I'm in the process of trying to consolidate, update and retire the PFDs I have managed to accumulate.
The good news is that the old stuff is really obviously old (fun/scary picture attached).
The bad news is that there are too many damned inflation mechanisms that are generally incompatible with one another.
Right now, the only thing that seems to be standard is the 1/2" threads for the 33g CO2 cartridge. Although, one of the PDFs I'm retiring (West Marine
SOSPenders, which I really like) had a 3/8" CO2 cartridge. All of the water-inflate mechanisms seem to be proprietary, along with the manner in which they attach to the PFD
Anyway, due to my location (Japan) I'm having a hard time getting PDFs shipped to me due to the HAZMAT status of the CO2 cartridges Fortunately, I have found a supply of 38g 1/2" thread cartridges. Unfortunately, I have not found anyone that will ship PFDs without the CO2 cartridge.
So, my biggest question(s) is/are: will a 38g CO2 cartridge work
for most PFDs? (Do they have a relief valve to blow off excess pressure? How much extra pressure with another 5g of CO2 cause or the average PDF? I'd rather not have a cartidge installed than have a cartridge that will rupture the PFD's air bladder. I guess I could always test; has anyone else done this?)
Next, I'm curious to see if there is a consensus about which PFD(s) are the best (with "best" having lots of different parameters, but for me, that would be something along the lines of longevity, comfort/wear, amount of time the water-inflate mechanism is good for, no false positives for PDF deployment for the water-inflate mechanism, D-ring for jack-line snap-in, zippered pockets and pouches for additional add-on safety gear
like strobe and small handheld VHF radio
I am also curious to know what other equipment
folks add on their their crew's PFDs. Right now, the minimum add-ons for me are strobe and whistle (if the PFD
doesn't already have one). I'd like to add a small, cheap DSC
handheld, but that gets kind of expensive... maybe just one or two for deck-forward crew).
Finally, I'm looking for good sources re-arm kits (suppliers who don't ship stuff that's within a year or two of needing to be replaced). I've noticed that some of the Amazon reviews
for PFDs have negative review for this reason. Case in point:
Amazon.com: Onyx A/M 24 Deluxe - Automatic/Manual Inflatable Life Jacket (PFD): Sports & Outdoors
I think, at the moment, I like the west marine
Off-Shore PFD because it *lacks* a water-inflate mechanism (on the other hand the re-arming nib seems pretty flimsy... I'd like the 1/2" threads to screw into something with some substance to it). Any thoughts or comments on that?
As always, thanks for your time and collective wisdom...
