dropping weight when going to steel

[nips]

I currently dive AL80's and use about 16-18 lbs in salt water with a full 3mil suit. I just acquired 2 hp steel 80's and 1 hp steel 100... how much weight can I drop when i use these?

Here's a chart Scuba Cylinder Specification Chart from Huron Scuba, Ann Arbor Michigan
Look at the difference of the empty weights between the tanks you are swapping out. This will tell you how much you can change...assuming you are correctly weighted now.

That's about what I was using before I bought my steel '80's. I dropped 6 pounds when I switched from AL 80 to the steels. When I travel and have to rent AL's I up the weight back up to 16 and am good to go.

Most AL80s are about +4 when empty. Most common steel cylinders are between 0 and -2 empty. You should therefore probably be able to drop 4-6#. As suggested above, you can look of the specific buoyancy numbers for your individual cylinders and determine precisely how much weight you can let go.

Empty, the HP tanks are 2-3 pounds negative, as opposed to 4+ pounds positive for the aluminum tanks. Why not start with 5-6 pounds less, and go from there?


(The OP certainly can't complain about a delayed response to his question!)

about 4 or 5 lbs .....

Congratulations on your new cylinders. Here is the whole story.

Plan on 7-8 pounds depending on the rounding errors in your baseline and cylinders.

You are going to love those steel tanks!

I was able to drop 6lbs. going from AL80 to HP100.
