02 in peacock

[Signal 20]

who brings oxygen into peacock or orange grove while doing a normal backgas dive? I'm not talking about if your doing Hensleys Castle or lower orange grove, or a long stage dive. I'm simply talking about doing a nice leasurely backgas dive. I have never done a backgas dive in peacock and ended with more then like 7 minutes of deco. But i tend to see people bringing in O2 when making short dives. I'm just interested in who feels it nessesary to do this?

Generally you don't need it, but some people bring them 'just in case' so it's available if someone is having trouble upon exit -- rather than having to run for the parking lot. Takes away a piece of the 'paranoia pie'.

Don't forget 'The Well' so you might be seeing bottles there for those dives.

I occasionally take one if I'm working on a new rig configuration. It's a good time to work with placement and trim while taking a spin around the cavern.

Used to be before having nitrox by the cubic foot for sale,everybody used air,and deco was a regular thing,so oxygen was added to the dive plan. I can do 2 hour dives on 32%,and rarely see deco,and if I do it is only a couple minutes. I weigh out the need for oxygen based on the profile versus wear and tear on the cave due to a metal cylinder in contact with limestone. I can't recall in recent memory for non-Hendley's dives using oxygen.

I'm sure you are going to get a lot of hot opinions on this one.

Anyway, here are mine.

I have several reasons for bringing deco gas on a dive that wasn’t planned for it. One is that sometimes things don’t go to plan and if I’m stuck with a unplanned deco I'm glad the extra gas is there. Two would be that sometimes I just feel a little better after a dive if I get a toot of higher O2 at the end of the dive. Placebo or not, I feel better and that’s all that counts. And third is that sometimes me or my team will carry and place the bottles just for procedural practice since we are relatively new at this.

Yeah, by the time you've deployed the bottle -- deco is over.......

Sounds reasonable to me.........

Instructors are required to have O2 available on all training dives that *might* call for deco.

I did not know this. Are they required to have it in the water or just at the dive site ?

Then there is the time I dove with Kelly & Jim doing a fauna count on air...I wish I had 02 that dive, something like 23 minutes deco on air

A. Emergency oxygen supply is required to be on-site when training dives are expected to exceed 80% of the No Decompression Limits.

Safe diving,
