FAQ recreational diving

Snorkeling seems easy, do I really need training?

You probably don't if you're comfortable in the water. However, even if you are, PADI Professionals and snorkeling tours arranged by a local PADI Dive Center or Resort can take you to some of the best snorkeling spots.

I've always wanted to learn to scuba dive (or snorkel). How do I get started?

The best way is to visit your local authorized PADI Dive Center or Resort. There are more than 4400 worldwide. Just visit our Dive Center and Resort Listing to find one close to you.

Is learning to dive difficult?

No, it's probably easier than you imagine -- especially if you're already comfortable in the water. PADI's entry-level course consists of pool diving, knowledge development and open water dives. The course is performance based, meaning that you progress as you learn and demonstrate knowledge and skill.

How long does it take to become a certified scuba diver?

PADI courses are performance based, which means that you earn your certification when you demonstrate that you've mastered the required skills and knowledge. Because some learn faster than others, course duration varies. For example, the PADI Open Water Diver course can be split into five or six sessions over as little as three days to a much as six weeks.

How old do I have to be to become a certified diver?

You must be at least ten years old to receive a Junior Open Water Diver Certification. Ten and 11 year old Junior Open Water Divers must dive with a certified parent, guardian or PADI Professional to a maximum depth of 12 metres/40 feet. 12 to 14 year olds must dive with a certified adult. At age 15, the Junior certification upgrades to a regular Open Water Diver certification.

Are there any special qualifications or considerations to participate in a scuba class?

No. Generally speaking, anyone in good average health and at least 10 years old can participate. You will, however, complete a medical questionnaire. If anything on the questionnaire indicates a reason to be cautious about diving, you'll need check with a physician to make sure you can dive.

Do I have to be a great swimmer to be certified as a PADI Open Water Diver?

No. You need to be a reasonably proficient swimmer and comfortable in the water. You must swim 200 metres/200 yards nonstop, without a time or specific stroke requirement or a 300 metre/yard swim with mask, fins and snorkel. You'll also perform a 10 minute tread/float

Is scuba diving expensive?

No. Like any hobby or recreation, you can invest however much you want, depending upon your interest level. Because most dive centers and resorts rent equipment, you can invest in equipment over time, renting what you don't have. There's probably good diving not far from where you live, so travel costs can be flexible enough to accommodate even the tightest budget. Most people find the costs of scuba diving similar to the cost associated with snow skiing or mountain biking.

What equipment do I need before I take scuba lessons?

It's best to check with your instructor ahead of time to see what equipment is provided in your scuba course. Generally speaking, you'll want to own a mask, snorkel and fins. Your local PADI Dive Center or Resort can help you select quality equipment that fits properly. Most scuba equipment is very durable, so you won't have to replace it often.

What's in a scuba tank? Oxygen?

Recreational divers breathe air, not oxygen. The air in a scuba tank is like the air you're breathing but is also filtered to remove impurities.

How long does a tank of air last?

Since people breathe at different rates and as you go deeper you consume air faster, there isn't any one answer. Because of this, divers carry a gauge that lets them know how much air is in the tank. However, divers in calm, warm water from 5-10 metres/15-30 feet can spend about one hour underwater with an average tank.

My ears hurt when I dive to the bottom of a pool. Won't they hurt when I scuba dive?

Your ears hurt because of the water pressure on your eardrum. In your scuba course, you'll learn simple techniques to equalize your ears to the surrounding pressure, much like you do when you land in an airplane.

In the movies and on TV, divers are always running into sharks or eels. Should I be concerned about marine animals?

Most aquatic animals are passive or timid. A few do bite or sting, but you can avoid these by not touching them. Divers aren't natural prey for sharks and therefore shark attacks are rare.

Is scuba diving dangerous?

No, but there are potential hazards, which is why you need proper training and certification.

I need vision correction. Is that a problem?

No. Wearing soft contact lenses shouldn't be a problem while you dive. However, if you wear hard contacts, you'll want to dive with gas permeable lenses. See your eye doctor for more information. Another option is to have prescription lenses put into your mask. See a PADI Professional about this service.

If I have been diving, how long should I wait before flying?

The dive medical community offers the following recommendations for flying after diving, whether you’re using the RDP, another table or a dive computer:

For Dives within the No-Decompression Limits

Single Dives - A minimum preflight surface interval of 12 hours is suggested.
Repetitive Dives and/or Multiday Dives - A minimum preflight surface interval of 18 hours is suggested.

For Dives Requiring Decompression Stops

A minimum preflight surface interval greater than 18 hours is suggested.

With all dive tables and computers, no flying after diving recommendation can guarantee that decompression sickness will never occur. These guidelines represent the best estimate presently known for a conservative, safe surface interval for the vast majority of divers. There may always be an occasional diver whose physiological makeup or special dive circumstances result in decompression sickness despite following the recommendations.

Scuba diving sounds exciting, but I'm not sure if it's for me. Can I try it without signing up for a course?

Absolutely. The PADI Discover Scuba Diving experience allows you to make a shallow scuba dive supervised by a PADI Professional after a short pool session. This usually takes a few hours. Or, you can try the PADI Discover Scuba experience that lets you try scuba in a swimming pool.

How do I find out more about diving or snorkeling?

Visit your local authorized PADI Dive Center or Resort for complete information about PADI programs and how you can get started.

I'm already a scuba diver and I've lost my certification card. Can I get another one and how long does it take?

To replace a lost card you can go to your local PADI Dive Center or Resort, or you can go to the replacement card area at padi.com. It takes about two weeks to replace a certification card so if you are diving sooner than that, have the PADI Dive Center or Resort you're diving with call PADI. PADI will transmit your certification information. If you were certified after 1984 in PADI Asia Pacific, PADI Americas, PADI Canada, PADI International Limited or PADI Europe territory, PADI Dive Centers or Resorts can usually verify your certification through the computerized Dive-Chek system at any time.

I'm a certified diver through another training organization. How can I become a PADI diver?

Start by visiting an authorized PADI Dive Center or Resort and present your certification card. After an assessment of dive skills and knowledge, a PADI Instructor will guide you to the appropriate course. Here are some general course prerequisites:

PADI Adventures in Diving program and most PADI Specialty courses - An entry level scuba certification and documentation of at least four open water scuba training dives as part of the certification course completed.
PADI Rescue Diver course - Certification beyond entry level and documentation of at least 20 open water scuba dives demonstrating experience in deep diving and navigation.
PADI Divemaster course - Certification from a recognized training agency specific to scuba rescue and documentation of at least 20 logged open water scuba dives demonstrating experience in deep diving and navigation. Additionally, you'll you need a CPR and first aid certification within the past 24 months and need to be at least 18 years of age.

I'm a scuba instructor certified through another training organization. How can I become a PADI Instructor?

Contact an authorized PADI Career Development Center, 5 Star Instructor Development Center, or Course Director to determine where your instructor rating fits in the PADI System of diver education. You will be required to take the Instructor Exam following your initial training, which is a two-day evaluation of teaching ability, dive theory knowledge, water skill level, understanding of the PADI System, attitude and professionalism. Success at the IE means PADI Open Water Scuba Instructor certification.

FAQ technical diving

1. What is technical diving?

Technical diving is the use of advanced and specialized equipment and techniques to enable the diver to gain access to depth, dive time, and specific underwater environments more safely than might otherwise be possible.

2. What does it involve?

First you must understand the basics, beginning from safety. Safe divers are divers who take themselves seriously. Accepting that no-one can learn everything at once, or learn it just from books. Developing skills slowly, over years a bit at a time and that is what makes a good technical diver too. You have to ask yourself some questions. Why do you want to develope your diving skills? What are your prepared to sacrifice? How much are you prepared to learn? How long are you prepared to spend learning.? If the answer to these questions is something like

Because I want to go deeper and find more brass....

then it is not the sport for you. But if the answer is something like

Because I want my diving to be safer and my bounderies to be stretched...

Then you are on the right track. Technical diving, whether it's using nitrox or other gas mixtures to increase depth or bottom time or developing sage solo diving or deep diving techniques, is potentially dangerous as letting an untrained driver loose in a Formula One car. Before you are considered sage to go out on the track there is a great deal to learn, and you should never stop being prepared to learn, never assume you know it all. You never will. And before stretching your underwater horizons further, you must first learn to cope with yourself.

3. What is Nitrox?

Nitrox is a mixture of oxygen and nitrogen at required level depending on the type of dive involved. Air is considered to be a nitrox mix. Nitrox mixes which are hyperoxic (contain more than 21% oxygen) are variosly known as; enriched air, enriched air nitrox(EAN or EANx) or SafeAir®. For most of the part, sport divers will only be interested in hyperoxic nitrox mixes.
SafeAir® is copyright of ANDI and refers to any nitrox mix with an oxygen percentage between 22% and 50%.

4. How can nitrox be used?

It can be used as a gas for a normal dive, it can be used for decompression or it can be travel mix.

Using it as if you are using AIR
In this way you are increasing the safety margin extensively, because by increasing the oxygen level you can reduce the ongasing effect of the NITROGEN, thus increasing your bottom time. It is important to know that the higher is not always the better. WHY? Because the more you increase the percentage of oxygen in your mix the shallower the dive must be because you are increasing your partial pressure of oxygen which can result in an oxygen hit.
Decompression GAS
If the percentage of oxygen is in the region >40 % than it can be used as a decompression gas. It is safer to use it as a decompression gas because it flashes the nitrogen faster. Remember That in an emergency 100% oxygen is used and you must know why.
Travel Mix
This system is used when you are carrying more than one cylinder one with a mixture of the bottom and one to be used while traveling to the bottom. You will find more information on travel mix later on.

5. Which are the gases in AIR?

We have 20 % oxygen, 79 % Nitrogen and 1 % other gases.

6. What does partial pressure of Oxygen mean?

The partial pressure of a gas is the pressure of any gas at depth. The limits of oxygen toxicity at depth is of 1.6. That means that you cannot use Air at a greater depth than 66 meters. So if you are using 31% mix all you do to know the Maximum Operating Depth (MOD) is 1.6 divide by 0.32 = 5 - 1 = 4 BAR which is equal to 30 meters. Not difficult isn't it.

7. Is Nitrox used to do dives of 70m+ ?

No It is not ideal to do these type of dives. Nitrox is a mixture of higher partial pressure of oxgyen which reduces your maximum operating depth.

8. Isn't Nitrox "mixed gas" for comercial divers only?

Nitrox is not mixed gas. It is a blend of the same gas that you are breathing NOW. It is just enriched with a specified percentage of O₂

9. Why do I need to use Nitrox?

Every diver knows that nitrogen (N₂) causes narcosis at depths greater than 30 meters. It also enters the blood stream and is then absorbed by all body tissues. On ascent from depth this can cause decompression sickness if absorbed in high enough volume. With Nitrox there is less N2 and consequently less problems with nitrogen.

10. Doesn't more oxygen cause problems?

Training teaches you how to use the Oxygen Enriched Air with a very significant safety factor. Using Nitrox of the correct blend, at 45 meters is in fact, safer, than using air at 30 meters.

11. What new diving equipment do I need to dive using NITROX?

No new equipment is required if the oxygen content is not to exceed 40%. Nitrox is compatible with existing SCUBA equipment.

12. What is hydrocarbon free gas?

It is a air which is filtered to eliminate nearly all traces of oil in the AIR or mixture.

13. It is true that once a cylinder is filled with nitrox it can never be used with air again?

It should only be filled with hydrocarbon free gas. Nitrox does not affect the inside of the cylinder in any way. However a cylinder colour coded for Nitrox means that the gas inside is oxygen enriched air. Refilling with air would not be a safe practice unless the cylinder colour coding is removed.

14. I heared that nitrox is only safe to 40 meters ! What if I want to do deep diving?

When you take a course on nitrox, they will teach you how to select the optimum oxygen content for your dive depth.

15. Why would you want to use nitrox?

In short, the correct nitrox mix is safer than air for the divers.
