There are many great readings about technical diving. Some are stories of personal experiences and adventures in technical diving that are definitely worth reading. Some of the greatest books for sure are:
Scuba diving requires a minimum level of health and fitness. Chronic health conditions, certain medications and/or recent surgery may require you to get written approval from a physician before diving.
Sidemount regulators will be taught. Asidemount regulators can be used on both long and short hoses. Sidemount regs are marked differently to normal regs. This allows you to easily identify the tank that you are currently breathing from. In my training, I was given a swivel elbow to use as a regulator for my short tube. There will be 2 SPGs available - one each for each stage.
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:
Each PADI Specialty you complete gets you one step closer to earning the elite Master Scuba Diver™ rating.
Skills (general): The introductory tech diver will practice the use of new equipment to trim and control buoyancy. This helps to build the foundation for efficient diving. Once you have a solid foundation, you can start practicing locomotion or move on to more advanced skills.
Specific skills - The tech programs teach specific dive skills that are required for each category of diving. Navigation and line skills for overhead diving are practiced until they become automatic. Without blinking an eye, decompression divers are able to plan and execute gas management stops and stops. To ensure the equipment's perfect functionality, rebreather divers carefully build, test, and disassemble their equipment. Each course is covered in the initial level of certification. From there, you can move up to the next level. Each level of certification takes these skills deeper and makes them more challenging. This helps divers become well-rounded, knowledgeable and well-prepared.
Your Sidemount BCD harness is made up of a bladder, sliding D-rings and bungee cords. Your tank position and trim will depend on their fit. Your instructor may spend a lot of time getting them right.
Backmounted doubles were created in response to problems with single orifice and backmounted independences. Independents consist of two cylinders, each with its own regulator. The diver could only use one cylinder if a first stage failed. Single orifice duals consisted of two cylinders linked by a valve. One regulator was used for the first stage. The gas would not be released if the first stage failed due to a failure of one orifice doubles. Both of these problems have been eliminated by today's isolated manifold duplicates. Each cylinder is capable of being worked separately, but the diver can use one regulator to allow him or her to inhale gas directly from both cylinders. This type of doubles is usually held together using metal bands. Additionally, the valves are linked by an isolation manifold which allows the two to be separated as needed. Backmounted doubles diving looks similar to regular single cylinder backmounts, but it has a profile that is vertically identical.
If you're a Tec diver and want to do sidemount diving, it's important to know how to set up your new rig, adjust it, enter the water with it, and much more.
Cave passage formed over millions of years of water erosion that stretch thousands of feet from the entrance are reserved for those trained in overhead diving. The unique beauty and tranquility that these sites offer is only surpassed by the incredible timescale with which they formed.
Initially I had no interest in technical diving. I distinctly remember chuckling to myself at the Tec divers I saw, wondering why anyone would want to carry more equipment underwater. I love the sense of freedom and proximity to nature that can envelop you in “the silent world.” However, Tom had a reputation as an inspirational teacher, and as I was working in a dive shop with Tec courses it seemed rude not to at least try.
And then there are the rebreathers…a rebreather is a machine that recycles exhaled gas and is the preferred method for ‘very’ deep dives in order to use the gas carried more efficiently. In this case the exhaled gas is going thru a canister filled with a chemical which is called Sofnolime or scrubber to remove CO2 from the breathing loop and the remaining gas will be inhaled again by the diver. Metabolised oxygen is replaced into the loop to keep the oxygen content in the divers’ body at the desired pressure.
Television, magazines or stories from a close friend can all be used to explore the underwater world. It doesn't really matter which source you use, it is still exciting and very enticing. So what can we do to continue exploring? What is technical diving?
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.
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.
The depth range of oxygen rebreathers (simple closed circuit) is limited to approximately 6 m, beyond which the risk of acute oxygen toxicity rises to unacceptable levels very quickly.
