Diverite Rec Wing and Singles

[ereediver]

Does anyone know if there are any scientific tests regarding the effects of drag using different rigs. There are wind tunnel test for air, and ship builders to hull tests in special tanks. It would be interesting to see similar tests using scuba gear. Call Mythbusters.
By the way I use a Rec wing. Hands down better than my old vest. Never had anything else, so some data like stated above would prove if there is a difference, or if it's all personal opinion and theory.

OK taco is what we here would call tank wrap.
I have never seen a taco (non diving kind) so the reference was missed entirely on me.

Picture of an actual taco attached. You can get the idea how the term originated.

I agree that personal preference plays a large roll in gear selection, but what good is it without having different data points to make comparisons? Have you ever used a narrow profile single tank specific wing before? Something like a Mach V, Razor, LCD,Torus, Blackbird, or Eclipse?

I ask because two years ago I would have told you how great the OMS 60lb bungee wing was for singles. Now that I've tried other options, I know how awful that wing is when compared to a dedicated singles wing like the Mach V.

I agree. I dove a rec wing quite happily for over a year before I tried a Mach V. Only then did I realize that, while the rec wing did indeed work, there truly is a difference with using an appropriately sized wing.

I still use the rec wing with small doubles (hp100s/al.80s), but I doubt I'll ever use it for singles again unless it's an emergency.

Sorry to jump in, I never tried rec wing nor diving doubles but I have a question (maybe silly): if using another bungee cord between the exterior of the wing and the holes in the BP will actually diminuate the "taco effect"?
I understand that this may create air pockets and trap some air in maybe, but will solve (somehow) part of the problem.
Anyway, a donut shaped wing will still be much easier to vent, using the rear dump, than a horse shoe shaped one which is obvious...

Tying the wing down to the plate with bungees is one method to prevent taco.

There are a number of reasons why wings can trap gas. It can be from a poorly designed wing; or using a larger bladder designed for a larger wing in a smaller wing. The larger wing is basically folded up in the smaller shell. This is a common practice in diving, but all OxyCheq wings have matching bladders.

I agree. Wings should have a matched bladder. That's why we have produced as many rf dies as we have.

And with a bit of creativity it is possible to produce more than one size bladder with a given die.

This photo is a little dated, we've added a few more, but here's a shot of our wing bladder dies, and a few of the other dies we use for SMB's and other RF welded goodies.

Hi

Recently bought a DR rec wing to use with singles - not ready to use doubles yet, however common opinion was that this wing can be used on both singles and doubles.

Now that I have read all the "single wing for singles, etc." threads on here I am starting to doubt my decision.

My question is - is the DR Rec wing appropriate for single steel tank cold sea water diving (i.e. wearing 7mm suit + 5mm vest, boots, etc). I am planning to switching to doubles but for another 6 months or so.

I have put together the harness and wing yesterday and have tightened the gusset control to its tightest (uppermost) position. According to a few people (and DR), this should help avoid the dreaded "taco" effect. Is this true?

Just wanted to get a coupld of opinions from those who either dived this wing on singles or have seen others in the water using them. Have I made a big mistake? Is it likely there will be a lot of drag in the water with this wing even with the GCS fully tightened?

Any input is much appreciated.

Thanks.

Hello,

The Rec wing is a great wing for certain purposes and many divers enjoy it's multi-use capability. However, we always recommend purchasing equipment that is designed for your main dive goal. The Rec wing is a higher-lift wing designed for doubles with the caveat that it can be used for singles. It is a great wing for tall divers as well. See more about matching a wing with your needs in our Solution Finder article "What type of wing do I need?" SCUBA Diving Equipment for Technical, Wreck and Cave Diving: Dive Rite, Inc - Solution Finder

Also, we have a remedy for those of you who get the "taco" with the Rec wing. See Lamar's BLOG of April 15th:
Dive Rite - Dive Rite’s online journal exploring the latest in technical diving

Let me know if you have any more questions or how we can help.

Best,
Kathleen

I was referring to the fact that in order to vent the wing properly you'll have to go in vertical position (head up). Venting a donut shape wing is easier in virtually any position...

That's not true. The air bubble in a wing seeks the highest point no matter what. You'd have to go somewhat vertical to dump via the inflater hose in any wing. To dump from the rear dump you have to go somewhat ass up, esp. if you're not quite horizontally trim to begin with (slightly head up).

The only difference is with a horseshoe wing, you may have to torque up a bit, then down, to move the bubble and vent gas from the side of the wing opposite the dump valve.
