If an AI failure gets you into the life threatening situation, something is wrong with your dive plan to begin with.
I'm not sure what the best approach is to achieve this, I imagine there would need to be a built in service that could connect and send a message to a phone, or a boat's GPS. It could leave the actual search and rescue response to the "InReach" Tech, I was thinking for the MK2 a more local, less of an emergency SOS.
Surfacing away from the boat in open ocean is one of the most dangerous scenarios of diving, this could work to mitigate some of that danger.
Yeah, I get the importance of the capability, it's the technical implementation that is the problem.
The Mk2 would need some way of sending a signal. The only transmitter the Mk1 has is Bluetooth and basically the distance is severely limited and would be line of sight so of little value.
The options for sending a signal would have to be cellular or radio. Cellular would only work if there were cell towers in proximity (and would also need a SIM card). Radio would add a lot of bulk and you'd need an antenna which would add bulk. Have you seen how large the Nautilus Lifeline is? https://www.nautiluslifeline.com/lifeline-radio/

mk2 got emvco certification in June
Wow, a dumb decision would be so shocking for Garmin......
They should have used the PPS Transmitter, it is really solid and reliable. But I guess Garmin needs to learn the same lesson that Suunto learned when they went off and did their own transmitter.
