Twin 7s

[JamieG]

Now I may be being thick here (please help if I am) but I can't see a benefit of twin 7s over a single 15l cylinder. About the same gas and I would think similar diving where you can buddy breath to the surface should a problem arise.

Twin 10s yes but 7s whats the idea here?

I dived twin 7's for years, they were a lovely set and nicely balanced, prior to that I started with a single 12 and then added a pony. Twin 7's were far nicer. Lots of ladies go the twin 7 route.

to provide for a redundant air source, providing you can shut down properly. Your buddy shouldnt really be your first back up.

They are closer to your back, making the whole set more balanced and a lower profile... I have a 300 bar set and are ace to keep your configuration the same as bigger twins without the weight. They are a real pleasure to dive with. Also 300's mean a little weight off your belt too.

Thanks for the replies.

Ladies - yes I can understand that.

Redundancy - ermm shuting down on that little gas I think would be a problem for most people.

Trim and profile - I've never used them so can't comment but surely they can not be as easy as a single 15?

I seriously don't get it.

I use them because I get to dive the same configuration as my bigger twins without the weight.... they are easier to dive than a single on a stab...

Fair play I get you now, they will match a bigger twinset better than a single,but I don't think I have a use for them myself, maybe a set of independent 10s would be the way forward though rather than a single 15l? I just don't do the sort of diving that warrents twin 12s.

I used to own both twin 7 232s and twin 7 300s. I preferred the 300s. They were lovely to dive. I could get two of my usual Farnes/St Abbs dives out of them and still come back from the second dive with a good reserve of gas. Bar for bar, I matched my buddies consumption on his twin 15s, so we always knew pretty much what each others' guages read.

I moved up to twin 12s last year when I realised that if there was a poo/fan interface and my buddy needed my gas, I just didn't carry enough. That and the fact that I am starting to go deeper.

I would definitely dive twin 300s again.

I also dive a single 15ltr with a Y valve... 2 take offs... I try to keep everything the same..I think the call it muscule memory.

Yes makes perfect sense mate and I can see where you are coming from.
