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.
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?
