Medical O2 has moisture Aviator O2 has the moisture removed They remove the moisture to avoid it freezing at high altitude. They may remove it for medical reasons also which I am unfamiliar with. Possibly pulmonary edema? You can get pulmonary edema from breathing in a negative pressure chamber or like climbers get while climbing. Maybe the dry O2 helps mitigate the effects of having less pressure at altitude. Just my guess. SIDEBAR: Scuba divers use special cold water first stage regulators filled with silicone to avoid their AIR not oxygen from freezing while diving at cold temps... BURR!

I am a deep sea diver in the Army. We breathe oxygen in the water up to 30ft and up to 60ft in a recompression chamber. The other comment was correct and good advice about staying hydrated. We deal with two types of O2 toxicity Pulmonary and CNS. CNS is from breathing pure oxygen deeper than 60ft. Pulmonary is from breathing pure O2 for extended periods of time. Pulmonary happens after breathing O2 for hours on end. You don't breathe it for hours on end and not at depth so you shouldn't have anything to worry about in that area. That was a little sidebar FYI for ya. We breathe aviator O2 for much longer times thans those. Often 30 minutes at a time with a 5 minute break in between 30 minute periods. Try some candy or cough drops after your dives to keep your throught moist. The other comment was spot on. If your are dehydrated the dry air is going to affect you much worse than if you were hydrated. Hydrate the night before diving, day of diving, and the day after. DEEP SEA!

Chuting star suggest buying a new container and fitting it with a used main, reserve, and AAD. I like this idea. It is the best of both worlds. Any thoughts anyone? I am 6 foot 200lbs what size main and rerve would you guy suggest to put in the first rig?You know what is a standard range.

Thanks everyone. Original question has been answered plus some good advice. Piifish-I will take your advice with a spoon full of sugar because you are correct and that sounds like great advice. I have a thousand more questions but I will let them wait until I get back from Cambodia. Thanks All.

Thanks PhreeZone. What is the best place for used gear. I am just so iffy about used gear. Who does the assembly of the rig if you buy it in parts? Virgin-Burner-I have two jumps. I wasn't looking for a flow chart. You know step one, step two, and step three. Any more good advice?

That is sound advice. If it included a main and reserve I was going to get new gear. What about sizing and reliability with used rigs. Also what if I want to get a rig retro fitted with a skyhook? will all rigs take them or just UPT or just some rigs?

I want to get into skydiving and I am pricing new gear. On the UPT website they list the Vector 3 M-series at 2400 plus the AAD which is 1500. That is 4000 bones basiclly. My question is does this come with a main and reserve at that price or is that extra. I couldn't email the site because my email is jacked. Hope you guys can provide me with some info.
