Technical diving is a specialty type of diving that goes above and beyond recreational diving. It is usually conducted for non-professional purposes, and poses greater risks. These include higher risks of serious injury or death. Below are some tips to help you stay safe when tech diving. You can read on for more. We will also discuss closed-circuit equipment, TecRec. This will make it easy for you to get started.
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 to augmented and nitrogen. It also allows for higher mixed-gas ratios. 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. They use only one-third of each cylinder during exploration. They keep the unused gas cylinders safe until they can be used again. They also use a single main container, which requires two separate regulators. A diver can go up to half a mile into a cave using four stages.
Closed-circuit equipment
The term "technical diving" was coined in 1991 by Michael Menduno, and it describes a variety of practices and equipment configurations used to expand the range of human diving. In the beginning, technical diving was dominated by open-circuit designs. They were chosen for their flexibility, reliability, and availability. However, today, many scuba divers use closed-circuit equipment, which is becoming more popular.
Being flexible to new situations
Tech diving involves knowing the basics of decompression theory as well as gradient factors. While most teams stick with one decompression algorithm, an increasing segment of the tech community is moving towards dual-phase models. Understanding the parameters your chosen model uses to travel between waypoints is key. Also, know what you can do to adapt to unforeseen circumstances. Safety is dependent on tech diving being able to adapt to new situations.
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 divers use equipment that is similar to recreational divers but it's made for different purposes.
