More Information

The advantage of this high pressure mini tank is it’s small size and it’s designed for depths up to 40 feet. Diving time with this tank is up to 10 minutes, but if you are more thrifty, it will be longer. Also, we said it is easy to charge, but we didn’t say how. Namely, you have to pump oxygen manually with the pump which you get in the package. That is a good option because you can fill the bottle and dive again immediately after pumping.

And also, to mention this, you need to place a bottle directly on the mouth. So you won’t need a backpack or some belt for it. Someone may think the tank will bother you during the dive, but trust us, it won’t because it’s small and very light. The same case is with scuba masks, until you try it, you won’t know is it good.

This mini scuba tank is very similar to the previous one, but this one comes with a few more chances, so the price is a little higher. Unlike the previous one, Dxdiver comes with a case that can hang on the belt, but unfortunately, it does not come with a pump, so you won’t be able to fill it on the beach.

More Information

Also, you can choose the capacity of the dive tank between 1,9 and 3 liters. Also, with a tank comes a valve which you can mount a breathing pump. That’s a pretty good thing because you’ll be able to tie it to your waist instead of breathing directly from it.

The only thing you are missing is the pump for oxygen filling. With the help of it, you will be able to recharge it immediately and continue diving. You can also buy a compressor that fills up the bottle very quickly, but it is a little more expensive, and will you need electricity to make it work.

The fourth item on the list is quite different from everyone else. Namely, this product consists of one large tank (primary), and one small scuba tank (auxiliary).

More Information

DXDiver made these two tanks of stainless steel, so it may be harder to carry them. The material is not to blame for being dense, but because you carry two bottles. Another good thing is that you can connect both bottles to one pump. You also can choose the speed of the oxygen from the bottle.

Materials

We always listed the best materials in the essential features of every review. Now let’s explain why is it necessary for the best scuba diving tanks. First, it needs to be lightest as possible. Why? So you don’t get tired while diving, because that’s not the goal. The goal is to enjoy the research of the underwater world. Second, the material must be as reliable as possible.

As you know, these bottles use compressed oxygen, so there is a lot of pressure inside scuba tanks. That’s why it has to be of solid material, so it doesn’t explode. And third, the container must be resistant to corrosion. But, you do not have to worry about it, because all the bottles on the list are corrosion resistant.

Oxygen capacity and duration

You probably know this, the bigger the bottle is, the more oxygen it will fit into. Therefore the diving time will be much higher. Of course, the goal of every customer is to buy a smaller bottle with as much air storage capacity. Also, the duration time of the oxygen in the bottle will depend on the bottle type which you want.

Namely, there are two types you need to know about. The first is a big tank. Divers usually worn on them the back, they are a bit heavier, but you can dive with them for longer time. In essence, these are the bottles used by professional scuba divers, and diving time with them is over 30 min. The other kind is the small bottles which can be used for 10-15 minutes. You can tie those small bottles to the waist, hold them in your hand, put them on your back, or even put them directly on your mouth because they are very light.

Weight

The weight of the tank will depend most on the material of the cylinder and its size. As you know, today, we make bottles from lightweight materials like aluminum, such containers are lightweight. Before these aluminum bottles, they made the old bottles of heavy metals like steel and iron. Fortunately, the use of these heavy materials stopped and changed to the use of lightweight ones. Also, if air capacity is large and its size will be larger, so the scuba tank will be more massive.

Price

As you may have noticed here, all the features depend on each other. That is not the case with dive blades; for example, the price will not rely on the size. But let’s back this on review, the cost of any diving tank will only depend on the cylinder material, and will also depend on its capacity. Of course, there are exceptions. There are small diving tanks on our list that cost far higher than some large scuba tanks. As always, your goal should be to buy a cheaper and high-quality diving tank.

Types

There are two types of scuba diving tanks — the first are small ones with a capacity of up to 2 liters. And large ones with a size bigger than 2 liters. You see, there are much more types of scuba tanks, than scuba diving flashlights ,which have more varieties. Beginners usually buy those small scuba tanks because they are easy to charge and last for 10-15 minutes. Good thing, you can pump them with a tire pump. And professionals use the large ones, they are a little heavier but have higher oxygen capacity and therefore last longer.

Filling tank with oxygen

We may not provide this service, but it is essential for the best diving tanks. You know that renting diving equipment is very expensive. Most useful for you is to give $100 for container once and before diving to recharge it. It costs $5 to $10 (depending on the capacity of the tank). It’s about the big ones, and for the little ones, it’s another story. You can fill them the same way as large ones, but you can do it manually with a pump for a tire. It’s also the cheapest way, maybe a little harder, but for a 15-minute dive, it pays off.
