Valve orientation

I'm going to be diving with it solo in the Lake District. 15l single tank to a max of about 20m. I originally looked at a smaller cylinder but was advised by a couple of experienced divers that there wasn't much difference between a 40 and the next size down so I might as well get used to a 40 since it can be used for other things.

In addition to this set up i'm going to look at a steel 3L back mounted pony which I will only use in shallow water for taking photo's of fish. Absolute max depth 10m. Back mounted purely to keep it out of the way of the camera.

Thanks for the advice guys, much appreciated.

Once you learn to sling the 40 correctly I doubt you'll want that 3L.

Hi Mike,

I don't know how deep you go but in my opinion a 40 Al for a pony is bit big if you carry already a 80 on your back. Unless you do CCR or something like that. If you have question about your solo certs let me know i ve done mine with sdi last summer.

Be safe

Wtf? The size difference between a 30 and a 40 is minimal.
Always do your research before believing random people on the internet.

I did ask if we was on backmount or not for primary air. After that if it s recreational diving a 40 Cf it s half a regular tank. IMO overkill for intended use for poney bottle, redundant air source.

Taking more gas in a cylinder thats so minimally different in size that you will never know the difference is overkill?
There's no such thing as too much gas. Nobody's talking about slinging a 30 vs slinging a steel 72. You get a little more gas in the 40 with no major difference in weight or how it rides on your body.
It's a no-brainer and why I would wager to bet that 75+% of solo divers are usnig 40s.

You've never been to Taco Bell!!!

But truly, I've never been disappointed that I had too much gas. Ever. I've met quite a few people who didn't bring enough and were glad that I did. Yes, I've handed off two tanks at this point. I was quite amazed when one of those recipients simply wanted to continue their dive. WTF???

There's a reason my old ass hasn't eaten fast food in 15+ years. Meanwhile in college I ate McDonald's or Taco Bell 2-3 times a day.
