A Low Cost Emergency Personal Locator Beacon (PLB)

For the past two years, I have been hiking with a personal locator beacon in my pack. My ACR 2880 PLB is a 130 gram weight transmitting device that is registered with the Search and Rescue Satellite Aided Tracking System operated by NOAA. For details about this system and how it works, click here:http://www.sarsat.noaa.gov/sys-diag.html

This device differs from the Spot and DeLorme devices in several respects. First, there is no subscription cost. You just purchase the device, register it online with NOAA, and renew every two years online (I put a tickler on my calendar). The battery lasts 5 years. After that, the device has to be returned for refurbishing and recertification. The is a transmit only device designed for one time use. To activate, simply deploy the antenna and press the on button. When activated it sends out two beacons; a five watt distress beacon on 406MHz and a 500mw homing beacon on 121.5 MHz (for the S&R team). The distress beacon is picked up by LEO's as well as geostationary satellites and forwarded to local authorities with personal identification and location information. 

I am primarily a solo hiker, about 90%. I am often bushwhacking in rough terrain. If I am seriously injured or come across an emergency situation, I know that as long as I have a clear view of the sky.  I can quickly summon help, even if I am in a low spot with no cell or repeater coverage.

Fortunately, I have never had to activate the device except for occasional testing to ensure it is still functioning. However, it has provided a lot of peace of mind for me and my XYL, especially when I am activating in unfamiliar and remote areas. 

This system provides world wide coverage and is supported by a number of countries other than US. Check for suitability in your particular country.
