I'm now looking at the McMurdo Fast Find personal locator beacon:
http://www.gps.co.uk/htmfiles/surveqip/fastfind.htm
The question is how necessary is it to buy the Fast Find Plus which incorporates a GPS receiver and transmits position accurate to 30m or is the Fast Find adequate at a mere 3NM? The Fast Find costs about £350 and the Plus costs about £700.
I guess the Fast Find Plus is much better, but it costs an extra £350. Expensive business this, isn't it?
