The 10 Best Diving Tanks

The Faber FX Series 100 (about $380) can be filled to 3,442 PSI, which is more than most other models on the market, so it should allow you to squeeze out a few extra minutes of underwater exploration. Plus, it offers a long-lasting steel construction.

Coming in a vibrant yellow or blue, the Sea Pearls 80 (appx. $189) will definitely be noticed by other divers. All units come with a current hydro testing and visual inspection sticker, so you won't have to waste any money or time getting those done.

At just a touch under 21 inches tall, not including the valve, the Faber FX Series 80 (appx. $300) is a good choice for shorter users and anybody else who finds that larger options feel bulky and unbalanced on their back. It is also rather lightweight, at just 28.6 pounds.

The Luxfer Compact 80 (appx. $269) is neutrally buoyant when empty, though to achieve this in an aluminum model they had to make some compromises, namely that the walls are very thick and, at 34.7 pounds, it is heavier than most others when on land.

The Dixie Diver Bailout (about $399) is an all-inclusive pony bottle package that comes with a nylon belt and sleeve, a button pressure gauge, and a regulator. It even includes a fill adapter, so you can use one of your own tanks to keep it topped off.

If you already have your main unit and are looking for an emergency backup, the Catalina Pony Bottle (appx. $163) is a good option. It comes in five capacities, ranging from six to 40 cubic feet, and all are equipped with a cool Genesis Scuba tank wrap.

The Cyl-Tec Silver (appx. $147) has an 80-cubic foot air capacity and comes with a combo valve that is compatible with both DIN and K-type connectors. Plus, the brushed aluminum exterior gives it an attractive look and stands up well to damage.

If you live by the Scout's motto, then you probably want to carry a large amount of backup air, and the 30-cubic foot XS Scuba Pony Bottle (about $192) let's you do just that. Its thick and durable walls should keep it in good shape, so it's always ready when you need it.

If there are multiple divers in your household and you want to eliminate any chance of arguments over whose gear is whose, the Catalina 80cf (around $250) can help, since it is available in several vibrant colors. It is suitable for up to 40-percent nitrox mixes.

There is no question that the Luxfer Limited (about $680) is expensive, but if maximizing your underwater time per dive is important, this is your best option. It has a 105-cubic foot capacity and is rated for 4,350 PSI, which almost no other model can match.
