air supply question

[Marion]

Hi all, I have a question regarding the use of divers bottles as a supply.
Does anyone use them and what sort of time do you have before refills are required?

Any pictures of your set up or advice would be grateful.

I use it.
I have a male air hose coupler that screws into my reg, then that pops into the dive hose. Real simple set up. Tho I wouldn't mind popping a second filter in.

@mrthe for your link... that is exactly what I was looking for :) ... I tried it this summer and it worked well!
