So, the question that should be lingering in your mind right now is how to know which agency is the best. In this article, you are going to have your question answered in full by learning more about two of the most preferred diving organizations, PADI vs NAUI. In the end, you will be able to tell the emerging differences between PADI and NAUI scuba diving certification.
One thing you need to know is that for you to be considered a certified diver, you will need to complete the scuba diving course first. Most significantly, your training and certification need to be carried out by at least one of the recognized diving agencies/organizations that is authorized to issue certificates to the successfully trained divers.
Once an individual has obtained the scuba diving certificate, he or she will be able to dive anywhere. The certificate will automatically act as a diving license or rather proof of someone having successfully completed scuba diving training.
Therefore, the moment you become a fully certified diver, you may use your certificate to hire or rent scuba diving equipment from any shop. That is when PADI vs NAUI, two of the topmost diving agencies world overcome in.
Source: Why Some Scuba Divers LOVE PADI (No, Really!)
Professional Association of Diving Instructors or PADI is a US-based organization and it is indeed the biggest and most famous scuba dive certification organization worldwide. The agency has been providing various types of performance-based diving training since 1966. Over the years, this agency has spread all over and at the moment, it has centers throughout the world. Apparently, more than half of skilled and highly experienced divers in the whole world have received their training and certification from PADI. Here are some interesting facts about PADI:
• The project award was set up by PADI in the year 1989. This was established as a global movement for all scuba divers to offer protection to our ocean planet.
• For the past two decades, PADI has been averaging over 900, 000 diving certifications each year.
• PADI provides recreational training as well as some variations of technical scuba dive training
NAUI is actually the oldest non-profit scuba certification organization. It was started way back in 1960 in the US where it is currently based. NAUI has been at the forefront of promoting safe diving by offering the recommended diving courses.
The organization provides diving training that is similar to that which is offered by PADI. Currently, it is the second to PADI when it comes to issuing of scuba diving certificates. The following are some of the most interesting facts about NAUI that you should know:
• Al Tillman is one of the organizations founding fathers and he became the first instructor from this agency.
• Captain Jacques-Yves Cousteau was one of the first members to sit on the NAUI board of directors.
• The agency offers both technical and recreational dive training.
There are underlying differences as well as similarities between PADI and NAUI based on many factors. The bottom line is that both agencies offer outstanding scuba diving courses and certification that can make you stand out in the crowd. This means whichever agency you choose, you can rest assured that you will become a good diver.

PADI certification gives you an upper hand in exploring the underwater marine life if you are indeed an experienced and certified scuba diving enthusiast. This is only possible after enrolling and successfully completing the scuba diving course.
One example of such courses includes the PADI open-water certification. This type of training is regarded as the most common and one of the basic PADI certifications. Why is it considered to be the basic training under PADI certification? This is because the course is the first ever scuba diving certifications training that the newcomers are meant to enroll in order to be certified fully as scuba divers. From this basic course, the divers can easily qualify for the advanced diving courses just in case.
To qualify for PADI certification, you have to be 15 years old and over for you to start off with the PADI open water certification course. Apart from that, there is junior open- water training for kids aged between 10 and 12 years old. Once certified at the junior level, the kids can advance to standard level upon attaining the age of 15 years.
In addition to the age as a prerequisite for one to enroll for PADI Certification, your health status will also be considered. In other words, you need to be in good health for you to qualify for this training.
PADI open-water training requires you to gain diving skills and knowledge in three major phases. These phases include:
This phase involves learning the basics of scuba diving theoretically. During the training, you will acquire all important information pertaining to diving equipment sellers, relevant techniques and skills needed while underwater. You can either attend the training physically or take the course online.
This second requires you to learn basic scuba diving techniques through practicing diving in confined waters or swimming pools. The instructor will guide you on what you are supposed to do in the course of your training. The whole course takes five sessions, ranging from simple skills to advanced diving techniques. By the time you are through with phase 2, you are expected to have all necessary skills that are crucial for an open water diver.
This is the last phase and it will take you to the real diving in actual water such as in sea or ocean setting. Open water diving will take you across five sessions or less than that depending on your performance. This training requires you to apply and display all the techniques you learned in phase 2. Also, the instructor will assist you in building confidence through your training sessions. Once you are done with the training, you will take the final examination to test you if you’ve acquired all the knowledge and skills necessary for becoming a scuba diver. If you pass your examination, you will be awarded the PADI certification as an indication that you have qualified to become a scuba diver.

Being the world’s largest non-profit making dive training agency, NAUI can boast of decades of continuous and successful training of divers. The courses under NAUI are somehow detailed and that is the main reason for their success. Here, different diving certifications are offered according to the levels of skills and knowledge acquired at every level. Check out for the summary of NAUI Certification courses below:
This is the entry level scuba diving course where you will acquire all basic fundamental diving skills in open water. Upon completion of this level, you will get certification in open water to allow you to dive anywhere in the world.
Advanced scuba diving allows you to acquire skills and knowledge in various categories of diving. These categories include deep diving, night diving, and navigation diving.
This is the level for divers who are looking forward to specializing in various types of diving techniques. At this level, you stand a chance to learn eight different diving skills.
These courses come in handy to let you acquire certification that allows you to engage in a special type of diving without the need for supervision. These courses focus on skills like night diving, wreck dives and search and recovery among others.
Professional diving courses enable you to achieve teaching techniques that are likely to help you become an assistant instructor, instructor trainers, dive masters or course instructors and so on.
Even though there are over 50 agencies that deal with scuba diving, PADI and NAUI come out clearly as the most preferred and largest globally. From their differences, you can at least decide which one suits your scuba diving needs. But whichever your choice you make, you will come out a well-trained and certified scuba diver with all necessary skills.

It depends on a few crucial factors. Which makes it entirely inaccurate to answer how long does a scuba tank last with a definite answer like 20 or 30 minutes. Nonetheless, scuba pros will tell you that an 80-cubic-foot standard aluminum tank will last about 45-60 minutes before hitting reserve, on a 40-foot dive.
With those figures, you can estimate how long an oxygen tank will last on a 130 feet dive.
But before that estimate, here are the five vital factors that will affect the final figure:

Scuba tanks come in a variety of sizes. The aluminum 80-cubic-foot mentioned earlier is the most common of them all. It contains air, 80-cubic feet, compressed to 3000 PSI (pounds-per-square-inch).
For deep diving, it’s best to use such big tanks. The higher the internal volume, the more prolonged the cylinder will last underwater. However, the best scuba cylinder is the 12-liter one.
Remember, there are two kinds of scuba tanks: aluminum and steel. The type of container you own plus how well it’s maintained can also affect its oxygen holding capacity. The DOT (US Department of Transportation) regulates all scuba tanks, and each cylinder should undergo hydrostatic testing every five years.

Most diving cylinders get filled at 200 bar (3000 psi). There are others filled at 300 bar (4000 psi) or even more, but they’re rare. Always check a tank’s maximum working pressure because it determines how much oxygen it holds.
So how long does a scuba tank last in terms of pressure? You guessed it- The higher the psi, the more extended the dive.

While scuba diving, the deeper you descend, the more pressure around you increases. The pressure increase doesn’t affect the air inside your tank. Because the air gets compressed at high pressure and the container is quite rigid.
However, water pressure compresses air exiting the tank and flowing your regulator horses, plus second stages. For example, it takes twice the amount of air required to fill one cubic foot of space (at the surface) to fill the same space at a water depth of 33 feet due to compression. That means that you will consume twice the amount of air at 33 feet compared to your intake at the surface.
Therefore, you can’t answer how long does a scuba tank last without considering that you will take in a lot of air at 130 feet.
Many things that differ from person to person. And one of them is lung capacity. Usually, bigger people have more lung capacity than small-size individuals. Meaning that if two different sized divers with the same breathing rate scuba dive, the smaller one will require less amount of oxygen to last as long as the bigger one.
Because the bigger person needs more air to fill his/ her lungs than the small guy. Still, lung capacity doesn’t have to matter if you improve your breathing rate to control air consumption. Thus, you can accurately judge a person’s lung capacity by size alone.

While underwater, the more breaths you take (per minute), the faster your tank depletes. If you want your cylinder to last longer, you ought to breathe slower. And how do you do that?
Clear your dead-air space off carbon dioxide by exhaling longer. Contrary to popular belief. This carbon dioxide is what triggers the urge to breathe and not lacking oxygen.
Your body triggers the urge to breathe if the level of carbon dioxide in your lungs is high enough.
Nonetheless, other factors that affect your air consumption rate whether you exhale enough or not. They include buoyancy control, experience level, stress, and amount of exertion needed when diving. All in all, relaxed, deep and slow breathing will reduce your air consumption.

The simple answer is generally less than one hour.
Since an average scuba diving beginner, in calm water (80° degrees Fahrenheit), breathing normally, would take about an hour to empty an 80 cubic foot cylinder at 33 feet. It’s easy to double this time if you train yourself on the economy of motion, plus breathing/ buoyancy control.
