The next day was technical sidemount. This means that we added our deco 50 and 100 percent oxygen tanks on either side. This can increase your profile underwater. It is important that you keep your tanks as small as possible. The clips can be found on each side. As your tanks become buoyant, you will adjust your tank position to fit the second clip. Here, the goal is to be as efficient as possible. Each few minutes, you switch your breathing between the tanks. By doing this, the pressure in each of the tanks will decrease at roughly the exact same rate. In the event that a tank or regulator fails you will still be able to breathe. It is important to gain experience with any new thing. I spent the next few nights doing deco dives with the sidemount rig. I was buddied with Evolution coowner David Joyce who is a very experienced Tec diver as well as a Trimix instructor. One dive saw us visit the Japanese Mogami Japanese Mogami sank at 164 feet. It was here that I was seduced by old gas masks and uniforms as well as a few bones.
Continue on to the Tec Sidemount Diver program. Here you'll learn additional skills, such switching deco cylinders, and stage and switch deco cylinders.
How To Become A Sidemount Technical Scuba Diver Book PdfYou must be at least a level of fitness and health to dive. You may need to have written permission from your physician if you have chronic health issues, take certain medications or are recovering from recent surgery.
They are not issued unless earned. Not just taking part in the course does NOT guarantee certification. For cave courses certification cards may be available from multiple training agencies. C-cards can be purchased for around $30 depending on their agency. An instructor will be able to tell you more.
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.
Technical diving is fun, but not for those who want to dive deeper. Cave and decompression diving carry a greater risk. Dive planning and training are key to reducing this risk. These divers are held to a higher standard. To become a skilled diver, it will take practice. It is not possible to replace the time spent in water, no matter how much research you do. Divers will see that minimum standards are often exceeded by instructors during training courses. Technical training teaches diver redundancy. This allows problems to be solved at 1500ft in a cave, and then an exit can be made to the surface. Although it sounds scary and complicated, this is an essential aspect of diving in such an environment. Technical training is challenging, but also fun. The diver will have a golden ticket that opens up new areas of the world.
If you will not be using sidemount during your cave diver training, what you should be looking at is our CDS Basics Orientation course.
Divers who decompression dive use oxygen mixtures of every kind to prolong their time on the seafloor looking for wrecks and corals. The sport diver might only get two dives at 100ft, but a decompression diver can cruise for up to 60 minutes and still get the best bang for their buck.
I’ve just arrived on Malapascua Island in the Philippines, where over the next two months I’ll work my way up to becoming a Tec diving instructor. I’ve been a recreational instructor in Bali for the last two years and want to expand my experience and professional dive résumé. My first taste of technical diving was at Sidemount PCB, where PADI course director and Tec instructor-trainer Tom West molded me into a Tec-50 diver.
Technical diving is on the rise and Girls That Scuba HQ was quick to notice it! There were many questions to be answered and nerves to overcome so we decided to seek out Theresia, an Asian tech instructor. She is currently working at Blue Marlin Gili T, Lombok. She provided an introduction course in twin sets, and allowed us to dive into technical diving. Here's her lesson:
Different depths require the use of different gas mixes. The maximum partial pressure of oxygen a diver wants to dive at is 1.4 which is reached on air at 56m. Due to the water pressure the pressure of each individual gas increases and therefore we need to use appropriate mixes if we choose to go deeper. In general, the more oxygen a gas mix has the less deep we can go. A tech diver will use low oxygen mixes at depth and high oxygen mixes coming up shallower to off-gas Nitrogen faster and decrease the mandatory decompression time overall.
Sidemount diving can be fun, especially if your are a tec diver. Learn how to adjust your rig and how to get in the water with it.
Sidemount PCB is available to help you and your physician with questions about medical fitness for diving.
You can learn the SSI technical diver course and dive with up to four tanks (cylinders), for extended dives. The technical sidemount diver class is a great way for you to start technical diving. You will learn how to manage multiple cylinders during one dive. Also, learn how to configure your sidemount gear and set up a tec harness.
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.
from 170 to 350 feet
While conventional scuba diving has a recommended maximum depth of 130 feet, technical divers may work at depths ranging from 170 feet to 350 feet, and sometimes even deeper.
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.
