another steel tank issue

[z0rk0l]

I have both tanks set up exactly the same, what can cause the right tank to go up with at the back? Same length boltsnaps same position on the tanks, bungee same length. Both tanks were around 70 bar. I don't get it. Am i missing something? Position of the D rings also the same..

It are 12L 232 steel tanks.

Inflator hose?

The inflator hose on the right tank is a bit longer cause I use it to inflate SMB with it aswell.

To me it looks like the left tank is the one that’s more floaty at the bottom
If everything else is balanced, and as you say a shorter inflator hose on the floaty side, my best guess is maybe some tension momentum is pulling from the valve side down and causing the bottom to rise

The shorter inflator hose is on the (from my point of view) left tank that doesn't feel floaty. The right tank has a slightly longer hose running to the dry suit

I agree with @Mobulai , looks like the left tank is floaty, not the right. Hard to tell in the video, but I would start with the BCD inflator/deflator his pushing the tank around.

Haha yes I am an idiot the left tank is indeed the one that is floaty

Both are sitting very far forward and under your shoulders instead of behind them. I'd move the bottom boltsnap towards the valve 2-3cm and try again. That will also make them not pivot upwards as much as they breathe down.

GETTING SIDEMOUNT TANKS TO BEHAVE THEMSELVES AND SIT WHERE THEY SHOULD

By Steve Lewis One of the least mysterious things about sidemount diving is how to rig a set of steel primary cylinders so they hang at divers sides as they are supposed to, rather than hanging pen…
