There's been lots of discussion and speculation on this site (and others) about SPOT/PLB benefits, limitations, etc. But I haven't heard much official from the guys who actually use these devices to rescue people--at least until I came across this website:
http://www.rockymountainrescue.org/about_PLBs.phpMost of it's pretty basic for those who have some experience, but it's nice to know what the guys on the OTHER end of an emergency are thinking. Definitely a good read for anyone who got a new gizmo for Christmas.
