OMS wings vs Apeks wings and LP vs HP tanks

[cool_hardware52]

Here in the technical diving forum we always carry 3 or even 4 mixes in LP steel stage bottles to create NDL dives and avoid hanging on anchor lines with our bungied OMS wings.

That's what you need a three gas nitrox computer for. :shocked2:

Tobin, you of all people should know that trusting your life to a finicky piece of flood-able electronics that depends on a mass-market battery is wrong. The Doing It Wright approach is to calculate the Nitrox In FlighT Yardstick, or "NIFTY." I have a Nitrox-compatible abacus on the right forearm, I can track all of my mixes and recalculate my profile at will, and for cold water with heavy glooves I switch to bigger beads that are easier to operate as well as easier to see in low viz situations.
