A couple of guys I regularly hunt Cape York with have these units and I was less than impressed with what they could do. There were many times where tree cover cut the signal from them so badly that my mate and I could talk to the rino guys, but they could not talk to us (my mate and I use Uniden units). We were waiting at one pick up point for ages calling them on the radios and getting no reply, we got impatient and took a drive down the track and found them walking out about 2km away. They told us they could hear us fine but were wondering why we couldn't seem to hear them. They liked the polling function on their units. If they got separated (happens a lot when you bowhunt creek lines ) the units would show where the other guy was.
We have enough trouble with our unidens up in the hills, I can't imagine I would ever buy a rino.
Get a decent garmin though, they have great features that are very handy for hunters.
