You'll need a few essentials to keep safe in the wilderness, and one of the most important is a quality communications device. While a reliable GPS unit or low-tech but consistent compass can help you figure out where you are and a first aid kit can help patch you up in the event of an injury, if you have a major emergency you HAVE to be able to get in touch with the outside world, and your cell phone may not cut it. A walkie talkie or two-way radio is a good way to keep in constant communication with those back home who can send for help. If you know someone traveling to an out-of-the-way locale, give them one of the great compact radios below so you don't have to worry about them. And since it's smart to have a GPS along for most trips anyways, why not use a GPS Walkie Talkie so you can save on space? You already have a digital camera binocular to limit the amount of gear you're carrying, so be smart and combine as much equipment into as small and effective a package as possible with one of these awesome communication tools.
