Technical diving refers to a particular type of diving which goes beyond recreational diving. It is usually conducted for non-professional purposes, and poses greater risks. These include greater risks of serious injury and death. Here are some tips to keep you safe when diving into tech. Keep reading for more information. We'll also cover closed-circuit devices and TecRec. You'll be ready for anything once you've finished reading it.
TecRec
You might consider registering for TecRec if you are already certified and wish to learn more about tech diving. This course teaches the basics of tec-diving in confined water. If you pass the Discover Tec test first, it could count towards your Tec40 course. In addition to the training you'll receive, you'll also get to use some of the gear and techniques that are necessary to dive in TEC configurations.
PADI Tec 40
PADI Tec40 is the next logical step for divers wanting to expand their horizons into deeper dives. This course teaches divers advanced techniques for augmented oxygen and nitrogen. It allows for higher mixed gases ratios and includes enriched and decompression dives on EANX-50. They will also have the chance to use decompression software. This is intended to allow divers to safely dive to 40m and beyond without getting decompression sickness.
Cave diving
Tech divers love cave diving. It is a challenging adventure that challenges the boundaries 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. They only use one-third to three percent of each cylinder for exploration. The unused cylinder is kept safe for them to retrieve when they leave the cave. They use one main cylinder that requires two 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. Open-circuit equipment was the most common type of technical diving. These were chosen for their reliability, flexibility, and availability. Today, however, closed-circuit equipment is increasingly popular and has become the standard for many scuba divers.
Ability to adapt to changing situations
Decompression theory and gradient factors are important to know when tech diving. Many teams still use the same decompression algorithm. But, a growing portion of tech professionals are switching to dual-phase models. It is important to know what your chosen model does when moving between waypoints, and how to adjust them if necessary. Tech diving requires you to be able adapt to new situations.
Gear configuration differences
Gear configurations are important, regardless of whether you're diving recreationally or for a career in technical diving. To solve depth problems, technical divers will need more equipment. Technical divers often use multiple cylinders, regulators, cutting instruments, and SMBs. These divers use equipment that is similar to recreational divers but it's made for different purposes.
