The choice of equipment is very individual and different divers will recommend different styles. In general to go with a well known brand is useful as they stand for quality, performance and configurability. Some of the best brands are Apeks, Diverite, Halcyon, OMS, Scubapro, Hollis and some newer brands like xDeep or Tecline. The preferred divecomputers for tech divers at the moment are Shearwater products, whether it be the Petrel 2 or Perdix, the flexibility of the algorithm, handling and display.
There is a wide variety of equipment that is used by technical divers the biggest impact on the decision is the environment a diver is exposed to. Many cave divers prefer to use Sidemount which means, independent single tanks are mount to the side of the divers’ body and attached by clips on a D-Ring on the waist band on the harness and on the shoulder. This allows the diver to detach and don tanks to fit thru tiny restrictions and have a lower overall profile to go to places unreachable for divers who chose backmount. During multiple trips, additional tanks can be placed in a cave or a wreck to allow the diver deeper penetration dives and to pick up tanks when leaving the cave or wreck.

You will also learn how to use Sidemount regulators. Usually, you will have one regulator on a long hose as well as one regulator on a short hose with a necklace. Unlike your normal regs, Sidemount regs are also marked so you can easily distinguish which tank you are breathing from. During my training, this included a swivel joint for my short hose regulator. In addition, you will have 2 SPGs – one for each first stage.
Apart from the Sidemount equipment you will need your normal wetsuit, fins mask, computer, compass, DSMB, and other accessories.
Sidemount diving is also very popular, even in open water. Why? Because diving sidemount is very comfortable and easy to learn.
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.
The Sidemount diving setup is a little different from the setup when diving backmount and so is the equipment.
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.
Learn our SSI technical sidemount diver course and get the opportunity to dive with four+ tanks (cylinders) for extended dives. The technical sidemount diver course is an excellent way to get yourself into technical diving as it will train you to handle multiple cylinders on a single dive. Learn also on configuring your sidemount gear and setting up a tec sidemount harness as well as adjusting the sling tanks (cylinders) on your body.
Technical diving is a combination of passion, training, and experience. Technical diving is not for those who lack any of these three.
I'm not sure when or why I chose to take my Sidemount course. It was, as with many of my diving decisions. I think it was a case where I thought, "Oh, that looks cool. Could be useful. I'm going for it!" I knew Sidemount would be useful and something I could continue to use and improve on. Sidemount certification would be useful for me if I ever wanted to cave dive.
Do you want to become a Sidemount diver. You've come to the right spot, as this article will cover all the details!
I just arrived on Malapascua Island (Philippines) and will soon be working my path to becoming a Tec instructor. I've been working as a recreational instructor at Bali for the past two-years and would love to grow my professional experience. Sidemount PCB gave me my first taste in technical diving. Tom West was the PADI course director, and Tec instructor-trainer. He made me into a PADI Tec-50 diver.
