Mine are close to twelve month old and was told one can sevice their own jackets according to Makers Specs/Recomendations and keep a log of such.
Rang marine safety and was advised to go by what the Manufacturerer of the Vests states on their jackets.
I have the Crewsaver Auto Inflatables and under the back of the neck there exists three pull out labels with their advice and owners manual as well as where Name , Date & Sig of Jacket Service.
No Rocket Science there .
Just was wandering if this is the norm for most inflatables or not??
