Periodic Re-Packing
Just to tag onto what Harvey (Reply #5) said, an "Automatic" vest is not necessarily "automatic". To the best of my knowledge, both Sospenders and Mustang inflatable vests require periodic user/customer maintenance such as what he mentioned, but also repacking, just like inflatable life rafts. If the inflatable portion of the vest is left in the same set it can develop air leaks along the creases or wear points. An automatic vest is only automatic to the extent it is maintained in accordance with the manufacturers instructions.Although probably not stated in the manufacturers instructions, I would think this would also include checking regularly for the manufacturers recall notices. For example, see Coast Guard recall link: http://64.233.183.104/search?q=cache:f4EtCsUSJBAJ:www.uscg.mil/hq/g-m/mse4/SOSPENDERS-recall.doc+sos+sospenders&hl=en&ct=clnk&cd=6Life is not a no-brainer, and neither are 'automatic' vests.
