If you visit the mountains to hike, climb, ski, or backpack at least a few times a year, Rocky Talkies are probably worth the cost. They help your group stay in touch in places where cell phones fail at a fraction of the cost of a satellite messenger. They are much more durable and have a better range than cheaper walkie-talkie options, and I highly recommend them (especially for hiking and climbing 14ers). If you rarely go hiking or visit the mountains, you probably do not need a pair unless you really want them.
