position of the tank

[muddiver]

I ask the question only to clear up what I learned in PADI which was that the tank always needs to align with the top of the BCD ;-)

There are BC out there, that even when correctly adjusted, will not hold a cylinder in the middle of a divers back while standing on the surface. I would speculate that the advice you received about cylinder placement in your basic scuba class might have been based on the old (very old) hard plastic backpack type BCs. Where ever the backpack was located, there the cylinder would be.

The solution to the issue is the ditch your modern soft back BC abd purchase your favorite flavor of Back Plate with a Wing. (I can't believe I just said that:shocked2

It wasn't aimed at you, it was an impulse response to the thread in general.
All the talk about positioning made me think of a joke that hit me funny.

That's all.

If I aim something at somebody I always quote the post.

i was trying to continue your joke, vacuums suck. and harleys are pricey but notorious for bikers so either yuppie or cliche biker. guess you missed it ohh well

My SSI class had us start the same way... start. It's a good place to put it if you have unfamiliar equipment, then adjust accordingly until you know what works.

One size does not fit all!

Two requirements for tank position (assuming it's on your back, not side mounts)
1) high enough so you can reach the valve
2) low enough so you don't bang your head.

The video illustrates a common problem for petite people.
A "super 80" (cu ft) aluminum tank was introduced for this reason.
It had the same volume as the std al. 80cu ft tank, but was shorter.

Very good post! I have always had problems with this. I have a neckless physique where my head is directly attached to my shoulders (short neck and raised traps). The lowest position I can tie my tank would be where I can not look straight forward during a dive. My head would bang the tank. Any ideas / suggestions would be greatly appreciated.

Side mount? Draeger Ray?

Possibly a shorter tank, like a HP80 or HP100.

As with most things in the PADI world, it is a good starting point, not necessarily the law.

Would that the tank position not be the same even in a shorter tank? It would be high up from the butt but the distance from the head would be the same no???

I can't believe that everyone missed the obvious cause of all her problems...........pink fins!
