OMS Wing and single Tank

Exactly, you get the right equipment to do the job correctly.

Of course only as defined in Rule #2!

It must be broke!"

I guess the other DIR rule is be independently wealthy or have someone else pay for all of that gear.

Right gear for the job.

Oh yes, so-so hand signals are fine because we have wetnotes.

hmmmm

You guys are doing decompression dives, right?

How far away is the nearest available chamber?
What is your backup when someone gets DCI?

No chamber on site? Why not?
BTW the Navy dive manual has a very good definition of 'on site'.
Get the right gear to do the job.

Oh never mind, just go back to your little cult.
And you can keep the flower.

Okay Pete,

Please explain to me why a spreader plate and wing are better/worse, or more desirable/undesirable than just a single wing?

a spreader plate is essential to eliminate the "taco effect" on a single tank. The taco effect can cause you to be unstable in the water as there is TOO much that can shift around. There are smaller wings, and I suppose that I could afford one, but why? The spreader plate sandwiches the wing between it and the back plate and stops that taco action. No more, no less. The big plus for me is the consistency between single tank and double tank setup. Other than the weight, my back plate and wings (or OMS IQ and bungeed wings) react the same whether I have a single tank or doubles in place. As I pointed out before, there are no moving parts, no extra failure points. Fred T even suggested using a sheet of lexan instead of a pre-bent sheet of aluminum. The STA would put enough pressure on the lexan to bend it into place and it would be simpler to fabricate than my aluminum version. If I didn't already have my spreader plate, I might have tried that.

I have had a Transpac with the junior wings. The jr wings had a buckle on the bottom outside edge that could clip onto the waist belt. It was to prevent the wrap around or "taco effect" that you refer to. I tried the wings with and without the buckle. I preferred the unclipped way and at no time did I feel that there was uncontrollable shifting of the air cell or myself. However, the junior wings are not to big for single tanks. I guess I could try using my classic wings with a single but that would be overkill. I use the right equipment for the dive. I don't think that modifying a piece of gear to make it kind of work for the task at hand is the best approach. You did not present a good enough reason to use more equipment i.e. an oversize wing and spreader plate versus less equipment sized correctly. When I dive singles it is a pleasure to have the minimal amount of gear needed.

junior wings. However, you have given me no compelling reason to spend another $250+ for something I really don't need or want. My system works more than fine for me, and I think I will keep it. I am quite comfortable with the setup that I have, and I don't have to get used to the eccentricities of two different wings. Minimalism has it's merits, but I prefer maximum safety. Perhaps when I win the lottery I will purchase each wing offered by Halcyon and learn the relative merits of each one.

I have answered the initial question as to how to use a wing with a single tank. I did it simply, without adding any additional failure points or task loading. I would love to hear how you would propose to solve this dilemma without purchasing another wing.

So you don’t want to have the optimal setup for your gear? You need it whether you know it or not.

No eccentricities, the proper sized wing behaves the same for doubles or singles.

Junior wings are not Halcyon. And it appears that you are bashing a product without having tried it. In other words you have not dove with the correct sized wing for singles. This is a point of contention that you keep getting upset about.

I have answered the initial question as to how to use a wing with a single tank. I did it simply, without adding any additional failure points or task loading. I would love to hear how you would propose to solve this dilemma without purchasing another wing.

The question was not how to use a wing with a single tank. It was the merits of using the proper sized wing versus using an oversized wing and extra gear. You did not clearly articulate the merits of having extra gear to offset the selection of the wrong piece of equipment. You think that because it has no moving parts or failure points that it is okay. My question is why bring it when there is a more optimal solution. Diving is not a contest to see who can hang the most crap on their rig.

Hmmm,

Sounds like the highly touted DIR advantages of using the SAME rig for ALL diving, and saving money by not needing to buy redundant rigs has gone completely out the window.

So there i was thinking about buying a normal back inflation bc until i posted for advice the other day and roakry set me rightly straight.....

I read and read and read....and after reading some more i figured that wings + BP were the way to go.

Due to the limitied selection here in ireland ( most dive shops only stock jacket style bc's and very few back inflation....and NONE stock back plate + wings :fury: ) i was forced to look to the UK.

Now i would like to know if the OMS backplates are compatable with most wings...the thing is that i don't really want to spend $700 on a double wing when i won't be diiving with a twinset (aka doubles) for a while. I would rather just get a single wing and upgrade when the time comes.

The way i understand it, the reason a lot of ppl go bannana's over bp/wings is that they can be modified easily as your diving becomes more demanding (or less)....so can the wings be changed without a new backplate and can you attach other makes of wings, say dive rite or custom divers wings to an OMS backplate?

Also some general comments about OMS either positive or negative are appreciated....


Oh yeah, newbie question...what is this DIR technology you speak of? i've read it everywhere and much is not clear since i don't know what it is...!?!

 

[The Chairman]

if you refer to rule #2. There are signifigant holes in their logic, BUT they can never back down in public and say "I see your system has merits". That would mean that others would be "Doing It Right" as well, and that is anathema to the DIR diver. I have been described as having a closed mind, and yet I have actually adopted some of their gear configurations and am considering others as well. However, I could never, ever ascribe to either Rule #1 or Rule #2.

BTW, did you see what wing was specified? Omar seems to have, but I guess I missed it. I did quantify what I did with my 55# wings when diving singles. Doesn't really matter, in that the question Omar asked doesn't seem as sincere in light of his subsequent replies. I think I was baited yet again, but thats OK, because it was not quite as condescending this time through.

And Omar, I am sorry if not being able to afford every wing configuration out there to meet every possible diving condition is considered "bashing a product". Heck, I want to buy a dry suit and become Trimix certified before I even think about buying a Junior Wing, whoever makes it. But it was good to assign me motives that I don't possess... muddies the water even more.
