<font color='#000080'>They will be significantly heavier. Personally, if I used 300bar 12s I'd be overweight with no weight on me at all, and once all the other bits I need for a dive go on, then I'd sink like a rock.

To be honest, if you really need 300bar 12s, you might be better off with twin 15s wouldn't you?

And if you're going to be diving twin 12s, you probably want to be on nitrox, which is a real pain to blend to 300bar, and if you're oging deeper and get into trimix I don't know of anyone who uses 300bar tanks for it.

I think Wacker's got a set of 300 12s, you could ask him. He'll probably be along in a minute anyway.

Hope this helps.

Digs.

<font color='#000080'>They do exist, and you can buy them. Tell them to stop trying to sell you what they can get, and tell you the truth. Faber website makes it quite clear they're available, and I can think of at least 5 or 6 suppliers who can get them for you, or probably have them in stock.

I don't see how this is working mind, you start off by asking about 300 12s, then say 232s are the answer, then ask in your LDS about 300 10s? You really don't know what you want do you! Don't worry, I had the same thought when I started buying tanks, got a set of 300 7s, then moved onto the 232 12s, and I'm about to get a second set, probably 232 7s for pootling about.

The weight off the belt with 300s is a bit of a false economy. The steel isn't an efficient way of carrying the weight, especially on land vs in the water, possibly better to get bigger 232 tanks and put the weight on as lead. You'll need less weight out of the water overall. That said, I like having my set all on my back, but I can get that now with a V or P weight.
