However it is important at greater depths to decrease effort and achieve maximum performance to avoid overexertion and CO2 buildup. CO2 is the trigger for our breathing reflex, so the more CO2 we build up the more we will feel the urge to breathe. This means in the same amount of time we will pump more gas through our lungs and we take in more gas in the same amount of time.

Sidemount rigs were originally designed for cave diving. They allow the diver to easily pass through cracks and restrictions (tiny holes), much faster than traditional back mount rigs.

Sidemount provides many benefits for divers but is best suited to cave diving. Sidemount was in fact invented by cave divers. These are just some of the benefits.
Decompression divers can dive to depths of 130ft. They can add Helium to their cylinders, and then they will be able to explore the world of the rare. They often visit the wrecks and reefs less often than astronauts to Mars every year.
The goal of this course is to teach you the basics of how to use the equipment in your cave or tech diver training. You will also need the same equipment for the course. This includes:
Since the beginning of the century, one of the most significant changes in the equipment cave divers use has been the shift from backmounted doubles to sidemount. Not only do a substantial number of cave divers now sidemount, it’s possible that there are more open-circuit sidemount cave divers than backmount cave divers.
Do not worry about how it all will come together. A large part of the course teaches you how to set up Sidemount equipment and how to adjust bungees to ensure your tanks are in good shape. Your instructor will be there to help you through it all!
The initial pool sessions were tough; I felt like an open-water diver again, strapped into the twin tanks and trying to conduct valve drills. But as we progressed through the Tec 40, 45 and 50 courses, new skills started to come naturally, and by the end of the course I was enjoying myself. The satisfaction in Tec diving comes from taking your dive skills, buoyancy and awareness to the next level. Knowing that you’re capable of managing life-threatening emergencies at depth, and without the option to ascend straight to the surface (due to decompression requirements) is quite a buzz. And it’s satisfying to execute your dive plan with military precision.
To get started on Sidemount diving you don’t need more than an Open Water Diver. Mind you, it obviously helps to have good buoyancy and trim and you should be able to set up and handle your equipment comfortably by yourself. Sidemount diving will add a whole new dimension when it comes to equipment setup and skills.
Some other wreck diving books are ‘The Last Dive’ by Bernie Chowdhury about father and son who are crazy about wrecks and eventually find their destiny on a German U-boat.
Computer-aided instruction is an integral aspect of almost all courses we teach. The Why? The simple answer is that eLearning allows students to get in the water faster and spend more time there. This is why we include any applicable eLearning program -- typically a $140 value -- in all our courses at no extra cost. This is equivalent to an additional day's in-water training. This is what it's worth. Priceless.
According to experts, approximately 40% of technical divers enroll in additional education and training programs. This yields a reasonable estimate of approximately 160,000 active technical divers worldwide.
5-6 days
Rebreather training classes are typically 5-6 days long, but can be longer depending on a variety of factors such as the training agency, your local conditions, your instructor, and your ability to meet the class standards.
Have a PADI Deep Specialty Instructor certification or have completed a PADI Deep Specialty Instructor course. Have at least 100 logged dives, including at least 20 enriched air dives, 25 dives deeper than 18 meters/60 feet, and 15 dives deeper than 30 meters/100 feet. You can become a Tec 45 diver.
