Sidemount weighting

[rjack321]

stage and deco bottles are not factored into weighting as they are ditchable. They are also right about neutral when emptied to normal pressures. You'd only have to ditch them if they were sucked dry

In the ocean, stages (if bottom gas) are usually sucked dry. If deco gas they could be emptied if you are forced to share deco gas. If you have to share bottom gas up to a deco gas switch, then have some elevated consumption cause the whole dive has already gone sideways, the last thing you need it to be is too light as well.​

Just a question:
How much weight should be added against each additional stage AL80 ?

Also, I use 8 kg weight with wetsuit as BM in salt water.
How much weight should I have if Turing to sidemount XDeep stealth tec with 2 stages AL80?

Don't guess.

Put on ALL your cylinders with them all near empty (20-40bar) and add (or subtract) lead until you are neutral in shallow water (where your wetsuit is least compressed)

@rjack321 fair, but I don't plan on them getting below 700psi/50bar and they're only about a pound positive with reg/valve/rigging, so not enough for me to worry about

fine, just I need only a rough estimation as I need to know the size I should buy for XDeep central weight pocket?

my body weight is 105 kg with 3mm wetsuit.My BMI around 30.
I used 8 kg lead weight. With one AL80.

I need to know my approximate weight in sidemount with XDeep stealth tec with 2 AL80.

Yeah about the same.

So with twin Al80's, drysuit, Waterproof Warmtec 200g undersuit and tecline side16 Avenger, I started off the course using like 12kg in fresh water, and honestly believed at the time that that was the bare minimum required to keep me neutral with 30 bar in each tank - since then I've got more comfortable, changed breathing patterns, and venting technique, and have reduced down to 8kg, with the aim of hopefully arriving at 7 or 6 soon. baby steps, but generally the more time you spend diving the rig over and over again, the lower you can go - though with a drysuit and buoyant tanks you'll never end up at much less than 6kg...
