If you’re going to take an adventure, buy a personal locator beacon (PLB) and register it to make sure there’s a way to send for help should you need it. Here are three to consider carrying with you on the next journey.
The Signal: This palm-size unit combines a 406 MHz satellite beacon with a 121.5 MHz radio signal for faster response. It has 50 GPS channels and can run continuously for 24 hours. It's waterproof to 10 meters, has a six-year battery storage life, and is the least expensive of the trio.
The Drain: It does not float unless it's in the provided buoyancy pouch, and it has the fewest available GPS channels.
