Double Bladder Wings

Dominic,YOU ARE WRONG! you obviously have little or no idea what you are talking about. Reeve is correct, and I have better things to do with my life.

First, I am not getting involved in the squabble but here is my opinion
I used to dive a double bladder some years ago when it was thought for trimix diving it was necessary (before it was realised that some people outside the US dived in drysuits) but changed to singles some time ago as all that was needed for use with a drysuit.
When diving doubles I had all the connectors the same type. I only used two hoses, one on the left post feeding the primary bladder and one on the rght post slightly longer so that it ran down a sleeve on the secondary and then to my suit.  In the event of a problem with the primary I had my suit and if that was burst I could unclip the suit inflator and attach it to my secondary bladder.
That gave me three forms of bouyancy each of which apart from the secondary bladder could be fed from both cylinders.
As I use a travel wing for abroad and only use my main wing for drysuit diving I eventually binned the double bladder and went single as I considered it unneccesaryily complicated for the minor benefits it gave me normally.
 The point to remember is that there is no right or wrong answer for kit config, only lots of different opinions

RJ,

I feel it is necessary to point out that I was not in any way advocating any particular kit config. I like a dual bladder wing, but this is my choice, I respect other peoples right to choose the config. they want. It was not nor will ever be my intention to tell someone what they should use, but I will always give an opinon when asked. My arguament with Dominic was about one single point, namely the ditching of ones weights.

All the best,

Andrew

<font color='#0000FF'>Gentlemen, can I ask why you are in this position in the first place?

Personally, I dive wetsuited with enough weight that I am neutral at more or less all stages of the dive and therefore put absolutely no air in the wing at all, ever. Suit compression is noticable (just about) at 30m in a 3mil shorty but nothing lung volume wont sort out and the cyls would have to be virtually empty before they have a major effect. Wing problem, what problem can it give me if i dont use it ??

Perfect weighting (6 pounds) works !!

Quote[/b] ]No, I just keep my options open by keeping lead in pockets so I can ditch as much or as little as I like.

have you got a Dgps lat &amp; Long for this statement , i'm quickly running out of lead &nbsp;


BTW .

Nice debate from You and Andy.

BUT

Personally, and i mean PERSONALLY &nbsp;i have to go onto Andy's side about ONLY dropping lead in a emergency....... If i was on the bottom at say 50 mts and someone tried to undo my weightbelt to get me POS Buoyant, i feel that that will be pi$$ed off with the feel of cold dive knife steel ripping into their drybag. Having said that , I WOULD fill a goody bag with rocks etc , dump weightbelt , dumping rocks as needed.......

HOWEVER, what you didn't really explain was ......... HOW MUCH LEAD YOU DUMPED,,,, and i think Andy P is the same as me in thinking that you are dropping 2kg block weights at each time ,,,,,,,, when you maybe dropping 100 gram trim weights ....

Absolutely. Same here - that's why I don't use a weightbelt.

One kilo at a time until neutral or only slightly negative (not positive) buoyancy is established.

That way you ascend effortlessly at a safe rate rather than having to swim your negatively buoyant self up for several minutes, with the concomitant increase in on-gassing that exertion would result in..

One thing I have not seen anyone mention, I have a double OMS wing and run an inflator from each post to the wing but leave the right hand side disconnected. &nbsp;I have seen the inflator get of get &quot;lost&quot; between the twinset and me and I would hate to think of it getting stuck in a way that the inflate button would get depressed. &nbsp;You would never get to the damn thing... just an idea

Dave,

You are totally right, as a thought I have mine clipped to a chest D ring on a 3&quot; bit of line, that way I always know where the pigging thing is and can use it to some effect if it hits the fan, the Diverite does not have a pull dump on the RHS hose which is why I give it enough slack to raise it up.

Take care,

Andrew

I dive a dual bladdered wing as i dive wet alot and carry no lead as twins and a stage are heavy enough. i leave the 2nd inflator disconnected as it could cause confusion if one stuck open by the time you realised which one you would be accending v quickly.

you are loosing this one mate...

give up while you still have a little dignity.

how can you stand there and say that you have bolted your weights to your kit and "your dry suit will help you out".

the cuffs and neck seal is not the most durable material in the world.....

for the record
i dive with a twin bladder, and the connection is always ready to go.

i would say try and see what you think friend.
