I carry a PLB at all times in my vehicle [1]. In the US this device will summon rescue via satellite. I recommend it for anyone who spends time in remote areas. If you value your life at $1MM and there's a 1 in 3500 chance [2] that summoning emergency services in a remote area will save your life then this is a helpful risk-mitigating tool [3].

2. $280 / $1MM ~ 1/3500.
3. A useful metric might be 911 calls, of which there are 240 million in 2008[4], for the US population of 305 million. If you assume 5% of the calls are life-or-death, that your daily odds of needing to call in remote areas are the same as the country mean, that you spend 5 days a year in remote areas, and a 5-year useful life for the device, then there is a 0.2% chance the device will save your life.
