Every dive shop, dive boat, and scuba diver uses scuba tanks. We’ve noticed a great many distinct sizes and shapes while we have all utilized the Aluminum 80 cubic foot tank. Each of the”distinct” scuba tanks has a unique advantage/disadvantage, utilize, and price. How can you choose the best scuba tank?
Things to Know about diving tanks
The first thing to know about a scuba diving tank or canister is the fact that almost always the recreational diver will get it filled with clean air, not oxygen. This is contrary to what television programs would have us think! It is not an air tank – it is an air purifier.
When it was full of pure oxygen, diving deeper than around 6m and breathing pure oxygen could actually kill the diver!
What Is In It Then?
Believe it or not, only plain, pure, clean compressed air. Nothing fancy! Your dip facility will use a blower filter it to remove particles and water to suck in air and squash it in the cylinder so that there is a lot!
Is It Always Just Fresh Air?
A canister does not necessarily just contain air. Divers use nitrox or trimix to permit them to dive deeper and for longer and occasionally oxygen during decompression stops – but only more shallow than 6 meters!
What’s a Scuba Diving Tank Made Of?
The sound, and often heavy, tanks are made from steel or aluminum. Pick one up and you will understand by the weight that it is – the metal ones are much heavier. For this reason, divers in suits, that want more weight to correct the exposure suit’s positive effects, may often wear the heavier steel tanks to prevent carrying many weights that are loose.
How Long Does Your Air At A Cylinder Last?
This is actually a very complicated question. The deeper you go, the smaller the tank, the thicker you breathe, the tougher you are swimming, etc the shorter time you will escape a tank.
The dilemma is that it takes more air molecules to fill your lungs in-depth than on the surface due to the effects of pressure at depth. You are currently taking a lot more out of the tank with every breath – in actuality, 4 and 3 times as much sensibly.
Swimming difficult makes you breath harder and, of course, that a 12-liter cylinder carries a lot less air than the usual 15-liter cylinder. But, a novice diver should be able to make a 40 to dive as long as they are not currently going excessively deep!
Choosing the Ideal tank
Budget. The reason the Aluminum 80 tank is is it is cheap. But are the Aluminum 50, 63, and 100-foot components, so why is the 80 foot the most popular? It is just because it’s the very first Aluminum dimensions (really the second size), but the first 72 cubic foot Aluminum units were curved bottoms and somewhat taller.
Physical Size of this Scuba tank. It’s generally the length of the tank and not the diameter that will bother divers. With no dragging it across the boat 10, carrying the tank is a sign that the weight can not be carried by you or your arms are not long enough. The tank is too long if strength isn’t the issue. Or should you keep hitting your head and the bottom of the tank is bouncing at precisely the same time from your buttocks the tank is too long? The two main tank producers (Catalina and Luxfer) either make an Aluminum 80 tank that’s 3 inches shorter than the standard tank. They do this by increasing the diameter of the new tank, but it’s a little heavier. The Aluminum 63 cubic foot tank is 21.5 inches. A number of those steel tanks are only 20 inches in length.
The Air Ability of this Scuba tank. Why take back the atmosphere to the ship if your air intake is less than your dip friend? The foot is perfect if I am diving with pupils a smaller 50. If I am not diving than I use my 100-foot tank, while she uses the cubic foot tank. Choose the capacity that best matches dive objective your air consumption, and proper security considerations.
Weight and Buoyancy considerations. The significant disadvantage of Aluminum Scuba tanks is they have a tendency to become positively buoyant. The Aluminum 80 cubic foot tank could be around 5 pounds of buoyancy at 500 psi. The two Luxfer and Catalina make a newer neutral buoyancy Aluminum 80 tank to solve this problem. Of course, you might want to think about a steel tank. These metal scuba tanks do not have the buoyancy problems that are positive that Aluminum tanks experience and are approximately 20 inches in length. The drawback of the steel scuba tanks (3500 psi) is that they operate at higher pressures and not all dive operations can fill them. If any water or humidity enters the interior of the tank, the steel material tends to rust. The cost of the steel components can be 2 or 3 times the Aluminum unit’s prices.
What Safety Precautions Should Be Followed?
Clearly, take care when lifting a dive tank – it is heavy! But it’s also full of compressed air, so be certain it is not going to fall over. Be careful to not harm the top part where you plug into your labs, nor shed the o-ring. A tank shouldn’t be drained. Air inside stops which damage the inside of the tank and could cause rust.
Learning how to preserve the air in the tank
One activity gives you the skill of air conservation to slow how quickly you burn off the air on your scuba tank greater than any breathing technique that is available.
That activity is: dip more frequently.
The more you dive, the better scuba diver you become, the more skills you learn, the higher your comfort level underwater increases, and the slower you breathe while you’re driving.
Stating that diving frequency is your single most activity that affects your speed of air consumption is my personal opinion of course, and you may disagree, but consider what you gain by diving every opportunity you get.
As scuba divers we know lots of different ways we can use to slow down how fast we burn the atmosphere in our freshwater aquariums, so we can stay submerged for longer dive times, and see much more of the aquatic world we all like.
We know how to set up our dive gear to provide us reduced friction immunity as we stunt throughout the water.
We learn how to correct our buoyancy profile so we don’t always fight our degree of depth, which tires us out and which makes us breathe harder, and faster.
We hear about various procedures of breathing which helps us conserve atmosphere so we create longer dives.
Trainers, divemasters, and fellow divers discuss their personal atmosphere conservation fashions, and how the techniques they use give them much dive time you’d think they’ve gills.
Not 1 technique of breathing management, or any gear trimming method, provides you more dive times before you try it out, make sure it matches your personal diving fashion and comfort level, then use it enough times that it will become automatic habit for you each single time you put your dip gear and enter the water.
You’ve discovered that experience is the best teacher. I think others’ experience is the teacher.
However, you don’t truly learn anything until you internalize it by placing the knowledge to personal practice, get so comfortable with this that you master the method, and eventually make it second nature to you that you can do grand cayman underwater photography.
Then you continue using that procedure so it remains automatic.
