- What is PADI?
- PADI is The Professional Association of Diving Instructors. PADI is the world's largest and most widely recognized recreational scuba diver training agency. As a PADI diver you will have earned the finest and most respected diver credentials available.
- What is SDI and TDI?
- SDI is Scuba Diving International. SDI is the sport diver training agency of Technical Diving International together forming the worlds largest complete diver agency, able to train a diver from open water certification to any of a number of more advanced technical diver disciplines such as nitrox, wreck, timix and cave diver.
- What is the NACD?
- NACDis National Association for Cave Diving. The NACD is one of the worlds oldest cave diving training agency. The NACD is a non-profit organization run totaly by dedicated volunteers who donate their time and talents to the promotion of safe cave diving through education, conservation, service and exploration.
- What is Project A.W.A.R.E.?
- What is Confined water Training?
- Confined water training or diving is basic skill development sessions conducted in a pool or body of water having pool like conditions.
- What is a BCD?
- Buoyancy Control Device is the vest worn by divers used to adjust their buoyancy allowing them to float on the surface or when underwater like an astronaut experiencing zero gravity. The BCD also supports the air cylinder and regulator plus any extra equipment the diver may carry.
- What is a SPG?
- The Submersible Pressure Gauge or SPG is an instrument used by a diver to register the amount of air a diver has remaining in his air cylinder during the course of a dive. The SPG measures air in PSI-pounds per square inch much the same way a fuel gauge measures fuel in a car in gallons.
- What is a Regulator?
- The equipment used that permits the diver to breath the air from the air cylinder. The regulator also provides the connection of the SPG and the BCD to the air cylinder. The quality and performance of a regulator is measured by how easy it breathes.
- What is an Open Water Dive?
- A scuba dive made outside away from the confined water dive site or pool. Usually a student's first scuba dive in the ocean on a tropical reef.
- Explain what a Master Scuba Diver Trainer is?
- A Master Scuba Diver Trainer is a scuba instructor who may instruct beyond the basic open water level. Usually with the ability to instruct several different diver specialties of interests.
- What is the difference between Technical and Recreational diving?
- Recreational Diving is scuba diving which permits the diver to directly ascend to the surface, and is simple in the dive plan and logistics of the dive. Dives are no deeper than 130 feet. Technical diving is diving that requires training beyond recreational levels and requires more in depth dive planning and logistics. Technical diving is usually associated with overhead environments such as caves, shipwrecks and ice diving. Technical divers breath enriched air mixtures and will dive deeper than the 130-foot maximum recreational limit, thus requiring decompression ascents.
- Adventure Dives?
- Is a Divemaster Certification higher than an Instructor?
- No, The basic Open Water Scuba Instructor is a higher diver certification than a Divemaster.
- What is a Dive Profile?
- The dive profile is the overall dive plan to which a diver follows. It basically includes the diver's planned depth, air consumption, bottom time and any stops the diver makes during the ascent to the surface.
- What does NDL mean?
- NDL stands for no decompression limit and is the maximum amount of bottom time a recreational diver may stay down at a preplanned depth before the diver must ascend to avoid a decompression dive profile. Recreational divers follow NDL limits by use of a dive computer or dive planning table and bottom timing device such as a watch.
- What is Decompression Illness?
- Decompression Illness is also called the "BENDS". A condition caused by trapped surplus nitrogen bubbles in the body tissue thus producing a potentially harmful medical condition.
- What is Deco Diving?
- Deco Diving is Decompression Diving. This is a type of diving carried out by commercial, military and technical divers. When divers plan to exceed the set bottom time no decompression limits based on their planned depth, they plan for a series of ascent stops called staged stops or staged points, usually of 10 foot increments starting with the deepest stage point first. At these staged points they will remain for a predetermined amount of time with the intent to reduce the surplus nitrogen buildup in the body tissue preventing decompression illness.
- Who or What is DAN?
- Dan is Divers Alert Network. A non-profit organization dedicated to the safety of divers, through research and education. They are located at Dukes University, N.C. USA.
- What is a Scuba Unit?
- A scuba unit is a complete set up of the following components required by a scuba diver- A Buoyancy Control Device, a regulator with a SPG, depth gauge, compass, a primary and an alternate air source and a air cylinder. It may or may not include an integrated weight system.
