It may be useful technology in the case of a ditching where folks are floating but injured or hypothermic and therefore unable to manually activate a PLB.
In the N Sea this is handled by an ADELT - although survivors on the surface drift away from the fuselage, hopefully the ADELT drifts at a not too dissimilar rate. That said they don't have a great track record of actually activating when needed! I've no idea whether the Irish SAR aircraft have them, but it would seem sensible.
