The rescueME PLB1 is the smallest PLB on the market and comes with a 7-year battery replacement interval, compared to ACR's 5-years. 406MHz PLB's operate off of the COSPAS-SARSAT satellite program (which provides dedicated global search and rescue coverage and the best reliability of any Satellite network). Unlike SPOT (Global Star based) and Garmin (Iridium based) this device does not require a subscription. However, it will not transmit text messages or other forms of communication to family/friends. This beacon is for emergency use only and should only be used in a life or death situations. It will transmit on the international distress frequency, and your unique information will be transferred to mission control, then to your country's rescue coordination service, and ultimately to local SAR operations.
This model is a great fit for me because it will be taken along for a wide variety of activities. It will be used for BC skiing, Kayak touring, canyoneering and any backpacking trip where cell-service will not be reliable. I put a premium on weight, size, battery life, water resistance, long-term cost, and reliability. It is industry leading in size, weight and battery life. A PLB is an often overlooked backcountry safety device, that can ultimately save a life in a time-sensitive situation. I will feel more responsible and secure knowing that I have this lifeline in my pack. For my PFD I have a lanyard tethering the PLB to a pocket in my vest, and can use the supplied rubber strap to secure it my shoulder strap. For my backpacks I put a rubber band over the flap, so it won't accidental open, and just find an empty and accessible pocket for it.
I registered my device and tested it, following the protocol. So far so good!
