Hi Joel
All modern beacons should have GPS, the difference is that the EPIRB and
non AIS personal beacons transmit your position to satellites, at 406
MHz. This signal is then relayed to the closest coastguard station for
coordination.
The AIS beacon will summon help, if you are in range of a receiver.
Essentially any AIS receiver - coastguard, commercial, recreational user
will receive it. In a busy area this would likely get you help fairly
reliably. The signal should pop up a special Man OverBoard alert on the
receiving AIS. PANBO.com has had a few blog postings on this topic.
My view - if sailing a crewed and equipped boat I'd lean toward a
personal AIS to enhance the ability of the boat to find me in the dark.
Someone on the boat could call for additional help if required. Fairly
significant $$ investment though, and an EPIRB for the boat is still a
good idea.
If I am singlehanding outside busy areas I go with the 406 personal
beacon attached to my PFD.

I've been looking at PLBs. Some seem to be GPS based like an EPIRB.
Others are AIS based and apparently display on an AIS receiver but do
not summon help. If I'm alone I want help. If I have company I want
to be found. Which would you buy for coastal/bay cruising assuming
you have AIS onboard?
