If you hike, camp, backpack, this is from a very experienced Search and Rescue leader who I took course from:<p>-First, have a Personal Locator Beacon. If funds allow, have one with two-way messaging (there's a monthly subscription fee). Needless to say, be mindful of battery condition.<p>-Second, have a GPS with maps from your area, or the equivalent smartphone app. Learn basic map reading, a good Youtube video about it will do.<p>-Third, take 3 hours to study for a ham license. Pass the easy exam and get a reliable, easy to use HT (Amateur radio's name for walkie talkie). Learn to use the repeaters in your area.<p>You're good to go.<p>P.S. this is concerning a getting lost scenario. He also recommended taking a First-Aid course.<p>edit: My recommendation for an HT is still, after 10 years, the Yaesu FT-60r.
Pros: Very solid build, easy to learn and operate (compared to others), reliable.
Cons: Bigger and heavier than newer models, battery not as good but can be upgraded. Also, analog only, but to me this is a plus as I want simple, reliable comms and don't want to invest time in zillion other features.
