You have GOT TO BE KIDDING!- New Aqualung BC

[Splitlip]

What does the animation show Mike? A diver in a good trim position. What happens when you use the lever? He goes up slightly and down slightly. Pretty easy to understand. How would you illustrate it better? Their point is to show how you can use the lever to adjust buoyancy at depth.

I think the little animated diver demonstration is (incorrectly) illustrating you use the lever to adjust depth (not buoyancy). And we all know that is not what a BC does. It compensates for buoyancy changes which result from depth changes as well as buoyancy changes initiated by wetsuit compression/expansion and change in weight of gas etc.
As others have said, if one is neutral and adds gas to a bc he can be in for an uncontroled accent.
As I said before, my problem is with the elevator analogy. Call it a new fangled inflator/deflator mechanism maybe. (That and a remote deflator (push rod) device which I see as a potential for problems.)
And true, any experenced diver would know you shouldn't use it the way the add implies and the way the animation demonstrates. However some uninitiated newbe might end up blowing his money on something like this and not put the money towards something really important like food, rent or a spare air perhaps.

First the double-hose reg and now this. Hog rigs are sounding better and better every day...

sorry i didnt read the whole thread so if this was already dicussed please ignore it
but i think that its just a standard inflator with 2 buttons combined into a lever and that the company just used the wrong words in the ads
up should be inflate and down should be deflate.
i also understand the added entaglement hazard and another con i see to this is that with standard inflators you have to use it no matter what(if you want to add air) so in an emergency you know EXACTLY where it is and its almost second nature to diver, or it should be if you dive a lot. with the oral inflator in a pocket i can see more trouble for rescuers trying to blow up a divers jacket if they are out of air and just a increased state of panic to a diver than cannot find the pocket or can budge a stuck zipper(if thats what closes the pocket)
i would still like to try this system on a shallow reef dive in warm waters some time

Marketing people would tell you that sugar was made of ground up fairy wings if they thought people would believe it and buy more sugar.
R..

Are you saying that...............................sugar is NOT made from ground up fairy wings?

Why show anything at all? Certified divers should be able to figure it out, right?

Oh, it's easy to understand. The animation clearly shows that aqualung, as an organization, either doesn't know how buoyancy control works or they are lying about it.

It's complete fiction. As has been pointed out, if you are neutral and add air without making further adjustments, you're going all the way to the surface.

Aqualung either thinks or wants us to think that the lever controls depth rather than buoyancy. Yes, any certified diver should know better. Anybody who has been to school where they teach science should know better. So, does aqualung not employ any certified divers? Do they not employ anyone who has been to school?

Maybe they're just kidding.

Maybe they're just kidding.

I think it's safe to say that it's a joke.

I like the part about "push-rod technology, as found in aircraft." Yahoo!

It's worse than you think, Dave. Fairies can't even fly.

LOL. Well, there's always "pushrod technology."
