Re: Inflatable PDF maintenance
There are "pills" and there are "bobbins". The bobbin being the rarer more expensive design that uses paper mache wound over a spring, less likely to crumble in moist air than the "pill" type. Since that Amazon page shows bobbin packs "bought with" those indicators...just be sure the indicator is the right type.
My first PFD was made before indicators existing, so it doesn't need that nonsense. Second one, same type, has the indicator nonsense on it, and that doesn't stop me from physically looking at the pointy end of things to make sure it will work properly anyhow. Just another nuisance.
