i tried to fly out today and i ended up being bent

Planes carry Oxygen generators, not tanks, I think. I've wondered how much O2 one can really get from one?

They have several portable tanks for such need and crew tanks as well. Standard on commercial flights.

Hi Kell,

A couple of Questions -

Was your wife your buddy on the Vandy?

What is your certification level? Did you have to dive with an escort?

Thanks.

These questions were already answered in previous post. OP is a new diver (<24 drives), in a group lead by a DM. He claims to have stuck near by the DM and his computer was clear of violations. Several other posters have questioned the marginal SI between 2 deep dives but other than that not much anyone can pin the hit on.

I read every page, and did not recall seeing if the wife was a buddy or the certification level. Maybe I missed it, but I did learn that flying in vintage aircraft has mystical healing powers.

They paired me up with another diver who has been diving for 25 years. Him and I went over things as we planned the dive the shop allowed non advanced certified divers on the wreck if you pay for a guide. I still stuck close to the DM and my buddy followed me. My wife only dived once on the trip back in Key largo. I actually had 2 computers with me one on a console and mine on my wrist only because I wanted to try the other rig I had setup for her it had a new 2nd stage I wanted to see how it breathed at 100 feet. I just left that computer in there which she was using. Both computers are Gen Resource pro's the one in the console is older it read little less nitrogen loading then the wrist strap one I had, but it read a foot or two deeper since it was hanging on the console. One will never know if I was bent before the plane ride I think if I had been I would have known because when you get bent you know it. I followed the group of 5 and their profiles were the same as mine. If you read into others who got DCS you will find this common 1 guy out of a group gets bent on the same safe no decomp dive. Both days I was dehydrated, and the day of the flight I was stressed big time and only got about 4 hours of sleep. This was probably the biggest factor in my case. I think the dives on the vandy were the best and I felt the most comfortable I have ever felt diving so far. I have had issues in the past with rental gear regulators but all that I have solved with adjustable 2nd stages I now have. This was the first deep dive I have done with my own gear.

Just got home looked at my computer shows 1st dive 24BT 93 max depth shows and 2nd dive 25bt max depth 101. Too bad I can't download would have more detail it the 101 dive shows nitrogen into the caution by 1 star. I'm not sure why it is flashing one in the caution need to figure that out have the manual it shows a picture of that but does not explain why. The computer is a genesis Resource pro also trying to figure out the exact surface time.

Couple of questions:

1)Are you saying that you surfaced with it in the caution zone?

2)Not familiar with that computer. I'm guessing it's an Oceanic type computer? If so they are pretty aggressive . I have an Aeris computer and make it a habit to ALWAYS wait for it to get into the green before surfacing.

 

[Blastman4444]

I said it was a genesis resource pro it was 1 dot into the caution on one dive.

 

[ianr33]

There are many,many computers that are "Oceanic type" computers. I have an Aeris computer. It uses the "Oceanic type" algorithm

I'm asking was it one dot into the caution zone during the dive(but went into the green during a safety stop) or did you surface with it one dot into the caution zone. It can make a difference. My Aeris computer probably takes around 10 minutes to go from one dot into the caution zone to green (Depends on profile) 10 minutes is a pretty solid deco/safety stop.

Edit: Google tells me your computer has the same Algorithm as my Aeris/Oceanic computer. It is well known to be a liberal algorithm.

It is my firm opinion,after trimix training and many years of deco diving,that the caution zone on these computers is to be respected. I'm not saying if you surface in the yellow you will get bent by any means. But, make a habit of surfacing in the yellow,throw in a couple of rapid ascents and some dehydration then,IMHO you are pushing your luck.

If it's in the yellow at a safety stop, wait the 5 or 10 minutes until it goes green. If you don't have enough gas for that rethink your dive planning!

I think that the Pelagic group includes Aeris, Hollis and Oceanic, but I don't know who makes the Genesis or how similar it may be. The wiki article says it is a clone made by Pelagic Pressure Systems, but I dunno?

I agree that I try to extend safety stops until my Oceanics both are in the green. One in the yellow is not much tho.

Other factors like dehydration add to it of course, maybe straining after surfacing, and we don't know anything about his ascent rate. Sometimes we just don't know, but we work to avoid repeating.
