As I mentioned a couple of days ago, I tried out twin 12's for the first time this week.

When diving with a single, my SAC averages 23 l/min. My first two twin 12 dives (at similar levels of exertion), I was at 19 l/min. Why might this be - has anyone else experienced something similar?

Cheers
Gary

PS - happy new year to all on YD

Could be your better streamlines?

Have you changed anything else? how are you working out your SAC?

Nothing else changed..... and using a bunch of similar dives as Horsea as a sensible benchmark.

Just using the standard formula, plugging in the average depth for the dive.

It's highly likely that, because you knew you had shedloads of gas with the twinset, you were more relaxed for the dive and therefore breathed less.

I'm thinking better trim as well.  When diving with my twins, I'm a little head heavy because of the manifold which puts me in a very horizontal position.  With a single, it feels like I have nothing on so I find that many times I'm actually a little head up.

What Dom said.

It happened to me when I switched to twins a couple of months ago. I always used to be, well not worried, but watching my air and now I don't have to.

Laters,
   Janos

PS - I do still monitor my air, but you know what I mean

<font color='#000080'>I dont think i have ever come up with less than about 75 bar in each 10 (including to 45m and about 15 mins deco). &nbsp;But then im a girl (breathe less) and i swear someone way back in my ancestry got a bit funny with a dolphin.
