yes you can dive using this stuff, and perhaps it will be uneventful for you...but is it really worth dying to save a $100 hull cleaning bill.
Yes, it's worth it to me.
I see the commercial dock divers in our neck of the woods using compressors instead of tanks. I've read on a few other sites plans for the do-it yourselfer to build your own hookah outfits using oiless compressors from home-depot.
So what's the real scoop? Are they good enough or not?
