Default O2 Reg Recomendation for Flyers/Divers

For those out there that are also divers, I've reached the point where I need to have an O2 emergency kit handy for diving. I can't see having two separate systems for flying and diving, so I'm looking for a good recommendation on an 8-25L flow regulator that would work for both purposes. The DAN kits are nice, but have a premium $$ so I figured I can put a kit together for a little less.

Default o2

What exactly are you using O2 for while diving? A rebreather?

With his reference to the DAN kits, in diving this is used for an emergency O2 supply as first aid on the surface if needed, not actually used during the dive.

Just looked up DAN kits. Cheapest would be to use a standard medical O2 cylinder such as an E with a medical regulator. You can get these relatively inexpensive on ebay. You would also need a collection of masks including the standard non rebreather, one with a reservoir and maybe a positive pressure device such as an ambu type bag. Again should be able to get on ebay. This type of regulator would not be approved for aviation however with dry oxygen and carful use could be made to work with a small risk.
Usual disclaimers.

If you are going to be using this for diving, you will need a separate O2 cleaned regulator dedicated to just O2 use.

Don't use it below 20'

Different O2 system. The o2 kit referred to for diving would be for emergency purposes (Decompression sickness treatment) on the surface.

Although I have considered using my 40 ft3 deco pony bottle for aviation use, having a reg in the mouth while flying may not work so well.

I'd be interested in the system the OP eventually decides on.

Ah missed that.

I've flown with a reg in the mouth before. I'm sidemounting tech/cave so I've got a 6' hose and can stash the bottle pretty much anywhere in the airplane. Its a bit of a pain though, and you go through the Oz pretty quickly.

Default Emergency O2

As assumed, this is for emergency use. I DM classes and do some dive leading and really need to have an emergency bottle handy. Masks are pretty cheap, and bottles are pretty standard, so it's the reg that's the question.

8-25L is way too big for flying, unless you are going above 18,000ft. Regulators are only about $30, so I would get one for each use. I have a Drive mini 0-8 for my plane. I wish I had gotten a pediatric 0-4 (It gives finer adjustment at the lower end of the scale). At 12,000 feet I usually set it at 0.75 to 1L for two people. - I am using Oxymizers.

For emergency use you need the larger volume because you will be using a face mask with 100% oxygen. Flying you just supplement enough oxygen to keep your pulse Ox in a safe range.

Thanks, that makes sense, I thought the airborne delivery rate would have been higher. Separate regulators may be the best option.
