Anyone who enjoys spending time in the wilderness or doing high-risk activities outdoors away from civilization should carry a personal locator beacon. When activated, a PLB will send an emergency signal through a global satellite system to the appropriate rescue control center. That rescue center will immediately dispatch teams to assist you in your emergency. We love the ACR 2880 ResQLink (opens in new tab) because it's been tested in incredibly treacherous situations and has saved many lives in the process. We think your life is well worth the investment.
