IMO the gps units with 1 central toggle button for all functions are not as user friendly as the ones with multiple buttons (gets old toggling through multiple pages to reach the one you want). My Rhino has a central toggle and my buddy has the 60csx with multiple buttons which is much faster getting to the function you desire. The 60csx picked up satelites better than my Rhino standing side by side in the brush and my rhino was 5 years newer and more expensive. My 2 way radio built into the Rhino doesn't get out as good as my regular 2 way hand held radios. I own the Rhino and it works, but I would buy something different next time. Also on my Rhino every time you turn it on you have to go to the radio function and shut it off which helps concerve battery life and it is anoying if you power up and are trying to be quiet but all the sudden you here the radio I keep it turned all the way down for this reason. The altimeter on my Rhino is accurate and I also purchased the Terrain Navigator program. It tracks in real time on the maps when hooked to your PC, tracks can be easily sent to other programs or people and it even synchronizes with google earth which you can send tracks and such to. Makes it lots funner to own a gps when paired with a program like Terrain Navigator.Lastly, I have the rechargeable battery pack for my Rhino (slightly more bulky), but have been happy with the battery life.
Garmin Rhino with out a doubt... its nice to be able to see where your hunting partners are in case of injury or they get an animal down and need help.
