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.
On top of this specialized Sidemount equipment, you will also need your usual wetsuit, fins, mask, computer, compass, and DSMB.
Continue on to the Tec Sidemount Diver program. Here you'll learn additional skills, such switching deco cylinders, and stage and switch deco cylinders.
I'm not sure when or why I chose to take my Sidemount course. It was, as with many of my diving decisions. I think it was a case where I thought, "Oh, that looks cool. Could be useful. I'm going for it!" I knew Sidemount would be useful and something I could continue to use and improve on. Sidemount certification would be useful for me if I ever wanted to cave dive.
SDI/TDIIncludes two open water divesMinimum of 18 years, or 15 with parental consent
Technical diving is a combination of passion, training, and experience. Technical diving is not for those who lack any of these three.
Your Sidemount BCD is a harness with a bladder and a somewhat intricate system of sliding D-rings, bungee cords, and clips. Their position and fit are crucial for your tank position and trim later in the water and your instructor will probably spend quite a bit of time to get them just right.
You can share the adventure or give the gift that never ends! PADI eLearning(r), which you can purchase and send to any recipient of your choosing, is now available! It doesn't matter if you want to give the course as a gift, or if you need to assign it to your family members.
In addition, your Sidemount rig includes tank bands, clips, and probably some more bungees to stow away your regs nicely. The clips will be connected to your harness and again, their position is important for the position of your tanks.
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.
We offer the TDI course as an option, although we can also teach the SDI course if asked. This course can be taken on its own, or with the Apprentice Cave Diver course.
The SSI technical-sidemount diver course allows you to take extended dives with four+ tanks (cylinders). Technical diving is easy with the technical sidemount course. You can learn to operate multiple cylinders at once. Config your sidemount gear. Learn how to make a tec sidemount harness. Also learn how adjust the sling tanks on your body.
Gear - While the gear remains the same, divers taking an introductory tech class, such as Sidemount, Intro to Tech or CCR air diluent, will notice some configuration differences. Instead of two second stages on one cylindrical, they're divided between two with a separate initial stage for each. The gas planning becomes a more in-depth process, and the harnesses appear to have more chrome.
PADI Training is available for both Android(tm), and Apple(r), iOS devices. Devices should not be older than three years old and have the latest OS (operating systems).
2-3 hours
Even with small cylinders, you can usually dive for 2-3 hours (rebreathers typically have two 2/3l cylinders or one 3/5l cylinder).
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.
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.
