Halcyon: On the other hand.....

[metridium]

Violated budgies aside, does anyone know why air shifting in the Explorer wing is so audible compared to the Dive-Rite Classic wing, which is the same size and shape?

My Explorer 55 is actually a lot larger then a DR Classic. I don't remember if you are talking about a 55 or not though. This size difference could have something to do with it. It could also be that the new Halcyon wings have a thinner tube behind the neck. The shifting of the air could now have more of a venturi effect speeding up the transfer. Heck it could be because of the Cordura inner bladder just being moved around. Who knows?

I'm not sure why but from my POV it is nice to have the auditory indication.

Yes, both wings are 55lbs, though the older one is a Classic-clone, not truly DR.

Good points.

The differences in effect really stand out. I used to dive the Classic-clone with an STA in tropical waters (ergo hoodless). Never really heard the air shifting in it, but the shifting in the Explorer is quite loud, even through a coldwater hood.

Could it be that diving the DR-clone with an STA prevented the volume of air-shifting experienced with the Explorer?

Why is that?

Just got back from Cozumel and the air shifting in the 18lb Pioneer is quite loud too.

Why this even warrants discussion, however, is beyond me.

...that way I can know that it is happening and how much is being transferred.


Hey Roak... welcome back... and you know how desperate we get around here for stuff to talk about.

Because I've never noticed it with my 36lb Pioneer or my 55lb Classic-clone, and I'm wondering why that is.

Also because it first appeared while I was using the autodump on my drysuit and the rear dump on my wing. From my experience with wings, it shouldn't have done that, so I feared a potentially catastrophic leak.

Now that I know it's apparently normal, I have no concerns. Maybe reading this will save some future diver a few tense moments, though.

Wouldn't you already have that feedback from the change along your lateral axis?

Sure... but I love to hear it too...
I just isn't a big deal... I was only trying to humor you metridium
