@LI-er You use a nautilus? Can I get your thoughts on the device? I've been considering getting a PLB, and the nautilus seems like the best option in several respects (already dive rated, no subscription, designed for diving, not bulky) but the reviews I've looked at expressed concern about range, and from what I've read, it doesn't alert emergency services, just broadcasts a distress signal over the radio. That being said, I don't love any of the other options I've seen, so I'd love to get your take on the nautilus.
