Interesting albeit somewhat dated article on Personal Locator Beacons from the Rescuer’s Perspective, that sheds some light on the issue of PLB vs two-way communicators. Some interesting points:"The fundamental problem is that neither coordinate came with an estimate of the certainty, or possible error." -- The PLB was off by up to 1 km and the rescuers did not know which side of a swollen creek the subjects were on."In the face of uncertainty about the position of the subjects, the team fell back on good SAR training – cover all the bases" -- The implication is that had the rescuers known the subjects' location with more certainty, the rescue would have been more targeted and efficient, not to mention economical.
