Sidemount is a great option for cave diving, as it can offer many benefits to divers. Sidemount was invented by cave divers. These are just a few of the many benefits.
The next day it was on to technical sidemount, which means adding our deco 50-percent oxygen and 100-percent oxygen tanks on either side. This increases your profile underwater so you must keep the tanks as trim as possible against your body. You have a couple of clips on each side of your waist. As you breathe down your tanks and they become positively buoyant, you adjust your tank position to the second clip position. The aim here is to be as streamlined as possible. Every few minutes you also switch your breathing from one tank to the other. That way the pressure in each tank runs down at roughly the same rate, and if there is a failure with either tank or regulator, you’ll still have gas to breathe. As with all new things, building up experience is key to comfort and enjoyment. I spent the next few days doing deco dives with the sidemount rig, buddied up with Evolution co-owner David Joyce — a hugely experienced Tec diver and Trimix instructor. On one dive we visited the Japanese Mogami wreck down at 164 feet, where I was beguiled by the bits of old gas masks, uniforms and even a few bones we saw.
Technical Sidemount DivingPADI Training is available for both Android(tm), and Apple(r), iOS devices. Devices should not be older than three years old and have the latest OS (operating systems).
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.
You will need your standard wetsuit, fins and mask as well as a computer, compass and DSMB.
Skills (generally) - An introductory tech diver will practice his trim and buoyancy using the new equipment configuration. This is the first step to efficient diving. Once this foundation is established, the student can begin practicing locomotion before moving on to more advanced skills.
Technical divers are able to explore wrecks and reefs at depths that are below the recreational limit of 30 m/130 ft. Specialized training allows them to explore underwater caves, and other places that are beyond the reach of recreational diving.
Whatever configuration a diver chooses there is benefits for each and in different situations each configuration has its up or downside.
One of the most significant innovations in equipment cave divers have seen since the beginning of this century has been the transition from backmounted to sidemount doubles. Many cave divers now sidemount. There may even be more open-circuit sidemount cave divers that backmount cave divers.
To become a technical diver, you need to have passion, experience and training. Technical diving can be dangerous if one or more of these factors is lacking.
We do not issue certification cards unless they are earned. The mere fact that you have taken part in a training course does not make you certified. There may be multiple certification agencies that offer certification cards for cave courses. C-cards typically cost $30 each depending on the agency. You can ask your instructor more.
Most agencies allow you to choose between technical Sidemount or recreational Sidemount. While the prerequisites for SDI and TDI are identical, the tec Sidemount course will require more skills. You will need to master them more - perfect trimming and maintaining a level of skill is essential!
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.
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.
Technical diving (also known as tec diving or tech diving) is non-professional scuba diving that exceeds the agency-specified limits of recreational diving.
