| Imported post To answer your questions:
1. Try balloon helium - its much cheaper and basically the same stuff. Its even premixed 80/20 so you can use it all the way down.
2. Basically answered above - ppO2 of 1.4 so looks fine to me.
3. Deco? Just come up slowly and you'll be fine.
4. Best way to get a porthole off? Buy it some flowers then get it pissed. You have it off in no time. No brass left on Helena Fablious anyway - me and Dave had it all last weekend on out Fisher Price rebreathers.
Troll away to your hearts content - you just making us fish prodders laugh even more. |
