Buying a tank, if you don't know what you're buying

[NAM001]

Does empty mean completely empty? Is a few hundred PSI at the end of a dive ok to store them for a bit?

air weighs 8# for 100 cuft. a couple of hundred psi is of no concern.

GRAB THEM if and only if you are using weight to stay down. your buoyancy will shift about 4-5# in the neg when you go to steel.
Also tha al80 is 77 cuft. the lp85 is 85. when you start doing things like rock bottom calc's you will be glad you have the extra 8 cubes. Quite often shops do not look at the tank and you get 3k fills on the lp85 and you end up with a good fill when cooled or up to about 95 cuft at 3k. If you are not using weight and you use these tanks you are asking for problems unless you get some more suit to off set the neg buoyancy. The issue of dumping lead for the tank moves the weight up to the center of the3 chest and not the hips. It however removes about 5# of weight that was once ditchable. Make sure you look at all the angles before you buy. Still 300 for the pair is a good deal. They will last you for years with minimum care. Oh and one more ting the lp85as are very close to the same height and weight as the al s80's.

Just a heads up, you're replying to a month-old thread. He bought the tanks 3 pages ago.
