What are the pros and cons of these different systems? which would be better for diving 20 miles off shore? Does anyone have experience with the nautilus thingy?

with a plb or epirb Range is not a issue , but rescue may take a while . size on a plb is a plus vs epirb . the ebirb has a longer broadcast time approx 24 vs 48 hours . both will need a container to dive with . make sure you get one that has a gps in it .

the life line is basically a vhf with limited range (apox 7 miles they claim ) you have to reliey on a boat hearing it on their vhf thats near by and that understand the broadcast ( and it must be a newer vhf) , A plus is it is vhf that you could call your dive boat . My fear is the short range 7 miles is a stretch IMO with a antenna at water level

Would it not make more sense putting a tall VHF antenna on the boat and rely on coast guard response? Seems to me that would be the quickest and more reliable for medivac which is something one needs to be covered when diving. Was on a boat on reefs off Bimini and it was the US coastguard we used to get a chopper to take an injured diver back to Miami for treatment. FYI the diver fully recovered from DCS due to the rapid response...... that was back in the nineties I would expect the service to be as good now.

I belive he is talking about something for the diver not the boat . In case he comes up and there is no boat to be found .

The lifeline is more geared to the diver -coming up too far away from the boat or rough seas making him hard to locate. I would leave the epirb in the boat. My main concern would be if the boat were disabled or sank. Counting on other boats getting a dsc signal does not instill much confidence in me. At 20 miles offshore, vhs reception is iffy; I have tried to raise the coast guard unsuccessfully.
