this unit, my only fear is scratching up the nice screen when I am using it on the trail.
Summary: This is the first time I'm using a hiking GPS. It's very much different than using a driving GPS. I recommend going for several short walks around your home to figure out the features and menu structure. I found it was very easy to create a waypoint, but very difficult to figure out how to delete it. However, once you figure it out, it's easy. I notice that if I put the unit in my pocket I need to remember to lock the screen beforehand.
