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.
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.
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 also has clips and tanks bands. The clips will be attached to your harness. Once again, their positions are important for the location of your tanks.
Take our SSI technical sidemount dive course to learn how to use four tanks (cylinders) for longer dives. Technical sidemount diving is a great way to learn technical diving. It will teach you how to use multiple cylinders in one dive. You will also learn how to set up your sidemount gear, configuring a sidemount harness and how to adjust the sling tanks (cylinders).
Technical diving is defined by being exposed at the ceiling, which prohibits the diver from reaching the surface at any time during the dive. This can be due either to a literal ceiling (a cave, wreck, or virtual ceiling) or a decompression obligation. In such cases, mandatory decompression stops are required on ascent for anyone who exceeds the NDL. This may require the use of special equipment (e.g. Twinsets, Sidemount, special gas mixtures, and more training are needed to perform those stops as well as other tasks on ascent. This will optimize Nitrogen offgassing.
Cave passage formed over millions of years of water erosion that stretch thousands of feet from the entrance are reserved for those trained in overhead diving. The unique beauty and tranquility that these sites offer is only surpassed by the incredible timescale with which they formed.
Sidemount PCB is available to help you and your physician with questions about medical fitness for diving.
Mentality: Technical diving is still fun. It's just as much about seeing cool objects, like sport diving. However, technical divers see sights that are longer, deeper, or hidden from sport divers. Technical divers are still a fun and focused group, but they also stay on the right track. There are still plenty of jokes, and there are many laughs. However, dive planning must be executed with seriousness. You are always at risk when you dive, even if you have the right skills and practice.
Continue on to the Tec Sidemount Diver program. Here you'll learn additional skills, such switching deco cylinders, and stage and switch deco cylinders.
‘Shadow Divers’ by Robert Kurson is about the identification of a German submarine that was tried to be identified by John Chatterton and his crew during almost a decade.
The depth range of oxygen rebreathers (simple closed circuit) is limited to approximately 6 m, beyond which the risk of acute oxygen toxicity rises to unacceptable levels very quickly.
Have a PADI Deep Specialty Instructor certification or have completed a PADI Deep Specialty Instructor course. Have at least 100 logged dives, including at least 20 enriched air dives, 25 dives deeper than 18 meters/60 feet, and 15 dives deeper than 30 meters/100 feet. You can become a Tec 45 diver.
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.
