In reply to Rob Exile Ward:
OK. I'll bite. (If I REALLY have to explain it).
Despite having assessed all the risks, and taking extreme care at all times, the hill walker misses his footing and breaks his leg, in a remote location. If he/she has a mobile phone, presumably you would not argue with them using it to summon assistance? (Just as someone might phone for an ambulance if they stepped off a kerb on the high street and broke their leg - This actually happened to a friend of mine, who, having walked a long way on a high alpine route, stepped off a kerb while walking into Val D'Isere and broke their leg). Supposing there is no phone signal? What do they do then? That's where a PLB might just come in useful. (It does, after all, provide a GPS fix on their position). Otherwise, the hill walker has to rely on being reported overdue (which might be hours, or even days later). Mountain rescue then has to search the whole route of the hill walker's itinerary in order to locate them, wasting their time and potentially reducing the casualty's chances of survival/recovery outcome.
Or perhaps it is more reasonable to expect the casualty to splint their broken leg themselves and walk out?
As an aside, I did slip several years ago whilst walking in the hills and dislocated my shoulder. (Those of you who have done this will know that it's "a wee bit sore"). I walked out myself and did NOT call for assistance getting off the hill (although I did request an ambulance to meet me when I got to the road). In fact I had difficulty persuading the ambulance call handler, that I did NOT require a helicopter rescue. This does NOT make me a "hero", but it does, I would hope, make me self-reliant.
A broken leg on the high street, is not a calamity; a broken leg in a remote location, where there is no means of telling anyone, is potentially life threatening.
So you're presumably now going to tell me that I should never go alone to the hills? And yet many people do this, for whatever personal reasons. Do you disapprove of them all?
As I have REPEATEDLY said, a PLB is "INSURANCE", a last option, only to be used when ALL ELSE fails, in the UNLIKELY event that a "dreadful calamity" does occur. I don't know why this concept seems to be so hard to grasp. Is your house insured? And yet I assume you don't leave a candle burning in a saucer full of petrol next to your sitting-room curtains when you go out? Or perhaps a couple of batteries in a bagful of steel wool, beside your meths store underneath the stairs?
I can't BELIEVE I replied to you!
IF you're having a laugh, well done, you got me!! (So difficult to know on this medium).
And if you are, I hope my response gives you a chuckle!!
Cheers.
