How To Become A Sidemount Technical Scuba Diver Life Expeditions

Next, it was time to do technical sidemount. This involves adding our deco 50-percent and 100-percent oxygen tanks on each side. You will have a higher profile underwater, so it is important to keep the tanks as close to your body as possible. There are two clips at each side of the waist. You adjust the tank position by inhaling down your tanks. This is where simplicity is key. You also need to switch between tanks every few minutes. This ensures that the pressure in each tank is at the same level, so even if one tank or regulator fails, there will still be gas for you to breathe. Building up experience is the key to comfort, enjoyment and success with new technologies. The next few days were spent doing sidemount dives, budding up with Evolution coowner David Joyce, a highly experienced Tec diver and Trimix instructor. One dive took us to the Japanese Mogami Wreck at 164 feet. I was captivated by the old gas masks, uniforms, and bones that we found.

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.

Television, magazines, and stories from a friend are all good sources of information about the underwater world. Exploring it and getting away from the surface can be exciting. How do we keep exploring? What exactly is technical dive?

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.

By allowing divers to exhale gas, the rebreather can extend their diving capabilities. The rebreather will then recycle the gas and inject the required amount of gas into the cylinder. This can dramatically increase the dive time when compared to using double the size and weight cylinders, especially for deeper dives. You can have rebreathers back- or sidemounted. The profile they create will depend on their configuration.
