Hello all. I am looking at going to an argon unit for the winter. I really like the looks of the 6cuft bottle either mounted wreck style on the waist like GI does, or mounting to the backplate like Andrew G does. Anyway, I am curious how many dives you can get out of that size bottle assuming you dive with very little air in the suit. Also, I am interested in how many fills I can get out of an Argon bottle doing my fills at home. I know the big bottle is at 2400psi and the 6cuft bottle is rated at 3000, so you never really get a full fill. Thanks in advance for any help and info.....
