What Deco Algorithm do you use? (Poll)

[rddvet]

..well, that's just a bit silly when you can watch what happens to your loop using an ECCR. O

What's that mean to the people that know nothing of rb's

constant PPO2 = always best mix..
no need to get to a certain depth for a specific gas switch..

I'm currently using 50/70 for deco dives. I'm experimenting with 70/70 & 65/65 on no-deco dives, but I haven't started using this on deco dives yet. I've also been known to occasionally use DCIEM tables - I haven't done this in some time, but I'm still not at the point of saying that I'd never use them. One other strange thing with me is that I only started using a computer for deco dives quite recently - probably about 5 years ago - before then it was tables,

Thanks,
Robert

This does not seem to make any sense to me..
Please explain?
It sound what you are saying an doing is that you cap a NDL dive at 70% respectively 65% of the Buehlmann model..
Not sure what the experimenting angle would be as when you use such settings and stay out of deco it says that you were diving vers well within NDL limits.. no more no less..
Or am I missing something?

Jax, the piece I was not getting was the experimenting fo GF values around NO DECO dives..
That is the angle that does not seem to make sense to me..
Your examples are all well within Deco dives..

[MichelleC]

Jax, the piece I was not getting was the experimenting fo GF values around NO DECO dives..

The GF will in part determine whether or not it IS a dive requiring deco.

[midway]

What PfcAJ says reflects my understanding and approach as well. Moved from VPM-B to Buehlmann with GF (default 30/80) after reading the NEDU study. Purely subjective/anecdotal but tend to feel less tired when driving 3-4 hours back home from deeper dives in Lake Michigan after the switch.

Well that part is obviously understood..

It sounds what you are saying an doing is that you cap a NDL dive at 70% respectively 65% of the Buehlmann model..

But that would be it..
So essentially NDL dives will be conducted extremely conservative..
not much experimenting..
or is the experimenting angle a comparison against other Diving comps and other models. e.g. in comparing how much remaining NDL the other models/comupters still give..
because a 65/65 remaining out of Deco will have to be even more conservative than any Suunto..

Which NEDU study, please?
