Single vs doubles.

[Linedog]

Where I dive it's common to have a bit of deco obligation. I dive a single 130, I get tired of swapping tanks and hanging around on a SI. Ya think I might enjoy a set of HP100's more than a single 130?

I'm curious, please clarify what "a bit" of deco obligation is to you. Your profile suggests that you are only PADI AOW certified with < 100 dives. Is this correct?

I would hope that anyone incurring deco obligations, especially in a solo diving context, would already have a background in gear selection and dive planning to ensure they have adequate gas supply and redundancy to get back to the exit point safely.

You solo deco dive with a single?

 

[Teller]

If your already conducting deco dives then I assume your a mature enough diver to choose your own equipment.

If you find sitting around on the surface doing a SI dull you might want to think about whether sitting around at a deco stop is more interesting... especially by yourself.... I agree with the others, you seem to be racing ahead of what is prudent.

Solo + no redundant air source = bad things.

Solo + no redundant air source = bad things.

Solo + Deco + no redundant air source = Hubris

SCUBA + Hubris + time = accident (can be fatal)

Personally, I use the surface as the redundant air source on the majority of my dives since a lot of my dive sites are fairly shallow and without deco or entanglements, have been since "63.

I think you should be looking into a ccr rebreather, why lug around heavy steel tanks?

 

[Linedog]

Sorry, no I don't dive solo right now. When my cousin and I dive we tend to go deep and my computer (ProPlus) usually wants us to hang for a few minutes. He's my redundancy, I was basically thinking out loud, doubles vs a single and a slung tank or pony. Just doing some research.

Your sac rate + time + depth = correct tank choice. If you can do your current dives useing a lp 72, then you could do 2 dives on 1 set of hp 100's and have reserve gas at the end of dive # 2. If not bigger doubles or no doubles is your best choice. Also doubles without valve training or the discipline to dive indies with gas switches = another not so attractive scenario.
