I am being an idiot and I can't figure the weighting changes between steel and aluminum.
I will be diving a steel tank this weekend that has the following characteristics.
Full: buoyancy -11
Empty: buoyancy -2
At least this is according to the manufacturer.
I know what the proper amount of weight to wear with my rig for an AL80.
Is the following correct then?
Since the AL80 has a buoyancy at 500 psi of +4.4 pounds positive and the steel is -2, then I take off 6 pounds of weight?
Also, does it matter whether I am in salt or fresh when using these figures?
When I get to 500 PSI I will do a real weight check at 15-20 feet in the water, I am just trying to get ballpark.
