User Review: Garmin Rino 530
I think this product is awesome. All aspects of it work great. GPS can be increased in heavy cover areas by enabling WAAS. Two way radio works good to about 10 miles, about 5 or 6 if many obstacles.
Others say this isn't a good product, but I think that's because they don't understand a two way radio's operation. Two way radios work on line of sight. That's just the way it is. If you're in a ravine and the other person is on the otherside of a big hill/mountain whatever then you won't be talking. Only low frequency long range radios can conquer obstacles with ease. A high frequency two way radio must have at lease limited line of sight to work.
If you understand the limitations of a two way radio then this product is awesome. I love being able to have a two way radio/gps/ weather radio all in one. The weather radio you can darn near use in a cave, as it is transmitted at a very low frequency.
