Are you looking to expand your depth range? Do you want to reduce narcosis during deep dives? The TDI Trimix Diver Course could be your next step! As your motivation to explore progresses, you will find that you may want to go deeper to dive that wreck that is part of history or that cave system that you have read so much about. One of the major limiting factors of going deeper is narcosis; TDI’s Trimix Diver course shows how to minimize the effects of narcosis by adding helium to offset the nitrogen in your breathing gas. While taking the Trimix Diver course your TDI Instructor will teach you how to plan and execute dives utilizing as little as 18 percent oxygen and diving to maximum depth of 60 metres/200 feet with a blend of helium appropriate for the planned depth.

Having scuba tanks on your back isn’t a requirement for exploring the underwater world. Many scuba divers have discovered the joy of mounting cylinders on their sides. Sidemount diving gives you flexibility and streamlining options. Plus, you don’t have to walk with heavy cylinders on your back – just enter the water, clip them on and go. Sound interesting? Sign up for the Sidemount Diver Specialty course.
If you’re an Open Water Diver who is at least 15 years old, you can enroll in a Sidemount Diver course.
The TDI Sidemount Diver Course is the ideal specialty for any diver wishing to use this increasingly popular equipment configuration; either as a stand-alone course OR in conjunction with one of TDI’s other open circuit technical specialties such as Decompression Procedures, Extended Range, Trimix, Advanced Trimix, and Advanced Wreck. If this course is combined, the requirements for BOTH courses must be met. The TDI Sidemount Diver course teaches students how to utilize side-mounted primary cylinders as an alternative to the traditional back-mounted method.

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.
