Gear - Although the gear is the same, divers who are enrolled in an introductory tech class (Intro Tech, Sidemount, or CCR Air Diluent) will notice fundamental differences in the configuration. Instead of having 2 second stages per cylinder, they are split into two with each stage having a separate first. The gas planning process becomes more detailed and the harnesses have more chrome.
With most agencies you can choose between recreational Sidemount and technical Sidemount. The prerequisites for example with SDI and TDI are the same but the tec Sidemount course will add more skills. It will also ask more of you in terms of mastering them perfect trim and keeping still and leveled during your skills is a must!
Divers using decompression oxygen mix all types can extend their time looking at wrecks or reefs on the oceanfloor. The sport diver may be limited to two short dives at 100ft. A decompression diver can cruise the seas for 60 minutes or longer, getting more bang for his buck.
In general Sidemount is more task loading for a diver as the pressure in each tank needs to be balanced in order to have enough gas for an out of air diver and to be balanced on each side.
Scuba sidemount diving is very popular, even in open sea.
I just arrived on Malapascua Island (Philippines) and will soon be working my path to becoming a Tec instructor. I've been working as a recreational instructor at Bali for the past two-years and would love to grow my professional experience. Sidemount PCB gave me my first taste in technical diving. Tom West was the PADI course director, and Tec instructor-trainer. He made me into a PADI Tec-50 diver.
Sidemount mounting for cylinders was originally used in cave diving. Since then, they have grown to be more popular in all types of technical diving. The dual cylinders are separated with a 1st stage for each cylinder. They then mount them on either one side of the diver's bodies. However, this does not allow the diver access to any valves and allows him to only breathe from one cylinder in the unlikely event of a regulator failing. Sidemount diving offers a divers a wider horizontal profile, but smaller vertical profile.
Take a look at these three options if diving classes and lessons are not what you desire or you need to decide where to go next.
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.
Interested in becoming a Sidemount diver? You have come to the right place as this post is all about the nitty-gritty of what is involved!
Sidemount diving is a great option, especially for those who are already tec divers. You will need to learn how to adjust your rig, how you can enter the water with it (yes, it is different, but it is more relaxed).
Be aware of what you're paying: All prices include instruction and eLearning. The cost of eLearning by itself can range from $140 to $280. A $640 course purchased from us may cost you the same as $500 from someone else, if you need to pay for elearning separately.
Mentality Technical diving is still fun. Its all about seeing cool things, just like sport diving, but technical divers see sights longer, deeper, and hidden to the sport diver. While technical divers are still fun-focused they also regular focused. Jokes can still be made, laughs can still be had, but a certain sense of serious must come about when it comes to dive planning and execution. All diving has risks, and those risks are increased if proper planning, skill practice, and execution are not done.
Next, it was time to do technical sidemount. This involves adding our deco 50-percent and 100-percent oxygen tanks on each side. You will have a higher profile underwater, so it is important to keep the tanks as close to your body as possible. There are two clips at each side of the waist. You adjust the tank position by inhaling down your tanks. This is where simplicity is key. You also need to switch between tanks every few minutes. This ensures that the pressure in each tank is at the same level, so even if one tank or regulator fails, there will still be gas for you to breathe. Building up experience is the key to comfort, enjoyment and success with new technologies. The next few days were spent doing sidemount dives, budding up with Evolution coowner David Joyce, a highly experienced Tec diver and Trimix instructor. One dive took us to the Japanese Mogami Wreck at 164 feet. I was captivated by the old gas masks, uniforms, and bones that we found.
from 170 to 350 feet
While conventional scuba diving has a recommended maximum depth of 130 feet, technical divers may work at depths ranging from 170 feet to 350 feet, and sometimes even deeper.
