<font color='#F52887'>do you have a Faber 10 litre dumpy and can you tell me how heavy it is? I am trying to work out my bouyancy while using stages and am trying to decide on what cylinders to use. I am weighing up the air requirements and weighting of kit and your help would be appreciated. I am going to do my normoxic next year and think that I would need at least a 10litre stage used along with a 7litre for high O2 mix

unfortunatly Faber do variable thicknes walls in steel tanks so this might not be spot on but:

10ltr Faber standard:  11.3 Kg with valve

Buoyancy Full  Negative 2.3 kg

Buoyancy Empty Negative 0.75kg

So using a 10ltr allowes you to remove 0.75kg form your weight belt

<font color='#F52887'>Thanks, do you use a calculator for working this out or just do the maths? I know there are some online and excel-based calculators around.

No. I have the data sheets for Faber, Luxfer,Catalina Heiser and Seagate tanks so I just look them up.
