Doubles wing with a single tank?

[jonnythan]

As soon as I get my hands on a single tank, I will attach my doubles wing to it, lay it on the ground backplate-down, hold up the sides of the wing as would happen underwater, and take a picture of the resulting taco.

That picture by itself in a sticky should be completely sufficient to greatly reduce the number of these threads we see

Try this instead, take a dss 40# singles wing and put that on a pair of 72s. Go dive with it and tell me what you think.

The original post spoke of using a 55# Halcyon doubles wing on a single tank.

Furthermore, the vast majority of doubles I see are much larger than double 72s.

Therefore, your experiment will have nothing to do with the OP's question and little if anything to do with most questions of using one wing for doubles and singles.

What I am getting at is the architectual requirements of singles and doubles wings may not be as great as most of the current designs out there suggest.

Note I'm not taking a passionate position here, I have both myself, I am just offering some food for thought, thinking outside the box

My bet is someone will come up with an effective dual purpose design sooner or later. In this day and age and technology anything is possible. I doubt it would come from a present manufactorer though...

Anything is not possible. For example, can a human and a horse create viable offspring?

Nope. I don't see why anyone would want to try. Same with dual purpose wings.

Here's a couple more crazy ideas.

The use of bicycle clipless peddle technology for attaching tanks to backplates.

The use of bicycle quick releases skewers for bolting doubles together

Bob,

My point about wings is certainly based on using the DS for buoyancy. So if you don't agree with that then the rest of course is all wrong for you too.

The type of suit you are wearing has no effect on the wing's tendency to taco. A doubles wing on a single rig will wrap itself around the cylinder. Air trapped in the wing will not vent without some effort on your part to "force" the air bubble to migrate toward the top of the wing. Even if you can manage to use the rear dump, that will only take care of the air on one side of the wing.

Using the DS for buoyancy doesn't imply no air at all in the wing ... air will be trapped upon descent. It simply implies that you won't be adding more air to compensate for the effects of compression.

I first started using my BC for buoyancy, I have since switched over to using the DS. I know the tech divers in my area all use the same technique as well, including a former navy man and now current trimix instructor with 30 years experience diving.

Are these tech divers using doubles or RB? Because if they're using doubles, and using their DS for buoyancy control, I'd like to know how they manage to compensate for the buoyancy swings that occur between full and nearly-empty cylinders. I know that in my 119's it's considerable, and that in order to weight properly for the end of the dive, I am considerably overweighted at the beginning of the dive. If using a DS for buoyancy control, that's going to produce a significant air bubble in the suit.

I don't believe there is a right or wrong answer on the DS question. Maybe you disagree on that too which is ok.

No ... it's not a matter of right or wrong. It's a matter of optimal or sub-optimal. I used my DS for buoyancy for a long time, and was very good at it. But in hindsight, I'm a far better diver today for not doing it that way anymore.

I won't tell you that you're wrong doing it as you do ... I was at least as convinced as you are when I did it that way. I will tell you that, for me, deciding to put minimal air in my DS, and use the wing to compensate for buoyancy changes made a huge difference in my ability to finely control not just buoyancy but also my ability to orient myself for those delicate photography shots that may require me to be supine, inverted, or some other position.

The great part of forums such as this is that those seeking information can get varying opinions to help them make their own decisions. The bad part is where others condemn or insult or laugh at those with different opinions. That can deter those with differing opinions from posting which in effect reduces our pool of ideas. I am probably guilty of this myself though I try to avoid it.

I hope you to not interpret my disagreement as in any way condemning, insulting, or lauging at you ... I agree with you that such things are not the way to conduct reasoned conversation.

Back to my point, I don't think the name 'drysuit' and the name 'BCD' isolates their function. Regardless, I prefer using a DS at this time, it makes sense to me to minimize task loading. Maybe I will change my opinion in time as you did. I will stay open to it, I don't want to box myself into an idea due to pride.

I'd encourage you to give it a try ... give it a dozen dives before making up your mind. Diving is all about teaching your body's muscles to respond without conscious effort to the subtle changes required to make it do what you want it to do. Anytime you make a change to how you're used to doing something you should give it a few dives before deciding whether or not it makes an improvement toward the goal you're trying to achieve.

I actually have played a round with a single club, a 4 iron. Played pretty bad but for me that was par for the course!

Me too ... I wouldn't be able to play a decent round with Tiger Woods' clubs ...

Dive Rite believes that they already have one in the Rec wing. Having owned a Rec wing, I found it useable for both, but optimal for neither.

Wearing a doubles wing with a single makes some people look like dorks: :shakehead

Bob,

The type of suit you are wearing has no effect on the wing's tendency to taco.

I of course understand the type of exposure suit doesn't have an effect on tacoing. What I mean is your choices may be different with a DS because you aren't really using the wing much with a DS, especially when using a single. That is if you use your DS as I am at this time.

Are these tech divers using doubles or RB? Because if they're using doubles, and using their DS for buoyancy control, I'd like to know how they manage to compensate for the buoyancy swings that occur between full and nearly-empty cylinders.

Yes, with doubles they still may add air in BC the difference is these guys use the DS as their primary bouyancy device.

I hope you to not interpret my disagreement as in any way condemning, insulting, or lauging at you ... I agree with you that such things are not the way to conduct reasoned conversation.

I don't mean to imply your disgreement was one of these things, it just seemed a good time to mention it.

Thanks
