One of the big risks for a technical diver is decompression sickness. It occurs when nitrogen gas cannot exit the body thru respiration on ascent as the ambient pressure decreases. Therefore stops have to be executed on ascent in order to avoid a pressure difference too big so nitrogen bubbles can be formed. Buoyancy control is very important to control the stops on ascent and increase efficiency for off-gassing of nitrogen. Another important skill is proper breathing which makes metabolism efficient. Trim, which we call a proper tech diving position such as horizontal with a slight arch in the back, looking forward and knees at a 90 degree angle with fins pointing back. Trim prevents stirring up sediments on the bottom as well as most efficient movement in the water. And of course proper finning techniques to avoid overexertion are mandatory to make a diver achieve maximum performance. Now you might say, we want to have fun when we go diving and not be a machine.

Overhead diving professionals are allowed to use cave passages that were formed by millions of years worth of water erosion. They can be found thousands of feet away from the entrance. These sites are a treasure trove of beauty and tranquility, which was only possible because of the time it took to form them.

Cave Diving

If you plan to go sidemount, particularly if you are a tec diver already, you will need to learn about your new rig. How to adjust it, how it can be used to enter the water, and more.

Computer-aided instruction is an integral part of nearly every course we teach. The Why? is simple: eLearning helps get our students in the water sooner and spend more time there. It’s why we include the cost of any applicable eLearning programs — usually a $140 value — in our courses at no extra charge. This translates directly into an extra day of in-water training. The value of that? Priceless.

Sidemount Diving

Technical diving can be defined as being exposed to a ceiling that prevents a diver from ascending to the surface during a dive. This could be caused by a ceiling (in terms of a cave, a wreck, etc.) or a virtual ceiling that is created by a decompression duty. To avoid decompression sickness, it is necessary to perform mandatory decompression stops on ascent if you exceed the NDL. This requires special equipment such as a Twinset or Sidemount. Special equipment such as Twinsets and Sidemounts, gas mixtures with special properties, and additional training are required to be able perform the stops on ascent accurately to maximize Nitrogen off-gassing.

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.

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.

While technical diving is still for fun they aren’t for people wanting to go deeper, just because. There is a higher risk associated with cave and decompression diving. This risk is mitigated, in part, by thorough dive planning and training. As such, divers doing these dives are held towards a higher standard. It will take practice to become a technical diver. No amount of research and reading can supplement that in water time. Divers will notice that the minimum standards are often exceeded during training courses and individual technical instructors often do this. Technical training teaches a diver redundancy so that problems can be successfully solved 1500ft inside a flooded cave and an exit to the surface can be executed. While that sounds complex and scary it’s a necessary aspect of diving in that environment. Technical training is not only challenging but it’s fun and at the end of it the diver has a golden ticket to see parts of the world that are totally closed off to other people.

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.

Along with the Sidemount equipment that is specialized, you will also need your typical wetsuits, fins, masks, computer, compass, DSMB and other necessary equipment.

You can choose between recreational Sidemount or technical Sidemount with most agencies. Although the prerequisites are the same for TDI and SDI, the tec sidemount course will give you more skills. This course will require you to be more skilled in mastering the skills. You must maintain a perfect trim and keep your body level throughout.

Frequently Asked Questions

5-6 days
Rebreather training classes are typically 5-6 days long, but can be longer depending on a variety of factors such as the training agency, your local conditions, your instructor, and your ability to meet the class standards.

- Increased Bottom Time A Closed Circuit diver is not concerned with running out of gas because they are only limited by decompression. This can also be reduced by selecting an oxygen partial pressure that provides the diver with virtually limitless bottom times in 60 feet or less of water.

2-3 hours
Even with small cylinders, you can usually dive for 2-3 hours (rebreathers typically have two 2/3l cylinders or one 3/5l cylinder).
