Change in buoyancy from 12l to 15l cylinder

And the ups?
Less lead I guess?

Less lead, and since they're a little bit smaller they're a little bit easier to stow when I load up my boat with gear.

Did you try them in doubles?

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



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.

I’m talking about steel 15l. It’s fine to dive with but imo it’s not optimal as far as stability goes.

This is total camel dung.

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.

As I mentioned in a previous post, the conversions I found for L to Cubic ft. was off. I use what I think would be a 17L for you, at least according to the table I posted. The biggest difference with the 17L is that it is longer than the 15L. This may account for why I have no problem with stability or comfort. The 17L is a bit larger around and a bit longer then an aluminum tank but then I am proportionally a bit larger around and a bit longer than the average diver.

No, I prefer singles. A 10x300 (or a 12x232, or a 15x200) is enough gas for me for one dive. Swapping a single tank is easier than faffing with fills between dives, and a single 10 is noticeably lighter than twin 10s.

I’m talking about steel 15l.

200, 232 or 300 bar? As I tried to allude to in a previous post, there's quite a bit of a difference between those. "15L" alone doesn't make much sense, you have to include the pressure rating. Mass (weight), balance and buoyancy is rather different between those.

Apart from that, I agree with others in this thread that your blanket statements would be better suited as manure than as information.

That sounds... excessive. What's the capacity and pressure rating (imperial units are fine, I can do the math)? Over here, if you need more gas than can comfortably be carried in a 15x232 or a 12x300 you'd rather carry a small rec twinset like a D8.5x232 or a D7x300.

Again, for the average diver maybe. I’m a large guy. I have an XXL wetsuit, XXL bcd, why not an XXL tank? Plus my wife and I start and finish with the same tank pressure. Then there is cost and simplicity as mentioned.

Out of curiosity how tall and how much do you weight ?

I already posted 1.96m, 118kg. That coupled with being a newish diver (under 100 dive) I use a lot of air. I probably could make do with a 15L but I have heard they are uncomfortable and unstable.
