Your thoughts on dual bladder wing

[PfcAJ]

I've got a lift bag that has a dump valve on the top. I can inflate, and then control the bouncy with the top dump valve. I doubt I'll ever have a wing failure requiring this alternate, but it rolls up nice and compact on my plate, and provides a completely redundant lift source.

I'd like to see this maneuver if the elbow pops off your wing right when you jump in the water.

Isnt it now 'standard' for drysuit use?

Nope, it's not.

If your elbow pops off and your not in a drysuit your screwed anyways. I stick by my pillow lift bag and the ballon bag I keep bungee'd to my tanks. I'm not an ocean diver however so the sausage don't quite count for me, plus the bottom is not too far away...

With aluminum tanks you can kick your feetsies and not lawn dart to the bottom.

This is not a great strategy. It all sound fantastic until you need to deploy it in a hurry. I was a firm believer of the same approach until I tried some controlled scenarios and in most of them would have ended up dead.

Please consider another approach (2nd wing/drysuit), I beg you.

UTD official stance is balanced rig, strongly advocate not diving with wetsuits 7mm and thicker deeper than 30m but no prohibition against.

Don't know about the rest, but GUE says: balanced rig not drysuit perse. I dive in cold to moderatly cold waters and dive drysuit all year long. Up to about 20 degrees celcius water temperature I don't want wetsuit. Above that a wetsuit is nice, above 25 degrees I don't dive drysuit anymore.

But when I dive my steel D12, it's drysuit all the way. No matter teh water temperature. On deeper dives (40m) here in Europe it's also drysuit (cold and deep). Would I consider double bladder? No not really, I don't see the need for them given my rig. In tropical waters however I will dive alu tanks with different characteristics. Maybe there may be some advantages with double bladder.

I did my tech 1 in a wetsuit and I semi-routinely do those dives today wet.

I don't know why those loonies dive dry when it's a bajillion degrees out.

Because it's still 7*C at depth in the water....

I am an advocate for dual bladder wings.

Well I guess you need a drysuit then!
