It turns out that nobody actually knows the real answer to this question. In fact, this question is the one most frequently asked of dive certification agency PADI. Renee Duncan of Divers Alert Network, a diving safety organization associated with Duke University, has said, "There's really no true number for certified divers because this is not a regulated industry, so it will always be a squishy figure. We've quoted the 1 to 3 million number on our diving fatality reports." Ben Davison, publisher of the dive industry journal "Undercurrent", researched this topic for a recent article. He puts the number of active divers (who make at least 5 dives per year) at 1.2 million, plus or minus 15%.

An important component of the "How many divers are there?" question is "How many new divers are certified each year?" In 2002, four dive certification agencies, PADI, SSI, NAUI and SDI reported certifying 177,000 new divers. These are the four largest training agencies in the world, but there are others as well. A good estimate for the total number of new divers trained worldwide is probably closer to 225,000. The annual attrition rate of these new divers is also widely debated, with estimates ranging from 50% to more than 80%.

How many feet can you scuba dive in?

That question doesn't have a simple answer, as there are a lot of variables you must consider, such as the diver's experience, genetic predisposition (affects whether or not the diver will experience gas toxicity or narcosis at a particular depth), and equipment (namely breathing gas composition and volume). Below are some rough guidelines...40ft (12m): Recreational diving limit for divers aged under 12 years old and beginner divers.60ft (18m): Recreational diving limit for divers with Open Water certification but without greater training and experience.100ft (30m): Recommended recreational diving limit for divers. Average depth at which nitrogen narcosis symptoms begin to appear in adults.130ft (40m): Absolute recreational diving limit for divers specified by Recreational Scuba Training Council.180ft (55m): Technical diving limit for "extended range" dives breathing air to a maximum ppO2 of 1.4 ATA.220ft (65m): Depth at which compressed air results in an unacceptable risk of oxygen toxicity.330ft (100m): Technical diving training limit for divers breathing trimix. Recommended technical diving limit.510ft (155m): Record depth for scuba dive on compressed air.1100ft (330m): World record for deepest dive on SCUBA.

How far down can a scuba diver go?

Recreational divers are certified by the recreational training agencies (PADI, NAUI, SSI, BSAC, etc) to depths as deep as 130 feet. Most recreational diving takes place above 100 feet and many regional dive operator organizations, including the Cayman Islands Watersports Association, officially limit dives to 100 feet. In fact, most recreational dives occur in relatively shallow depths of 60 feet or less, since most coral and sea life exists above those depths. Scuba diving, however, is not limited to recreational diving. Self Contained Underwater Breathing Apparatus (SCUBA) allows technical and commercial diving to depths well in excess of 130 feet. Humans reach a physiological limit of about 210 feet using normal air as a breathing gas. Below this depth, the oxygen in air reaches partial pressures that become toxic. For this reason, deeper dives are accomplished using mixed breathing gases that contain reduced perentages of oxygen. Deeper depths also increase the risk of decompression illness (also called the "bends"), caused by intert gases (primarily nitrogen) being absorbed by body tissues during prolonged exposure at elevated pressures. Ascending divers require "decompression stops" during ascent to allow time for these absorbed gases to escape from body tissues. It is to avoid these mandatory decompression stops that recreational divers are limited to 130 feet. With the right training, equipment and breathing gas, scuba dives have been made to great depths. The current record for an open circuit scuba dive is 318M (1042 feet). This dive required over 8 hours of decompression stops during the ascent.


Can you go on a recreational scuba dive without certification?

Yes. There is no law that prevents uncertified divers diving. However, most shops require some kind of training for liability reasons.However, many organisations (including PADI), offer "discover scuba diving" courses (sometimes referred to as "resort courses" because they are often done on holiday), which take just a half a day, and allow you to dive under the supervision of an instructor to limited depths.


How many people scuba dive?

Nobody knows exactly, but the estimate of 50 million is commonly used. Approximately 1,000,000 new divers are certified every year, but not all divers are certified. Nicaragua for example has over 50,000 lobster divers, very few of whom have formal training.


How much does an average scuba diver weigh?

I am a Scuba certified and I weigh 150 Lbs, in my class there were some other people in the 250+ range, and there were people as light as 90 Lbs. Basically what I am getting at is that as long as you can swim you can Scuba dive. Average weight is very hard to determine since there are so many various divers.

When should one not learn scuba dive?

most training agencies suggest that SCUBA be taught after 9years of age and should not be engaged in for one is a heavy smoker or has respiratory problems. Scuba is a high stress anaerobic activity. Anyone at risk of heart disease or arterial sclerosis should not participate. This is not medical advice. Please consult a doctor before engaging in SCUBA diving. also: if they don't want to.... too many divers start SCUBA diving to be with somebody they care for, (husband, girlfriend, etc) but have no desire to actually SCUBA dive.

The tropical island of Roatan is located just off the coast of Honduras in the western Caribbean. As the largest of the Bay Islands, this island paradise features world class scuba diving on the second largest coral reef in the world that is located just offshore. The clear Caribbean waters are the focus of activities on Roatan. Many island hotels cater to scuba divers, providing customized diving packages that include unlimited boat and shore diving. Non-divers will love the unspoiled beaches with plenty to do from horseback riding to snorkeling, sailing and fishing. A wide variety of hotel accommodations are available for every budget. Most resorts and lodgings are located on or just a short walk from magnificent white sand beaches. Many cruise ships stop in Roatan, providing another way to experience the island’s unspoiled beauty. One of the best kept secrets in the Caribbean, Roatan is the perfect vacation destination for everyone from scuba divers to sun worshipers.
