Source for X-Large Bottle Of 500 PSI?

[ElectricZombie]

Hi all. The last time I was down in Florida at a local shop, they were selling these large bottles of 500 PSI mask defogger. They were literally about the size of a shampoo bottle and had "Instructor" written on the label. I'm guessing it was a sort of promo. I was able to buy the last one they had, but have since run out.

I teach 3 SCUBA classes here at the University + some private classes, and we seem to go through 500 PSI really quick. I would really appreciate it if someone could tell me where I could purchase more!! If anyone has a few bottles laying around, or knows a source, I would be more than happy to purchase them.

Thanks

Contact the makers directly, they might be able to just sell you some over the phone.

Any shop that sells 500 psi can get it for you.
