I bought a Sherwood 100cf cylinder today. I went to this page:
http://www.sherwoodscuba.com/product.php?product_id=176
to get the buoyancy characteristics. It says that the 100cf tank has buoyancy of -5.3 lbs when full.
According to this thread:

dry air weighs 0.08 pounds at room temp, which gives me an air weight of 8 pounds in the bottle when full.
Am I doing something wrong, or does that mean that this steel tank is 2.7 pounds positive when empty??
