The technical sidemount was completed the next day. This involved adding our 50-percent oxygen tank and 100 percent oxygen tanks to either side. This will increase your profile underwater. You must ensure that the tanks are as slim as possible. A couple of clips are located on either side of your waist. When your tanks become positively buoyant and you inhale, adjust the clip to match your tank position. It is important to keep your breathing as smooth as possible. Your breathing will change from one tank to another every few minutes. The pressure in each tank will drop at approximately the same rate. If a regulator or tank fails, you will still have gas to breath. Comfort and enjoyment can only be achieved by gaining experience. I spent the next few day doing deco dives using the sidemount rig with Evolution co-owner David Joyce, a Trimix instructor and Tec diver. We visited the Japanese Mogami wreck at 164ft, where I was charmed by the pieces of old gas masks and uniforms.

On top of this specialized Sidemount equipment, you will also need your usual wetsuit, fins, mask, computer, compass, and DSMB.

And then there are the rebreathers…a rebreather is a machine that recycles exhaled gas and is the preferred method for ‘very’ deep dives in order to use the gas carried more efficiently. In this case the exhaled gas is going thru a canister filled with a chemical which is called Sofnolime or scrubber to remove CO2 from the breathing loop and the remaining gas will be inhaled again by the diver. Metabolised oxygen is replaced into the loop to keep the oxygen content in the divers’ body at the desired pressure.

I took my first sidemount and technical sidesmount courses. Sidemount diving, like the name implies, requires you to place your tank on your hands. My hands and knuckles were completely covered by cuts at the end. The idea behind sidemount diving is to unclip your tanks and then place them in front you, Superman style. This will streamline your workflow. After making some adjustments to my harness size, the afternoon dive went more smoothly. I was now comfortable unclipping my harness and "Superman-ing” with the tanks. Sidemount gives you an amazing level of freedom, even if you have doubles on your back. Matt put up obstacle courses. We were soon flying through them with tanks in front, barrel-rolling, swimming upside down and tanks at the rear.

Sidemount divers tend to use two tanks. You can, however, use just one tank (I believe it's called the'monkey'), or use more than two tanks when doing deco dives.

Technical divers search for wrecks and reefs in depths below the recreational limit (40 m/130 ft). These divers have the ability to dive into underwater caves and other areas not accessible by regular recreational diving.

In addition, your Sidemount rig includes tank bands, clips, and probably some more bungees to stow away your regs nicely. The clips will be connected to your harness and again, their position is important for the position of your tanks.

For dives deeper than 56m gas mixes called Trimix are used. In order to reduce narcosis and reduce the toxic effects of Nitrogen and Oxygen, Helium is added which has no negative effect on our body to very deep depth. There are additional risks with helium but those start at depths of around 180m. In history tests have been executed with different noble gasses, however they all turned out to be toxic for the human body, so helium was the only one adequate for diving. One other gas that has no effect on the human body is Hydrogen but due to its high risk of fire and explosion in contact with oxygen, the blending of it is very difficult if not almost impossible with the techniques we use currently.

New gear means new techniques. Scuba diving sidemount is easy if you have the right skills.

The Sidemount diving setup differs from that used for backmount diving.

Academics – The academic parts of technical courses are similar to any other class in scuba diving. Students will learn from their instructors and do some self-study. Technical courses require a lot more planning than most people are familiar with, but they are crucial to a successful dive. Gas management will be a more involved part of overhead and decompression dives than many divers are used. The computer program calculates the required gas volumes and reserves for each dive.
