    I know it isn't scientific, as the are variations is detail, but I just weighed some stages I use for bailout.

    Their weights, complete with stage kit, regs, gauges and ~200 bar of nitrox, were:

    AL40 10.6kg
    AL7 13.1kg

    They are not very accurate.

    However they are accurate enough to tell full or empty.

    So I have changed from normal gauges to buttons on most of my bailout regs. Well on 6 sets of them to be precise.

    David Wallace spent hours producing a pretty complete cylinder weight chart that showed neg or pos, compensation weights to add, that sort of thing.
    if anyone is interested I may be able to dig it out.

    I was looking for it online with no joy a few weeks ago - so yes please!

    If time permits could you post a photo of a 40 and 7 side by side?

    Here you go:



    The difference is more noticeable when they're viewed from above:

    The 7 ain't bad (if it's a 232 bar) and you don't notice it much, but the 40 might as well not be there. It's my favourite cylinder to cart about, but doesn't get a whole lot of use these days, as it's only really good for 15 mins of deco really, which makes it perfect for cheeky O2 deco or a drop of EAN50 off the back of a longer 30m dive, but not enough for a 50m gas dive.

    Mine gets about half a dozen showings a year now, but used to be the go to tin. As and when I do my next mix ticket, it will get used more again. Meanwhile it gets carted around as the emergency surface deco O2...

    7L Al 207bar is a good all rounder in terms of capacity, but not as nice to dive as the 40. Al80 is just big. It's OK with a Nitrox fill, but once half full, becomes a floaty bugger. Someone on here got it right a while back when they described it as like going diving with a bouncy labrador puppy...

    I still don't get why someone would choose 207 over 232 bar cylinder. Less gas and more of pain when filling as most compressors vent when they reach 232. Yes buoyancy characteristics have an effect but still both cylinders are small so easy enough to work with.
