Sidemount diving has many advantages. You have two tanks with one regulator, a first stage, and SPG. It makes it safer and allows for little air-hogs such as myself to get more air. Sidemount is also very comfortable, as you can quickly put tanks on the water surface and there's no pressure on your back.
The next day, technical sidemount was underway. This meant adding our deco 50 percent oxygen and 100% oxygen tanks on either end. The tanks will make you appear more prominent underwater. Each side of your waist has a few clips. As your tanks become buoyant from the air you exhale, adjust your tank to the second clip. You want to make your life as simple as possible. In a matter of minutes, your breathing is switched between the tanks. You can breathe easily because the pressure in each tanks is equal. Like all new things, experience is crucial to comfort and enjoyment. The following days I spent deco diving with the sidemount rig. My buddy David Joyce, Evolution co-owner and Trimix instructor, was with me. We went to the Japanese Mogami Japanese Mogami shipwreck at 164 feet. There, I was charmed and enthralled by the remnants of gas masks, uniforms, bones, and other old items we saw.
Sidemount regulators will also be covered. You will usually have one regulator for a long hose and one for a shorter hose with a necklace. Sidemount regs are marked, so that you can identify which tank you are using. This included a swivel joint to allow me to regulate my short hose. You will also receive 2 SPGs, one for each stage.
Certification cards: We issue these only when earned. Simply taking part in a course does not guarantee certification. For cave courses, certification cards from multiple training agencies may be available. C-cards generally cost around $30 each, depending on agency. Your instructor can tell you more.
If you worry now about how this will all come together, don’t – a big part of the course is learning how to set up your Sidemount equipment as well as to measure and adjust bungees and clips to make sure your tanks are in trim next to your legs. And of course, your instructor will help you with all of it!
Don't worry if you are worried about how everything will fit together. You will learn how to set up your Sidemount equipment. Also, how to measure and adjust your bungees and clips so your tanks stay in line next to your legs. Your instructor will guide you through all this!
Sidemount divers generally use two tanks. But you can use one tank, (I was told it's called monkey), or two tanks for deco dives.
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.
Gear - Although the gear is the same, divers who are enrolled in an introductory tech class (Intro Tech, Sidemount, or CCR Air Diluent) will notice fundamental differences in the configuration. Instead of having 2 second stages per cylinder, they are split into two with each stage having a separate first. The gas planning process becomes more detailed and the harnesses have more chrome.
It is possible to rent items such as primary light bulbs and cylinders which can be cumbersome to carry. You should let us know if any of these are required.
Sidemount provides many benefits for divers but is best suited to cave diving. Sidemount was in fact invented by cave divers. These are just some of the benefits.
Since the beginning of the century, one of the most significant changes in the equipment cave divers use has been the shift from backmounted doubles to sidemount. Not only do a substantial number of cave divers now sidemount, it’s possible that there are more open-circuit sidemount cave divers than backmount cave divers.
Sidemount BCDs are a harness that has a bladder and an intricate system of sliding D rings, bungee cables, and clips. They are important for the tank position and trimming later in the water. Your instructor will likely spend quite some time making sure they fit perfectly.
Skills (generally applicable) - The introductory tech dive will practice their buoyancy and trim with the new equipment configuration. This will help you to dive efficiently. Once this foundation has been established, students can practice locomotion to improve their skills.
According to experts, approximately 40% of technical divers enroll in additional education and training programs. This yields a reasonable estimate of approximately 160,000 active technical divers worldwide.
