From UWnewbee: some DIY use a co2 fire extinguisher tank which is not recommended since there is NO rupture disk at all..

I think my pony bottle was a fire extinguisher in a past life, it’s 2015 psi but I’ve had a few liveaboards think they are doing me a favor and topping it off by pumping it to 3000 psi without reading it or asking me! It has a nice ring at that pressure!

Had a few DM’s stop me from stepping off because they are looking at the wrong SPG and think I’m going back in with a used tank
