New DSS Torus Wing...

[zach5150]

Hello all...
I just recieved my new DSS singles setup. I went w/ their new Torus series 35lb wing. I dont have a tank at home, but when I manually inflated it, I noticed a tiny spot at the bottom where it seems there is no bladder....but, the website indicates it's an actual full circle style bladder.....

If Tobin comes across this thread, please dont take this as a complaint, more just a curious questions. I'm new to BP/W systems....

I expected a "circle" bladder to be inflated all 360 degrees.....anybody have any thoughts?
Here's a link to the description of the new wing....

BTW...I cant wait to get this thing wet this weekend! I've about got it all adjusted, and it seems like the perfect setup!

From what i understant about it , (Tobin will answer best) , there is a transfer area in the bottem there . One of the main benifits to the system is for air transfer , and light boyancy under the tank. When your diving there will hardly be much air in your BC at any giver time to warrent that area to have a large air pocket.

ZACH515o,

Just curious why you went with the Torus 35 instead of the 26. I'm considering both and for tropical diving considered the 26. What are your stats? Weight and type of diving?

I went w/ the 35 for a couple of reasons....I figured it would give me the most flexibility. It's not that much bigger (physically) than the 26, and it would give me more options down the road for colder water or maybe deeper dives.
I'm also a big guy...i"m 6'1, 285lbs...so the 35lb wing fit's well w/ my body's profile.
I'm a brand new diver...i've got a grand total of 6 dives, and the only BP/W system I've used was a guy who had an OMS 100lb wing all bungied up....but I loved the concept of the BP/W....and I figured if I was able to manage that ridiculously huge 100 pounder w/ a single, then the 35 would be perfect.
My instructor is a hard core tech diver, and his wing is 32 lbs...so that influenced my desicion a bit as well. Right now, I'm diving in Lake Travis (right now, just trying to get better!)...I plan on doing some spring and river dives as well...and have a Flower Garden trip planned in a couple of months and planning on Wakatobi in 2007.....

But, I'm not nearly as seasoned as most of ya'll.....so, I just hope I made the right decision.

It seemed from what I've read that the only disadvantage of the larger wing is floppiness (not a problem w/ either Torus), and physical size...(which is not a problem for me)....so I just figured it would give me more flexibility if i need it.

Ok...that makes sense...thanks!

The bladder is full circle, and air can more across the lower cross over,but the bladder is constrained in the lower cross over, this is to prevent the wing from pushing on your butt.

This may be a bit difficult to explain in text only, but here goes.

An inflated wing in cross section is basically a tube. In a horseshoe wing the the tube is U shaped and In a donut it is well, donut shaped, but it is still a tube.

Tubes want to assume a round shape. This is true for both the outer shell and inner bladder. We did not want the wing to have a full round section between the bottom of the tank and your rear end. The way this is accomplished is to "quilt" the inner bladder.

Ever seen an inflatable air beb or kids raft? There are connections between the top and bottom layers, like a quilt. Without these "quilted sections" the air bed would be round like a beach ball when you blow it up.

In the lower arc of our Torus wing the bladder has a small section where we welded the two surfaces of the bladder together. This section does not extend completely across the entire width of the "tube", just in the center. It in effect creates two smaller tubes that will not turn into one large round tube when inflated.

If you still have doubts put a little water into the wing, like you were rinsing it. Rotate the wing and see if the water moves through the lower arc.

Tobin

Tobin,
Thanks for the explanation. That makes good sense....Since this is my first BP/W, I'm still pretty green. Thanks again for all the time you spent w/ me on the phone when I ordered (I guess that was you...not sure! ), and for the help here too!

I have a question about the realistic ability to vent air underneath the tank in normal diving position. People typically complain about having to roll with a horseshoe wing to get air out from both sides, but in a donut, if the bottom part is under the tank, how is air going to flow there anyway unless you roll; I do see an advantage if you're head down, then air could transfer from one side to the other. I'm sure this question has been somewhat flogged around, (maybe on that monstro knock-down thread with Tobin and Patrick from Oxycheq) but I'm wondering about the real-world application here. I understand the concept, but I can say from experience that I have to roll or get pretty head-down vertical to fully vent my travel wing, which is a donut.

Your are correct Mattboy. In my opinion it rare that air actually shifts from side to side via the rear dump, single donuts, double donuts etc.

The main advantage of a donut wing is the ability to "hide" a bit of the volume in the lower arc. This allows for a more narrow profile.

Our wings have been narrow profile from day one. The center panels of our singles wings, horseshoe or donut, have always been ~3" wide, not 8-9 inches wide as is the norm in the industry.

Narrow profile wings vent easily due to almost no tank wrap. Minimum tank wrap means the air in the sides of the wing is only slightly higher than the top arc of the wing when the diver is horizontal. This is not true of wide profile wings.

The very slight advantage of a donut over our narrow profile horeshoe was never worth the potenetial downsides of a 360 zipper, as is required when one builds a wing with a replaceable inner bladder.

What now makes donut wings worth considering is the new 22 mil bladder material. This thick tough material allows construction of a "sewn shut" donut.

This allows us to maintain a very narrow profile, provide a donut bladder, avoid a 360 zipper and retain the camband windows for easy "No STA" required mounting and demounting.

Tobin

Are you talking about the oxycheq or dive-rite travel wing?
