Why a scuba? I have found that the steel ones (lots cheaper than carbon fiber wrapped aluminum) are too heavy. Both require special fittings to adapt them. I would think without looking, that a specific PCP tank would be cheaper in the long run.

I have a Hill EC-3000 compressor. If you're a fellow Guild member, and you pass through Roswell, NM, I'll fill your tank as a courtesy (4,250 PSI limit).

If memory recalls, I bought the 88 cf, carbon fiber tank from Airbag, for $695 on sale. Tons of monied even then, but it has saved the day more than one. Oh!

With the price of 12 volt DC compressors, the need for large tanks is mostly a personal choice. This is one reason I also have a small back-pack sized tank for afield trips.

SCUBA is not the same as SCBA.

SCUBA usually steel or aluminum tank. Designed for underwater diving use.  3,000psi fill.

SCBA is usually carbon fiber wrapped aluminum tank, and encapsulated in epoxy. Not designed for underwater use. Designed for above ground use, typically for firefighters and others who need clean air supply. 4500psi fill. Huge difference for filling your rifles quickly and efficiently.

There are aluminum scUba tanks, but they are not wrapped with carbon fiber or epoxy. This limits their fill to about 235 BAR (3,400 PSI). Steel is used most of the time, due to their weight which lessens the amount of belt weight needed to "sink".

My issue with scUba tanks is their fittings—just another place for air to leak out!

Also when looking for tanks there is a 15 year lifespan on air tanks and have be tested every 5 years during that 15 year lifespan.
Out of date and it can not be filled by a business legally.
There are lots of out of dates being sold on Ebay Beware
