Regulator Necklace on My Primary or Octo? #AskMark #scuba @ScubaDiverMagazine

Hey Mark, thanks for all you help, it's well appreciated. My question is for a respirator necklace, for primary or Octo? #askmark

The long hose has a second advantage.
If you're ever getting into wreck or cave diving, the long hose is long enough for your buddy to breathe off your second stage and follow behind you. This is especially important if he needs to follow you through passages the aren't big enough to go through side by side.

There’re silicon “quick release” necklaces available (Cressi) that you can use for your octo 👌🏻

Not sure how to ask. If primary is on a necklace and has an unstoppable free flow like freeze from ice diving. Which totally happens. Bubbles in your face would be an issue.

ASKMARK# I appreciate that some, but not all, divers need and/or use necklaces. What can you suggest as an alternative ‘quick release’ system to carry the ‘occy’ or secondary stage securely prior to a dive buddy or another group diver requiring air? Would a ‘Nite Ize’ S-Biner - Stainless steel Microlock suffice or simply use either a marine grade bunji strap with a fixed/non sliding clasp (as used on tonneau covers) fitted around the air hose on one end, and the other to a S/S clip on a BCD, or a large double-ended snap clip with one end able to contain, but not compress, the air hose and the other end connected to a ‘D Ring’ on a BCD or webbing strap? Your thoughts? Regards, GeeMac

I didn't post this one on an AskMark video so I don't know if it might have been missed, or maybe it was just too long, or maybe it's just a stupid question (in which case just feel free to ignore this as a duplicate and I'll happily continue on knowing I'm still an idiot, as usual :D)...

#ASKMARK Thanks, as always, for the great videos. One of the best resources out there I've found so please keep up the great work! My question has to do with breathing (something it seems to me is another bit trait of pro divers, particularly as it relates to buoyancy). Most of the agencies talk about breathing "normally" or taking deep, steady, breaths and/or exhaling fully, but it seems to me this very much skips over why we need breath control and, in particular, using breathing for buoyancy control. I've watched many dive videos and if you count how long a particular, professional, calm, neutrally buoyant and in trim diver breathes in versus breathing out even those can be vastly different (and not at all which I would think of as a normal, calm, breathing cycle). For example sitting here calmly now I may breath in for, say 4 seconds to maybe 40 or 50 percent of my lung capacity and exhale for another 4 seconds with a pause for another second before inhaling again. While not always consistent I often see where it would appear a diver might be somewhat consistently breathing in for 5 seconds and then breath out for all of maybe 2 seconds while staying perfectly still in their buoyancy and trim. Is there something I'm missing as to why that might be the case instead of a steady rhythm?

I would further note that normal breathing doesn't use our full lung capacity. At the bottom of my breathing cycle I can force exhale more air from my lungs (and sometimes do when getting under from the surface or to lower my current depth a bit) and breath a bit more shallow to change depths. Conversely at the upper end I could sip in more air than a full breath would consist of, although I don't see too many reasons for doing that and it has the potential for being a bit dangerous as you are likely ascending in that case and wouldn't want air expanding in the lungs like that. When trying to get neutral since my normal breathing cycle is at the lower end of lung capacity should I be aiming to be neutral while breathing in that range of my lungs, or should I aim for breathing more in the middle of my capacity instead to give extra "room" to exhale more to go deeper if needed? I rarely see any discussion, at least not on most videos on buoyancy or any of the training I've seen or even in the Perfect Buoyancy class I've had with SSI that really talks about the in-depth details of lung capacity and vast range we have in how we breath and how to optimize that for diving, only what I had noted above and that we can use our lungs as our primary BCD for maintaining buoyancy. Well if it's a primary tool why don't we see more details about how to really use that tool?

#ASKMARK...This has nothing to do with regulator necklaces. A question has been bouncing around my head for a while. Why don't dive computer manufacturers add a demo or simulation software to dive computers? I would think, after adjusting all of your settings and screen preferences; layout, color, data, etc. that being able to view them in dive mode would be helpful. In my case, my 13 year old is getting his OW currently and I would love to be able to show him a simulated dive screen to explain all of the data and allow him to familiarize himself with it. I think this is a great opportunity to add more safety for new divers. It can't be too difficult to add this option into the software? Have you ever heard of an argument against this or why it's not commonplace? Thanks Mark.

Dangerous snag risk around neck? Is there a proper way to tie?

[witchieblackcat]

And the reason that long hose/primary donate is frowned on by some agencies... the poor explanations.

[mustanggun]

Really? Is that even a question? Necklace is the answer.
