PSAI Narcosis Management® Levels 1, 2, 3, 4 & 5


PSAI Narcosis Management® is our signature course, with 50 years of continuous development and perfection behind it. This training, the best in the world, has divers perform only the underwater skills that relate to the actual real world of diving. Divers will be required to keep up with Depth, Air, Time and Awareness (DATA). Divers must become comfortable and competent with the mental and motor skills at each training depth before training down to the next level. PSAI is the only agency offering Narcosis Management® training down to 240 feet (73 meters). It is taught in seven different depth levels, allowing the diver choice of training depth. This Narcosis Management® course is taught on air, to better prepare divers for Trimix diving which requires the use of the less forgiving helium based gases. Good buoyancy control, gas management, gas switches and runtimes are best learned while diving on air. However, divers certified on other gas mixtures or rebreathers can also benefit from Narcosis Management® training.

PSAI Advanced Nitrox Diver


The PSAI Advanced Nitrox Diver Manual is written for those divers who training to utilize enriched air (Nitrox) at oxygen concentrations up to and including 100% by volume (EAN22 to Oxygen) in their diving activities, including stage decompression procedures.

PSAI Extended Range Nitrox Diver


The Professional Scuba Association International’s (PSAI) Extended Range Nitrox Diver course is designed for those divers who wish to conduct dives beyond 45 meters (150 feet) but not exceeding 55 meters (180 feet), using staged decompression techniques for both depth and extended bottom times. This course uses air as the primary back gas and nitrox(s) as decompression gas(es).

PSAI Trimix Programs: -Trimix Fundamentals Diver -Expedition Trimix Diver -Explorer Trimix Diver


The PSAI Trimix Diver courses are designed for those divers who wish to conduct dives using helium based bottom mixes with associated advanced staged decompression techniques. The PSAI Trimix Diver program is conducted in three phases leading to dive depths of up to 100 meters (330 feet).

PSAI Technical Emergency Analysis & Management: Team Program™


The Professional Scuba Association International’s Technical Emergency Analysis & Management (TEAM™) Diver course is designed for those divers who wish to learn the skills necessary to complete self-rescue and “buddy assistance” rescues in the technical diving environment.

PSAI Advanced Wreck: Penetration – Overhead Diver


The Professional Scuba Association International’s (PSAI) Advanced Wreck: Penetration-Overhead Diver course is designed for those divers who wish to penetrate wrecks using proper techniques. These penetrations are not simple swim-throughs, but rather multi-level or multi-turn dives. This course is NOT a “progressive penetration” memorization technique course. The dive team will always maintain a continuous guideline leading to the exit while in the wreck overhead environment, The diver(s) shall not dive deeper than they have been previously certified. The maximum depth of this course shall be limited to the previous air training depth of the candidate, or 55m (180 feet), whichever is shallower. For the training or any penetration dives, the maximum allowed Equivalent Narcosis Depth (END) is 40m (130 feet), if the candidate is certified to such depths.

TDI Intro. To Technical Diving


The TDI Intro to Tech Course is an introductory course that expands on recreational training by improving dive planning methods, in-water skills, and streamlining existing gear configurations in a controlled and fun learning environment.

TDI Advanced Nitrox Diver


Are you looking to expand your dive time? Maybe you’re a scientific diver or photographer looking to stay in the water a little longer?The TDI Advanced Nitrox Course qualifies divers to use enriched air nitrox from EAN 21 through EAN 100 percent within your current certification level to a maximum depth of 40 metres/130 feet during dives that do not require staged decompression. Often taught in conjunction with the TDI Decompression Procedures course, this can be considered the foundation of your technical diving career. TDI Advanced Nitrox is also a must for SCR or CCR divers.

TDI Decompression Procedures Diver


Are you finding your no- decompression limits (NDLs) a limiting factor to dives? Do you have to ascend sooner than you would like? As sport divers, planned decompression is not something that we do or have been taught.The TDI Decompression Procedures Course prepares you for planned staged decompression diving. With a maximum operating depth of 45 metres/150 feet, this course is your first step beyond the normal sport diving limits. The TDI Decompression Procedures Course combined with the TDI Advanced Nitrox course form the foundation of all other technical courses. After these two courses and some additional experience, the stage has been set for you to move onto additional technical levels.

TDI Extended Range Diver


Certain areas of the world provide spectacular dives at depths deeper than 39 metres/130 feet but you may not have access (or very limited access) to helium. The TDI Extended Range course teaches you the proper techniques for utilizing compressed air as a breathing gas, and with a maximum depth of 55 metres/180 feet, so you don’t have to miss those dives! The TDI Extended Range Diver Course provides the training and experience necessary including proper techniques, equipment requirements, and hazards of deep air diving, to competently utilize air for dives up to 55 metres/180 feet that require staged decompression, using nitrox mixtures or oxygen during decompression.

TDI Sidemount Diving

The new SDI/TDI Sidemount Diver program is far more than just another “how to” on sidemount diving. It’s a complete, comprehensive training program designed to make learning sidemount diving easy and fun. On top of this, all of this information is available as an SDI/TDI eLearning course that covers the same material, in the same sequence, and in the same depth.

TDI Advanced Wreck Diver


The TDI Advanced Wreck Diver Course is the next step for any diver that has successfully completed the SDI Wreck Diver Course. During this course, your TDI Instructor will teach you the proper techniques for locating and planning an advanced penetration dive. The advanced wreck course is commonly taught with other popular TDI courses such as Advanced Nitrox, Decompression Procedures, Extended Range, Closed Circuit Rebreather, and Trimix.
