I just got a new octopus. Is it natural that it doesnt breath as easily as my main regulator when not in water?

Like Harold says, it can depend on the brand and model.

I happened to be discussing Octo's with the Training director at the shop that I patronize and he made a good point. It is in your best interest safety wise to ensure that the secondary air source (your octo) is up to the same performance standards as your main regulator. And even better is to have the same second stage as an octo that you have as your primary.

If you think about it, this makes sense. If your dive profile includes considerations beyond recreational limits (deeper than 60 feet on standard air), you want to make sure that your octo can handle the same demands as the primary.

Therefore, I'm making the case that when making your gear purchases, DON'T SKIMP ON YOUR OCTO. Consider getting the same second stage as your primary.

How well does it breath in the water? (which is more important than on the surface).

I noticed the same thing with the diving club's gear I have been using - when testing the octopus, I noticed that it felt a bit rough, and made a buzzing noise when breathed. It's the same make as the primary but not as high quality I think.

ok guys / girls

important point - most regs will buzz / vibrate / sound & feel funny at the surface - this isn't the environment in which they are designed to operate - the best regs in the world (poseidon & apeks IMHO) sound like / operate like cr*p at the surface, but the minute you are under - WOW !!!

occys (built by the same companies) are built to the same standards as primary regs - they may have fewer knobs and buttons, but the internals (the important bits) are just as good (or bad) as the primary's

as previously stated - DO NOT SKIMP ON OCCY'S (as the thread starter hasn't)

safe diving

In general most octopuses do not breath as well as a primary on purpose. As was stated earlier you will notice a difference in performance underwater, however the octo is set to breath slightly harder for a reason. 99% of your time your octo hangs at your side and doesnt do much. If it is set to breath as easy as possible there is a greater likelyhood of it beginning to freeflow as you dive. Rather than waste air, the octo is set to be slightly harder breathing than your primary to keep this from happening. It wont breath as well as your primary but then again you wont be tooling around the reef breathing on it, if you need to use it, it's time to abort your dive.

hhmmmm...i'm a bit concerned - are you really saying that the only time you use your occy is when there's an incident ? - so it could have been up to 11 months since last used (assuming you service it annually) ? - excluding that obligatory 2 breaths immediately before plunging into the depths - I have to confess that this non-use would flash through my mind as I reached for the little yellow friend in time of need

if it interests anyone, I regularly (every other dive) switch to my occy mid-dive and finish the dive on it - then I know it's going to be there for me (or another) when I need it - am I alone ? or just super-careful ?

Actually, this sounds like a pretty good idea to swtich to the octo during a controlled period like a safety stop.

I'm going to my dive club meeting where I will see several of the local dive guru's. I think I might ask them about your idea.
