Where to get air in Madison?

The places that do hyrdo's do all kinds of tanks- co2, welding, scuba, fire exstinguishers.

I never heard the rule about hydro places being responsible for visuals- as I have never seen a vip sticker on an 02 bottle filled with aviators 02 which is meant to be breathed.

VIP's are dive industry ideas- just like c-cards. There is no law that states you must have a c-card to scuba dive- that's a dive industry self-regulation giude-line to prevent people from killing themselves and giving us all a bad name. No DOT laws for those- just hydro's.

Gas fills can be metered for sale- as I have paid by the cubic foot for gasses in the past. This is especially true for argon, 02, and helium fills.

Many of the more advanced shops can do tops offs and only charge you for the gas used- which is where a helium analyzer really comes in handy so you don't have to dump out any trimix to remix on top of it. It saves so much money to just pay for the helium you add compared to dumping/pumping a whole set of doubles.
