Yearly Gear Maintenance costs?

Also a visual inspection of the BC bladder will allow checking for bladder dry-rot, though this is uncommon unless the BC is really neglected or old. But having a BC bladder "blow out" at depth is not a good thing, especially when an inspection could check it.

How would a BC bladder "blow out" at depth? There's hardly any air in it at depth.

In any event, a punctured BC isn't life threatening...just a PITA. You can always swim back to the surface (with singles)...you don't use the BC for surfacing anyway. It'll mess up your buoyancy of course, but that's about it. And I can't imagine annual maintenance preventing a punctured or otherwise failed BC bladder. You can visually inspect it all you want, but when it fails, it fails. And you can do any inspection yourself that the kid at the LDS can do.

Inflators can be maintained by cleaning them well after every dive. Heck, replace it every so often if you want...it's easy and cheap. Rinse out the inside of your bladder too, and inspect it every so often. No way I'd pay someone to "service" my wing

Regs, of course, ya gotta do it every year. It sounds like you got a decent price.
