&nbsp All,
I got an IANTD Enriched Air certification as part of my Overhead Environments course, and I have a few nitrox dives. Your mileage may vary, but I've never been bitten by the nitrox bug. It's always seemed like an added workload that I'd just as soon avoid. Now, if I were to dive commercially I'd do mixed gas dives as part of my routine, but as a recreational diver I'd just as soon dive conservatively, watch my hydration and take long surface intervals to manage the risk of DCI.

&nbsp People tell me that they feel more energetic after diving on enriched air. I've never noticed, myself. Also, I'm just a beachbum so I have no problem with taking an afternoon siesta if I'm feeling groggy after my morning dives.

&nbsp Now, there are times when I'm diving technically and I'd like to have a bottom mix, travel mix and deco mix available. Unfortunately, the times I've really wanted to dive nitrox I've been in remote areas where there was no oxygen availability beyond the DAN kit. Often it's hard to find oil-free air. So, I dive air and take Pyle stops, extra deco stops and longer surface intervals to buy myself some margin. It's no fun hanging on a deco tank for an hour, but doing so is a low-tech way to manage elevated nitrogen levels in the bloodstream.

&nbsp Normally, I'm diving conservative recreational profiles and don't have to resort to gas analysis or using tables and formulae to manage my risk of taking a chamber ride. I don't fault anyone for using enriched air to enhance their safety or their diving experience, but I don't want the extra workload or the risk of making a mistake and going into oxygen toxicity syndrome. I'd rather rely on being extra concervative.
