You didn't get a lot of feedback so I'll chime in. I have a couple and they are great for your use case which is the same as mine when I'm hunting with a group in Idaho. Having the GPS coordinates is really nice and makes it a lot easier to find each other. I've got a bunch of Retevis UHF radios and while they work ok when you are within a mile or so in timber, UHF doesn't go very far in timber and it's hard to direct someone to a location. The GMRS frequencies give you a lot more distance, they are sturdy, waterproof, weather updates, and the battery charges seem to last quite a while.
Downsides are the cost and they're kinda heavy. The screen and mapping are just ok - I prefer to use GAIA on my phone for the actual mapping and photos. Like Fullfan, I also use an earbud with a mic. If only the Rinos also had the Inreach Mini features...
