CO2 Life Vests Final Thoughts

If you are looking to purchase an automatic and manual inflatable life jacket, check out our comparison table above and the reviews on this page- you can also head over to the individual product pages and check out reviews from actual consumers to see what they're saying about the lifejackets they purchased. Users report purchasing automatic lifejackets for use in inflatable kayaks- they say that because these types of CO2 lifejackets are lightweight with large armholes it makes it easier for them to paddle on lakes, streams and other water bodies.

One user who purchased the Onyx Deluxe automatic inflatable lifejacket writes that he is well over 200 pounds and 6 feet tall But the life preserver easily and comfortably fit over his clothing. Some users turn on the manual option because if they are fishing on a wharf or jetty and they get splashed by water there is a chance that the life preserver will suddenly inflate. Another reason people use the manual option is if you get stranded inside of a downed airplane in the water- they wouldn't want the life preserver to inflate and potentially trap them inside of the submerged aircraft.

It's also smart to keep tabs on the CO2 cylinder- most of these units will come with a sensor that will let you know when your inflatable life preserver is not working anymore, and you can reinsert a new CO2 canister to get it back up and running. Indeed, there are a variety of different types of life preservers available on the market today- the most traditional is a standard foam life preserver that has an orange nylon color. This is universally recognized as the most standard sort of life vest.

If you are particularly active in water sports, it makes sense to investigate a CO2 automatic life preserver because they feature advanced designs to help you retain mobility. And since it doesn't inflate until you actually need it, you aren't swamped down with bulky flotation foaming. That said, most of these automatic flotation preservers are not suitable for children- you will want to investigate the different options to purchase a non-adult model that's suitable for the child in your family.
