Tanks come as cylinder only valves are available separately.
Johns Quick Tip’s: Think before you buy.
I am often asked by divers who come into the store, what kind of tank I would recommend that they buy. Personally, I recommend a steel tank. Steel tanks usually allow a diver to shed at least 6 lbs. of weight from their weight belt, generally hold more air, and usually hold up better from a service stand point. I know many people want a lighter tank, but think about it, how far do you really have to carry that tank on land and a lighter tank in the water means you need more lead.
Yes, they are more expensive in the short term, however consider this: A steel 120 cubic foot tank costs about $150 dollars more than an Aluminum cylinder, now it will hold about 50 % more air than the 80 cubic foot Aluminum tank. Second the steel tank will allow you to remove 6 lbs. from your weight belt, improving your trim in the water, thus decreasing the air you use. This means that you can add probably at least 50% more bottom time to your dive. On an $100 two tank dive, 50% more bottom time equals about $50 worth of time in the water. In 5 trips the tank more than pays for the added expense.
If you are not sure the type of diving you are doing a bigger tank is not always better. If you see yourself getting into more serious diving instead of buying a large single tank consider a smaller tank. The reason behind this is if you are going to double the tanks up in the future a large tank might be too much. The other thing to consider is buying a manifold up front along with manifold plugs if you are planning to double the tanks up. This way you need to spend more money up front but when ready to double the tanks up all you will need is tank bands. This way you do not waste money buying single valves that you will just have lying around once you go to doubles.
