Essentials of Technical Diving class is the first step to move you from ‘Recreational’ diver to ‘Technical’ Diver. Essentials of Tech gives you all the personal skills you need to move to a training program that increases both depth and time in the water.
Essentials of Tech takes place in 20-30’ / 6-10m of open water. It is a personal skills class that prepares you for technical depths by advancing your control of buoyancy, trim, and propulsion, while introducing you to more advanced air sharing procedures and deco bottle handling protocols. The class also introduces you to more advanced gas planning and more complicated ascent strategies.
Essentials of Tech acts as a bridge between conventional training and more demanding technical curriculum and focuses on training you to become a “Thinking Diver,” regardless of whether you are going to move forward with technical training, or are just looking to become a more highly skilled recreational diver.
Minimum 18 years of age
Rec 2 or equivalent
Minimum of 50 dives beyond open water certification. 25 of which must be non-training dives
Maximum depth is 60’/18m
Standard gas is Nitrox 32
No stage decompression .
Who this class is designed for? Many divers find all the adventure they need in recreational dives to 100′ or less. But some feel that maybe they are missing some skills that technical divers have such as “horizontal decompression stops”. Or maybe you linger at the top of the wall, looking down into the inky abyss? Does the idea of penetrating a wreck, with only your lights and a guideline to lead you give you good goose bumps? Do you think you’ll never be happy unless you’re flying past a pinnacle at 200′ on a scooter? Technical diving is about having fun, just like any other pastime. But, like anything worth doing, it requires perseverance and hard work. This class is designed for the diver eager to learn some basic technical diving skills which can help improve their recreational diving ability or want to begin building a strong foundation to start pursuing the challenge of technical diving.
Why Take this Class?
Maybe you want to learn something new or you want to improve your safety by learning to do horizontal air sharing drills. Regardless of your motivation, in this class you will be introduced to the technical diver’s toolbox. You will learn to hover motionless, move forward and backward, turn around without disturbing the bottom. You will learn to air share gas with your teammate in a reasonable and efficient manner. You will learn to ascend, making appropriate stops while deploying a surface marker to alert the boat and support team of our predicament to basic use of a deco bottle. In the classroom, technical divers need to know which gas to choose and why, how to plan a dive (including Decompression techniques), from the back of the truck to a bench on the boat, and how to ensure that everyone has a great time and gets home safely. Essentials of Tech isn’t about showcasing the latest equipment, or rushing you into the next class. It’s about working to develop skills that will improve your dive, and thus propel into a world of exploration.
The Essentials of Tech class is designed to be taught over a three full day period, with eight hours of class and four open water dives.
Day 1. Typically the class begins with a 3 – 4 hour initial session consisting of introductions, a power point presentation including video tape of the skills to be evaluated throughout the class. Following a break for lunch and then a 3-4 hour of hands-on equipment fitting, review of gear configuration and a discussion of the pro’s and con’s of various equipment choices. Once the gear in properly fitted and configured the class then focuses on the “dry runs” of the skills and some practice before entering the water. Dry runs allow the student to practice the skills on land, before entering the water, under the watchful eye of the instructor(s). Skills include evaluation of divers trim, proficiency and precision buoyancy control, perfecting propulsion techniques (including learning how to kick backwards), fine-tuning equipment configurations, refining underwater communication, utilizing a team diving approach, and effective dive planning
Day 2. Begins with students conducting two dives, putting the skills and concepts discussed the previous day into practical use while the instructor demonstrates and the videographer captures the in-water session for review and evaluation after lunch. We conclude the day with a 1-2 hour video review where the performance is analyzed, with long discussions on how to improve. Finally, 2-3 hours of lecture brings the day to a close.
