Will This Wing Design Fix the Taco Effect? #askmark @ScubaDiverMagazine

Lenny Zimmermann
I've been watching plenty of your videos lately (including lots of older ones) and a common question I'd seen was if there was some way to get a single wing style that works for both single and double cylinder set-ups with the answer always being no with lots of good reasons you mention for why that is. However, it seems to me that with the main problem on a double-wing with a single cylinder being the “taco effect” has there not been a simple frame (like a baby backplate, if you will) that would fit to the inside of the wing to hold that inner part down with a single cylinder just as if you had 2 cylinders in there? Think of a butterfly set-up where the “wings” hold down the webbing on the inside of the double wing. Seems to me that might solve that problem or am I missing something? Thanks for all the great vids and advice!

The Polaris Mobi Flex Wing has an interesting concept. You can adjust the size of the bladder between single and twin configuration with a zipper. But I am with you, it’s better to have a dedicated wing for each setup.

I didn’t think about the inflator hose, although slightly offset should work, I would think. Even so I was thinking more like a form of single tank adapter that spreads out to the width of dual tanks to hold them flat, rather than using bungee to handle that. Sidemount, yeah, I definitely would rather go with a proper sidemount system, but for dual tanks (and just because it seemed to come up so often with folks asking about it) I would think it might work acceptably. Agreed it probably wouldn’t be perfect, though, and thus not sell well enough to make it worth doing

Yeah, I’ll message Huish, see If I can get my hands on a set. They’re Atomic so they’re bound to be good and they have the dropped diaphragm like the D420 which is another one of my favorite regulators

I’m sure there’s a way to make this work but it can’t be optimal. At the best it will be draggier but it will also have too much space for the gas you need in it so your centre of buoyancy will move more with trim change and it will be harder to dump. So use a single-cylinder wing for a single, a double wing for twins and a side mount wing for side mount.
