Extending dive time

[DivesWithTurtles]

the body only metabolizes about 6%-8% of the inhaled O2 per breath.

Just in case anyone noticed, I should have said that the body only metabolizes about 25%-35% of the O2 inhaled.

The increase amount of O2 helps the bodie absorb O2 in that you do nto get as tired while breathing compressed air so it would seem that the larger percentage of O2 should help in other ares of a persons metabolism.

No, your body still only metabolizes the same amount of O2. The reduced N2 load *may* make you less tired due to less insult to your system while off-gassing. And that is a pretty common conjecture but not a proven fact.

Not to go without mentioning everyone else's great points also. that said let me breakdown my last dive. fresh water spring in Fl I had on the full 6.5mil farner john and booties 1 AL80 And I guessed at the weight i needed was 18lbs of lead and Skye let me use 2 soft weights of 2lbs each that i stuck in my BC pockets I'm 6" 2" 210lbs. my BC was a new dacor talan At vest. I was all over the place! as I went down to 40+ ft I started sinking like a rock. once i got down to the bottom at 54ft i got neutral no prob. then as i made my accent Here we go all over the place. just cruising at a depth of 35ft was a chore. I'm sure practise and time will cure a lot of this. But the weight thing is a very good point i never considered. i thought i could use as much lead as I wanted and make-up for it with my BC :bonk: Anybody what would be your recomended weight for this dive ?

The day I stop learning I'm a deadman anyway! Confusous Said :japanese:

idont hink there is much you can do. if you can get nuet any where you have to be very close. the problem i see is that there is too much dynamic boyancy with the suit. if you had a 3 mil you would have much less problem. not a suggestion to change suits only that the 40 foot suit squeeze on 6 mil is a lot of effect. think what it would be like with a 10 mil suit or a 3/8" as it may be. given the dymamics of the suit you would have to stay at one depth or fight the light heavy light heavy syndrome. that takes air. static weight and boyancy is much easier to work with. how are you at the end of the dive. if you are neut at the safety stop you must be realy heavy at 40+ with the 6.5 and full tank.
