Change in buoyancy from 12l to 15l cylinder

[EireDiver606]

I disagree. But then I'm 1.96m, 118kg. A 15L fits me as well as a 11L Al fits the average diver.

Hahaha I can easily manage a 15l single but they’re not balanced underwater. They are unstable and uncomfortable no matter how big or tall you are. It’s not about size it’s about height of the tank for a taller diver. Just get doubles if you don’t mind a 15l and be amazed at how much better they are.

I tend to agree. Although I disagree that it is an issue that good control in the water wouldn't be able to handle with hardly a thought.

The other option is do like me and go sidemount, even lower center of gravity and all the more stable. I think the issue is, side or back mount doubles, that there is more involved than just buying another tank and strapping it on your back. Not all options suit everyone equally.

My first tanks were 15L. One 200 bar, one 300 bar. The 200 bar tank was about the same height as my current 10x300s, but a bit fatter. No issues except I needed more weight on my belt compared with my current 10x300s. The 15x300 was a b*tch to haul and carry. I can't speak for 15x232s, though, because I've never tried that.

I never said that so how can you disagree? I agree that with good control in the water would help you handle it.

I’m just saying it’s easier to tilt slightly with it than other more regular setups.

Must be my misunderstanding. I took it that you calling them unstable and uncomfortable meant that they were not an 'acceptable' (for lack of a better word) tank. Seems like we are not far off the same opinion anyway.

In your opinion. My opinion although it's based on a limited experience of 700+ dives using single 15's is the polar opposite

Just get doubles if you don’t mind a 15l and be amazed at how much better they are.

Such a sweeping statement - it might be the best for you with the type of diving you do but it doesn't work for everyone.

Doubles or singles?

Singles.

They hold pretty exactly the same amount of gas as 12x232s and weigh roughly the same on land, but are somewhat more negatively buoyant due to the smaller volume. Only downside I see is that due to compressibility, I have to cool them after filling and then top them up to avoid getting a short fill.

Only downside

And the ups?
Less lead I guess?
