Sending out an SOS
If disaster hits, whether you're backcountry hiking, sailing offshore, or stranded in a blizzard, the MicroFix Personal Locator Beacon (PLB) may ensure your survival. This slim, handheld device, made by ACR Electronics, has built-in GPS technology and a unique identification number (registered only to you) that helps rescuers pinpoint your location worldwide. In an emergency, just point the PLB's antenna to the sky and push the red button. The MicroFix sends a distress signal to satellites, which relay your coordinates to your local search-and-rescue crew. It sells for $600 at REI.com, or you can get its cousin, the ACR TerraFix, for $450 (including a $50 rebate).
