Decompression stop for shallow dives?

[The Kraken]

My Dive-Rite "Venture" wind dumps beautifully in the horizontal position, that's one of the reasons I purchased it.

The dump valve is on the surface side of the wing when one is in the horizontal position. And, as far as I know, ALL of the BC dump hoses are connected to a vent which is on the SURFACE side of the BC/Wing when in a horizontal position thus putting the air inside of the bladder up toward the surface (air rises) and facilitates the escape from the vent port.

If your wing is dumping air "beautifully" then you are not horizontal.

The attachment of the inflalator on my wing when I am standing up out of the water is on my back, just above my left shoulder blade.

*IF* you are *perfectly* horizontal in the water, the air that is in the wing should be evenly distributed around the wing. If you dump air at this point you will not be able to dump all the air, or even most of the air - unless you drop your knees, moving the air bubble towards your head. This is made worse because a wing is a U or O shape rather than being a perect air pocket.

So I guess what you are really doing is a "horizontal-except-when-I-dump-air ascent"

sorry, you can't argue against physics.

Your wrong...people have told you your wrong and you still don't get it. Just because you can't do it doesn't mean it can't be done.

Whatever . . . regardless, all of the little bubbles go bubbly, bubbly bubbly alllllll the way up to the surface, oh my !!!

Hey TX-

Can you explain what that little thingy is with a string on it near the base of the wing? Ever use one of those? You should try it sometime. It's amazing how well it works when you are horizontal. And you know what's more amazing? It's doesn't break the law of physics!!!

Detroit Diver,
It's not like you to be so harsh - are you having a bad day?

TX,
As a novice I don't go vertical when dumping air I'm basically horizontal but I wiggle myself so that my left side is slightly higher than my right. I do it this way coz I'm rubbish at anticipating buoyancy changes so I end up that way more by accident than by design (in a drysuit) - in a wetsuit I'm horizontal (ish!) . That said, those experienced with the wing are horizontal (no ish).

 

[detroit diver]

No, only with this guy. He likes to bash anything DIR, yet sometimes doesn't have a clue about what he is writing about. And when he's told that he's wrong, he just keeps pounding away.

One point I'm a little confused about is the statement below:-

"I also have a fundamental issue with using breath control to ascend as you are filling your lungs, holding your breath and then waiting till you start to go up. Do that improperly near the surface and say hello to Mr AGE."

When putting up a blob (DSMB) with a spool, don't you have to be slightly (and I mean slightly) positive to help you wind in the line with the boltsnap. If you don't you end up fighting the line.
What's holding your breath here TX? You never hold your breath - you just relax , breathe slowly in, blow slowly out just enough to rise slightly - why would this be an issue?
Or am I wrong here?

 

[detroit diver]

You're absolutely correct on this issue of "holding your breath". It's a matter of inhaling deeply with your airway open, holding it, and then releasing.

As for the DSMB, once you're sent it to the surface, you ascend slowly in the manner above and wind as needed. As you're not rocketing to the surface, you should be able to do this in a very controlled manner. That said, it does take practice (like anything else).
