Input:
The Garmin Rino 110 occupies an awkward middle ground between being an
interesting toy and a serious tool for the outdoors.  On the one hand
the idea of melding together GPS and radio communications via FRS/GMRS
is dynamite.  Unfortunately the devil is in the details when it comes
down to actually using them.  As others have noted the 110 can be
quite finicky about battery life, and even a slight jostle can cause
the units to shut down.  There's also the issue of range.  I have
found that best way to use the 110 is for car-to-car communication, or
within the controlled distances inside of a campground.  I would be
very careful before trusting the 110 in a real "hardcore" outdoor
situation.
Within those limits the 110 is a nifty little device.  I am quite keen
to see that the folks at Garmin come up with next.  I for one would be
willing to pay more for a unit that is more "ruggedized" or requires a
license but gives you more radio output power in return (and removes
the FCC restriction about sending GPS data at GMRS power levels).
Also a more clever approach with regard to batteries/power management
would be a huge plus.
