Thats an interesting point actually, maybe something to attract attention to yourself that doesn't rely on networks. Perhaps a GPS beacon? The use a totally different system I understand.
One of the Breitling Watches has an Epirb built in. Broadcasts a distress and location signal for 24 hours. An Epirb as a stand alone item is maybe £300.
A Sat phone is about £50 a week to rent for a trip. Should get around lack of coverage.
Again it's about proportionate response to risk.
@21stCentuaryPict. In terms of the bowstring I wasn't questioning how long the string was I was trying to envisage where you were going and what kind of duration you imagined a bowstring being a desirable item?
