Go back and think again, and try to figure out what we are talking about , not come up with some deluded semantic bullshit that disregards the entire point, which is your rig needs to be balanced. What we have here is a "forest and trees" problem . -----Original Message----- From: Alex Vasauskas [mailto:surlyc@al*.ne*] Sent: Friday, December 22, 2000 8:24 PM To: techdiver@aquanaut.com Subject: Al vs. Steel Stages As far as I have been able to read, Al stage bottles are "good" and steel stage bottles are "bad" because steel bottles are supposedly relatively "too heavy for diving and comfort" and "unsafe". I checked the specs for the size of cylinder that would be appropriate for my open water diving. Here they are: Luxfer 48.4 cu.ft./3000 psi 21.15 lbs. empty -2.4 lbs. buoyancy full / +1.3 lbs. empty in salt water OMS 46 cu.ft. / 2640 psi 17.6 lbs. empty with valve -4.0 ...lbs. buoyancy full / 0.00 lbs. empty For approximately the same volume, the steel cylinder is lighter and neutral when empty, so I don't need extra weight to be balanced. The steel cylinder is lighter. So, is this just a unique example of the steel cylinder being the better choice, or am I missing something here? ------=_NextPart_000_0004_01C06CC0.C6C69E80 Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML><HEAD> <META content=3D"text/html; charset=3Diso-8859-1" = http-equiv=3DContent-Type> <META content=3D"MSHTML 5.00.2919.6307" name=3DGENERATOR></HEAD> <BODY> <DIV><FONT color=3D#0000ff face=3DArial size=3D4><SPAN = class=3D390290714-23122000>Yeah,=20 you have the wrong al tank, for starters, and you are assuming one gas : = air.
