Technical diving is a specialty type of diving that goes above and beyond recreational diving. This type of diving is typically done for non-professional use and presents greater risks. These include increased risks of death and serious injury. These are some tips that will help you stay safe while tech diving. You can read on for more. We'll also be discussing closed-circuit technology and TecRec. After reading this, you will be ready to go.
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
PADI Tec 40 is the next logical step for divers who wish to explore 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
Tech divers can cave dive, which is a thrilling adventure beyond horizontal scuba diving. 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. A single main cylinder is used, which requires two independent regulators. A diver can travel up to half a kilometer into a cave by using four stages.
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. In the beginning, most technical diving efforts used open-circuit configurations, which were selected for their availability, reliability, and flexibility. Open-circuit equipment is becoming increasingly popular, and is the preferred choice for many scuba divers.
Adapting to new circumstances
Decompression theory and gradient factors are important to know when tech diving. Although most teams will stick to one decompression algorithm for their dives, some tech communities are moving to 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. It is crucial to adapt to new situations when tech diving.
Gear configuration differences
You need to be aware of the differences in gear configurations, whether you are diving for recreational or professional purposes. One reason is that technical divers need more equipment to solve deep diving problems. 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.
