Wow, good story. OK, automatic vest with lots of refills. I fish alone always, and 1/3 of the year, I've got a ton of cold weather gear on.

Its an awful truth, but, if you happen to get thrown out of your boat and knocked unconscious, you can't manually inflate your vest.

The two things I fear are:

Getting thrown out of my boat and being knocked unconscious
and
Falling in while fishing in heavy gear

The SOS with the automatic inflate appears to be the solution, and having refills to deal with mis fires that happen.
