Scubapro/Faber LP 75.8 Chromemoly Steel Tanks

[Scuba Doobie Do]

I've been offered a Faber LP 75.8 along with this nifty catalog shot.
I want to buy myself a tank but I'm a bit of an air hog so I was hoping to buy 80-104ish CF.
How would this bad boy compare to an aluminum 80? Would I even notice the difference in capacity? How do they compare otherwise in the grand scale if bm singles tanks?

An AL80 is 77.4 cu ft at 3000, and this tank is 75.8 cu ft at 2400..... Not much else to be said...

cave fill the lp76 and your problem is solved. should be like 104 cf then.

Leisure Pro has the steel XS scuba 100's with the valve that shows whether they are on or off right now for 334. Thats a pretty good deal for that tank. Free delivery.

Actually there is more to be said. The cylinder has a plus rating so it is 75.8 cu ft at 2640 psi. I fill mine to 3000psi so it more like 86 cu ft.

What are the odds a cylinder not hydro tested since it's 95 date would still get a plus rating today?

pretty good if the testing is done correctly and the hydro tester bothers to check the ree value.

Agreed, the key though is the tester having the REE values. These cylinders (and many older cylinders) not have the REE value stamped on them. As such, one needs to provide them. I have the REE values for my cylinders via an email from Faber and Bud Allen who is the USA distributor. That email was good enough for my hydro tester.

Most if not all current LP steel tanks are at their rated volume with the 10% plus rating not their rated working pressure.

The interesting thing is these tanks (or at least the ones I have) never came new with a "+", so it ends up a periodic challenge to get the 10% overfill... (3300 & 2640 respectively). I even have instances where getting 3k on my MP71.4 is difficult.

YMMV
