Getting off the grid and away from it all is good in theory, but perhaps a little communication isn’t such a bad idea. This is where the Garmin RINO 655t GPS/2-way radio comes in quite well. It can put TOPO maps, FRS/GMRS radio, altimeter, compass and weather radio right in the palm of your hand.
The NOAA weather can alert you to incoming storms, while the waterproof design is up to IPX7 standards so it can endure a storm or two. There is even a built-in 5-megapixel autofocus camera with automatic geotagging functionality.
There are times to leave the iPhone and other handsets at home, but this is one radio you shouldn’t go into the wilds without.
