I was delighted to see the RINO models, as we found that carrying both a GPS and a separate radio while hunting was a real juggling act. This combination was an answer to prayers. I expect a significant number of my family and hunting friends will end up with these units. Some of the reviews mentioned problems with radio compatibility with the Motorola FRS units. We have six of the Motorola units and have had no problems between them and the Garmin. I have also, so far, not had problems with battery life, and have used the unit in all combinations of operation. One hopes these problems were isolated events.
I find the RINO's operation to be very intuitive, little or no reference to the manual was necessary (though I have now read the entire thing). The unit is certainly the easiest of all the various GPS units I've used. This one even picks up signal while in our house, something no other unit I've seen has done.
A factor I had never considered with other units is how well the machine fits/holds in the hand.
So far, in our short association, I'm both very impressed and pleased with the machine. I would recommend it highly.

June 03.
The RINO and I have now been together for a number of months. It continues to be an excellent tool.
In addressing the reports of battery life and radio reception, I feel it necessary to report that I STILL have not had problems with battery life. I get two full days of 8-10 hour use from a set of batteries, with power left over.
Between my wife and kids, we have five different Motorola units and have zero problems communicating with them. Both my parents and my in laws have generic "no name" radio sets and the Rino also "talks" to them with zero problems. My unit has software version 2.10, and that may be a factor.
I bought a set of these for my wife and me to go Geocaching with. They do an excellent job of showing you the distance, ETA and even an approximate location on a basemap already provided in the unit (which actually saved me, when I misread a set of directions). However the best part of this unit is the ability to send and receive the location of your friends and family. It works perfectly and behind the scenes, whenever you transmit or push the call button. I love this device and it's already become a "must have" piece of equipment for any trip.
UPDATE: OK, I don't normally return to edit my reviews, but this product deserves it. I just pulled my Rino 120 out of the WASHING MACHINE. Yes, I might not be too bright, but the people who built this thing are. The waterproof device still works perfectly and there is no external damage to the unit either!
