Technical diving is a specialty type of diving that goes above and beyond recreational diving. It is generally done for nonprofessional purposes and poses more risks. These include increased risks of death and serious injury. Below are some tips to help you stay safe when tech diving. Learn more. We will also discuss closed-circuit equipment, TecRec. Once you have read this, it's time to move on.
TecRec
You may be interested in a TecRec course if you're already certified and would like to learn more. This course teaches you basic tec diving techniques in confined and may count towards your Tec40 certification if passed the Discover Tec. Along with the training you will receive, you will also learn how to use certain gear and techniques to be able dive in TEC configurations.
PADI Tec 40
For those divers who want to expand their horizons to deeper dives, the PADI Tec 40 course is the next logical step. This course introduces divers to advanced techniques for augmented air and nitrogen, allows for higher mixed gas ratios, and includes enriched air and decompression diving on EANX 50. As part of the course, they are also given the opportunity to practice using decompression software, and is designed to help divers safely dive to 40 meters and more without risking decompression sickness.
Cave diving
Cave diving for tech divers is an adventure that pushes the limits of horizontal scuba. These divers can travel thousands upon thousands of feet into caves with open-circuit diving, which has a separate regulator to each stage. During exploration, they only use one third of the gas in each tank. When they leave the cave, they secure the unused cylinder to be retrieved. They also use a single main cylinder, which requires two independent regulators. You can dive up to half an mile in a cave with four stages.
Closed-circuit equipment
Michael Menduno invented the term technical diving in 1991. It describes a variety if practices and equipment configurations that can be used to enhance human diving. At first, technical diving used open circuit configurations. These were chosen for reliability, availability, and flexibility. However, today, many scuba divers use closed-circuit equipment, which is becoming more popular.
Ability to adapt to changing situations
Tech diving involves knowing the basics of decompression theory as well as gradient factors. Many teams still use the same decompression algorithm. But, a growing portion of tech professionals are switching to dual-phase models. The most important thing is to fully understand what parameters your chosen model assumes for traveling between waypoints. And how to modify these parameters if an unexpected circumstance arises. It is crucial to adapt to new situations when tech diving.
Gear configuration differences
Gear configurations can make a difference whether you dive for recreational reasons or to pursue a career as a technical diver. Technical divers require more equipment to solve depth problems. Divers in this category typically have multiple cylinders of gas, regulators and cutting tools. These equipment is very similar to what recreational divers use, but they are designed for different purposes.
