Having had a re-read of the article, establishing some technical back up, looking in my reference notes, I can draw the following conclusion...
He's a Muppet
):
Only having this article as a source material, reading between the lines the bloke seems to be one of a growing group of outdoors enthusiasts that will substitute technical gadgetry over a bit of savvy. The sort that will buy a top-range GPS system but not know which way North is. It is all too easy to believe the salesmans patter and place themselves in situations where the equipment will fail, leaving them out of their depth.
That's not to say that this equipment doesn't serve a purpose, it does. it's an aid, not a crutch. There is a growing problem particularly in mountain rescue teams, where people are paniccing when it gets foggy, wet or even just tired and using their mobiles to call Mountain rescue teams. If they just sat still and thought about their situation, they would calm down and be able to get themselves of the mountain without assistance. They might be cold wet, even have to stay on the hill overnight, but they wouldn't come to any harm.
Mobiles and locator beacons are only to be used when Human life IS in danger. Not because something could happen.
That's my 2p on the subject,
Cheers,
