Technical diving is a combination of passion, training, and experience. Technical diving is not for those who lack any of these three.
My first pool sessions were difficult. I felt like an open-water diver once more, strapped into twin tanks and trying valve drills. The Tec 40 and 45 courses were difficult at first, but I soon found that new skills became natural and I enjoyed the course. The joy of Tec diving lies in taking your diving skills, buoyancy, and awareness to the next level. The feeling of knowing that you are capable of handling life-threatening situations at depth and without needing to descend to the surface (dues to decompression requirements) can be quite satisfying. It's satisfying to execute your dive plans with military precision.
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!
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.
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.
Gear - While all gear is identical, divers in their introductory tech classes (Intro To Tech, Sidemount and CCR Air diluent), will notice some fundamental differences in their configurations. Instead of being split into 2 stages on a single cylinder, the second stages are divided up between two with a separate stage on each. Gas planning becomes more complex and the harnesses are more chrome.
Our Scotty's headquarters facility for diving, Scotty's Scotty's, is located in Mactan, Cebu. We offer Tec diving lessons (open-circuit or closed-circuit rebreather) as well as technical scuba diving classes. You can walk in if you're not a Shangri-la guest or we can pick your up at your hotel.
Sidemount diving is a great way to get additional air. There are two tanks that you use, one tank with an SPG and the other with regulators. This makes it safer and gives air-hogs like me a lot more air. Sidemount also makes diving extremely easy, since you can simply put tanks on top and there isn't any pressure on your spine.
Three parts are required to become certified: knowledge development, skill practise and open water diving. You can choose to do each part locally, on holiday or alternate between them.
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.
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.
