I put together a set of steel 72s a couple of weeks ago and I just love them! They are sooo light and trim out perfectly.
For single tank rec dives I had borrowed a couple of LP104s from a friend (all of ours are doubled up and filled with mix.)
Then, since I had a some lp steel 72s that were not being used for argon I started diving them as singles.
Then I decided to go ahead and double them up.
Well they are just sweet! I have a 10# V weight between them and that is more than enough total weight with the 6# SS backplate.
Today I will dive them that way and Friday I will take the V weight off and dive with an 8# belt just to see which I prefer.
But the best part is this:
Yesterday I only filled them to 1500psi since I wanted to get them down to 500psi at the end of the dive to play around with weighting.
We did a 52 minute dive (max 128') and I was able to get them to 500psi (down to 450psi by the time I finished playing with the weights.)
I can do two dives with these little guys filled to 2500. But better yet... I can still do one dive even if my nitrox bank is down to 1500psi.
Using the single LP104s I always refilled the bank when the highest bottle got down to 2500 psi.
Since the 3 cylinder nitrox bank is at 3700psi when full... that means far fewer compressor starts per month.
I'm really happy with these little guys.
