Technical diving is a specialty type of diving that goes above and beyond recreational diving. Technical diving is often done for non-professional reasons and poses higher risks. These include greater risks of serious injury and death. Here are some safety tips for tech diving. You can read on for more. We'll also be discussing closed-circuit technology and 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 teaches the basics of tec-diving in confined water. If you pass the Discover Tec test first, it could count towards your Tec40 course. Not only will you receive the training, but you'll also be able to use some of your TEC gear and techniques.
PADI Tec 40
PADI Tec40 is the next logical step for divers wanting to expand their horizons into deeper dives. 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. 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 are able to dive into caves using open-circuit scuba. This is a unique adventure that pushes horizontal scuba's limits. These divers can travel thousands of feet into caves using open-circuit scuba, which has a separate regulator for each stage. During exploration, they use one-third of the gas in each cylinder. When they leave the cave, they secure the unused cylinder to be retrieved. They also use a single main container, which requires two separate regulators. A diver can travel up to half a kilometer into a cave by using four stages.
Closed-circuit equipment
Michael Menduno created the term "technical divers" in 1991. It is a collection of different practices and equipment combinations that expand human diving's range. Open-circuit equipment was the most common type of technical diving. These were chosen for their reliability, flexibility, and availability. Nowadays, however, the standard for many divers is closed-circuit equipment.
Adapting to new circumstances
Decompression theory and gradient factors are important to know when tech diving. While most teams stick with one decompression algorithm, an increasing segment of the tech community is moving towards 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
You need to be aware of the differences in gear configurations, whether you are diving for recreational or professional purposes. For one, technical divers need more equipment to solve problems at depth. These divers usually use multiple cylinders for gas, regulators as well as cutting and other tools. While these equipment may look similar to recreational diving, they are made for specific purposes.
