Working out details for a trip to NM. Mountain High seems to have a solid reputation but a fairly steep price compared to Aerox.

No joy on W&W or anywhere else. The MH system has some genuinely tantalizing figures of merit, just priced 300 bucks on the high side.

Any opinions? Better yet, anybody with a system to sell that might work?

Mountain High is the best.

Richard,
Mark, I don't understand stand your comment about not having to wear a cannula - you'd rather wear a mask? And EDS doesn't allow cannulas?

I believe he refers to the oxy-saver "moustache" style cannula; I flew with those with an aerox system, and the EDS type is much more comfortable (and possibly stylish). I bought 2 MH older D1a's on ebay for $250, so keep an eye out there (sold one to pay for both). They don't refurbish them anymore, but they work if you watch them with a cheap pulse oximeter (~$20 at walmart). MH has a closeout/refurb section, for newer and occasionally a D1a system. I use mine for a mountain soaring camp annually, and MH products are worth the money (I flew in CO for 5 years with constant flow, and wish I'd upgraded to MH then (saves a lot of oxygen, aural warnings, works great). The second-hand market for MH pulse demand systems is pretty strong when you want to sell.

Dan is correct- I was referring to the Oximizer "mustache" cannula that looks like a large flesh colored growth on your upper lip. They help conserve O2 with a properly calibrated manual flow valve and a constant flow system, but the more efficient EDS uses a normal cannula. NOTE: Do NOT use the Oximizer cannula with the EDS! It will not reliably trigger the pressure transducers in the EDS and you will not receive sufficient O2.

The money you will save on oxygen refills using the EDS will pay for the unit.
Ditto on leaving the unit on automatic and use it from take-off to landing.
It was very impressive to experience how much more alert I felt at the end of a long day of flying when I used the EDS as compared to the old manual systems.
Consider the EDS to be an airbag system for your brain.

Thanks everybody for the feedback. Looks like I'll be going with the MH system. I appreciate your opinions and advice.

There is a good presentation on types of O2 systems at
http://aviation.derosaweb.net/presentations/#oxygen.

About the fingertip O2 saturation monitors.
Being in a glider we need one that is sunlight readable.
The cheap OLED ones don't seem to be sunlight
readable. Anyone found one that is?
Also, anyone have good experiences with the
wris****ch type O2 monitors?

Thanks, John (OHM)
