Technical diving refers to a particular type of diving which goes beyond recreational diving. Technical diving is often done for non-professional reasons and poses higher risks. These risks include serious injury and death, as well as increased risk of death. Here are some tips to keep you safe when diving into tech. You can read on for more. We will also discuss closed-circuit equipment, TecRec. Once you've read this, you'll be ready to go.
TecRec
If you're already certified in tech diving and want to learn more, you might be interested to take a TecRec training course. This course is designed to teach you the basics of tec diving in confined water, and it may even count towards your Tec 40 course if you pass the Discover Tec first. You'll be able to use the equipment and techniques necessary to dive in TEC configurations, along with the training.
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
Tech divers can go cave diving. It's an adventure that takes horizontal scuba to new heights. They can dive into caves up to a thousand feet using open-circuit Scuba. Each stage is controlled by a separate regulator. During exploration they only use about one-third the gas in each of their cylinders. 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. Four stages allow a diver to go half a mile deep into a cave.
Closed-circuit equipment
Michael Menduno in 1991 invented the term "technical dive". It refers to a range of techniques and equipment configurations that are used to increase human diving's capabilities. 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.
Adapting to new situations
Tech diving requires you to be familiar with gradient factors and decompression theory. Although most teams will stick to one decompression algorithm for their dives, some tech communities are moving to dual-phase models. The key is to understand the parameters that your chosen model assumes when traveling between waypoints and what to change if a contingency arises. Safety is dependent on tech diving being able to 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. For one, technical divers need more equipment to solve problems at depth. Technical divers often use multiple cylinders, regulators, cutting instruments, and SMBs. While the equipment used for these types of diving is similar to recreational divers', they're designed for different purposes.
