At first, technical diving was not something that interested me. I can clearly recall chuckling to my self at the Tec divers I observed, and wondering why anyone would want to have more equipment under water. I love the feeling of freedom and closeness to nature that can envelope you in "the quiet world". Tom was a respected teacher who I felt it was important to share my experience in Tec courses with.
Academics – The academic portions of a technical course are very similar to any other scuba class. Students will do some self study and bring the new knowledge to a discussion with their instructor. The dive planning aspects for a technical course are significantly extended from what most individuals are used to but a vital part of executing a successful dive. In overhead and decompression diving, the gas management portions of the planning discussion will take longer than most divers are used to. They even utilize a computer program to calculate their gas volumes and reserves required for the dive.
A great fact book about technical diving is ‘Deco for Divers – A Guide to Decompression Theory and Physiology’ written by Mark Powell.
Your Sidemount BCD is a harness equipped with a bladder. It also has a system of sliding Drings, bungee chords, clips, and other intricate features. The fit and position of your tank are critical for how your tank looks and is trimmed later in the water. Your instructor might spend quite a while to make sure you have them exactly right.
You don't need to worry about how all this will work. The course includes learning how to set-up your Sidemount equipment, as well as how to measure and adjust clips and bungees so that your tanks are in perfect trim. You will have your instructor to assist you in all aspects.
New gear means new techniques. Scuba diving sidemount is easy if you have the right skills.
‘Caverns Measureless to Men’ by Sheck Exley, one of the pioneers of cave diving in Florida, USA. He also wore ‘Basic Cave Diving: A Blueprint for Survival’ which studies many cave diving accidents.
Sidemount diving was originally developed in cave diving. However, it has now made its way into recreational non-overhead diving. Simply put, sidemount diving means that you no longer wear one or two tanks on your back. Instead, you wear your tanks on either your side. The tanks can be attached to a Sidemount BCD with clips and/orbungee cords. This gives you great flexibility. Cave divers were able to use this flexibility to allow them to transport their tanks underwater and fit into tight spaces.
Sidemount diving is a great way to get additional air. There are two tanks that you use, one tank with an SPG and the other with regulators. This makes it safer and gives air-hogs like me a lot more air. Sidemount also makes diving extremely easy, since you can simply put tanks on top and there isn't any pressure on your spine.
For items such as primary and cylinder lights that may prove difficult to transport, rental is possible. We will be happy to assist you if you have any questions.
New gear means new techniques. Sidemount diving, even if it's simple, requires some new skills (easily learned).
These cards are only issued to those who have earned them. Participating in a course is not a guarantee of certification. Certification cards may be offered by multiple agencies for cave courses. C-cards cost $30 to $30 per card, depending on the agency. Ask your instructor for more information.
Technical divers can explore wrecks and reefs down to depths of 40 meters/130 feet. They can dive in underwater caves or other areas that are not accessible to recreational divers.
Sidemount regulators are also covered. You'll usually find one regulator on long hoses and one on shorter hoses with a necklace. Sidemount regs can be marked to distinguish the tank from which you are inhaling, unlike regular regs. This was a swivel-joint that I used to control my short hose regulator during my training. Additionally, you will receive two SPGs for each stage.
To register for the PADI Advanced Rebreather Diver course, you must first: You must be a PADI Open Water Diver, but you must also be a PADI Advanced Open Water Diver to become a PADI Advanced Rebreather Diver. Have at least 30 dives under your belt.
Technical diving (also known as tec diving or tech diving) is non-professional scuba diving that exceeds the agency-specified limits of recreational diving.
To begin a technical diving course, you must have completed the following prerequisites: a PADI Advanced Open Water Diver certificate or equivalent, a PADI Enriched Air Diver certificate or equivalent, and a PADI Deep Diver certificate or proof of at least 10 dives to 30 metres/100 feet.
