Cylinders

Steel or Aluminium?

Steel cylinders are smaller for there internal volume compared to aluminium.

Steel cylinders do not get as buoyant as an aluminium one when below 120 bar, so you do not need as much weight.

Steel cylinders are at risk of rust if they get scratched.

Alumiinum are great if they are living on a boat as the are not at risk of rusting.  They also do not need painting.  They can still corrode/pit if they are not stored correctly.

You do need more weight when diving with Aluminium, so be sure you know what you are using.
