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. Here are some safety tips for tech diving. Keep reading for more information. We'll also be discussing closed-circuit technology and TecRec. Once you have read this, it's time to move on.
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. The training will be comprehensive and you will have the opportunity to learn some of the techniques and gear required to dive in TEC settings.
PADI Tec 40
The next step for divers looking to broaden their horizons and dive deeper is the PADI Tec40 course. This course teaches divers advanced techniques in augmented air, nitrogen, higher mixed gas ratios, and also includes enriched air, decompression diving with EANX 50. You will also be able to practice decompression software. The goal is to make it safe for divers to dive to 40 meters without risking decompression illness.
Cave diving
Tech divers can cave dive, which is a thrilling adventure beyond horizontal scuba diving. 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 one third of the gas in each tank. 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. You can dive up to half an mile in a cave with four stages.
Closed-circuit equipment
Michael Menduno coined the term "technical" diving in 1991. This term refers to a wide range of practices and equipment configurations designed to improve human diving. Most technical diving used open-circuit systems in the beginning. They were chosen because they were reliable, flexible, and easy to use. Closed-circuit equipment has grown in popularity and is now the standard for many scuba divers.
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 requires tech diving to allow you to adapt to changing situations.
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 these equipment may look similar to recreational diving, they are made for specific purposes.
