Find it interesting that most of those seen carrying a SPOT or similar type device, in my Sierra, are those hiking in groups, and travelling on the most, well-traveled trails...JMT, Whitney, North Lake/Humphrey basin, Half Dome, etc.
"California, which fields the most search-and-rescue calls of any state, started tracking missions initiated by PLBs and SENDs. From 2013 to 2014, they increased from 53 to 87, and 36 of those 2014 calls were either accidental or non-emergency...Stats from the Air Force Rescue Coordination Center, the first recipient of distress calls from PLBs, 80 percent of its calls are false alarms.
Australia had the world's highest per capita use of rescue beacons as of 2012. That year, only 109 out of 1,700 activations were genuine emergencies.
My greatest concern - "The risk to search-and-rescuers is always a serious consideration. Thirty-two rescuers have died on rescue missions in the National Park Service's history."
