| OXY2 / Tecme I really like to know what my PPO2 is. I looked for a while at the Oxygauge, both reports and sales on ebay. In the end bought a Tecme single display. This was about half the price of the Oxygauge. Not quite as neat though.
I also have an Oxy2 and use this with an Aladin O2 X computer. This is wireless, uses two O2 cells and continually computes your deco calcs as the PPO2 varies. Other than the requirement to put a spacer (Tecme again) on the exp. hose this is a excellent, but expensive, solution but I think worth the difference compared to the Oxygauge. Remember ebay will frequently get you what you want if you are willing to wait for it to come up.
