How To Become A Sidemount Technical Scuba Diver Job Description

Technical diving refers to being exposed to a ceiling which prevents divers from reaching the surface at all times. This could be caused either by a physical ceiling such as a cave or wreck or a virtual one created by a dive restriction. If the NDL is exceeded, mandatory decompression stops must be made on ascent to avoid any decompression sickness. Most cases require special equipment, such as Sidemounts or Twinsets. To optimize Nitrogen offgassing, Twinsets or Sidemounts are necessary.

Sidemount diving can be done by anyone who is an Open Water Diver. While it is essential to have good buoyancy and trim, you will be able setup and handle your equipment by yourself. Sidemount diving is a great way to expand your skills and knowledge in equipment setup.

We can offer the SDI course if requested. However, we only offer the TDI course by default. This can be taken as a stand-alone program, but our students usually combine it with the Apprentice Cave Diver course.

One of the big risks for a technical diver is decompression sickness. It occurs when nitrogen gas cannot exit the body thru respiration on ascent as the ambient pressure decreases. Therefore stops have to be executed on ascent in order to avoid a pressure difference too big so nitrogen bubbles can be formed. Buoyancy control is very important to control the stops on ascent and increase efficiency for off-gassing of nitrogen. Another important skill is proper breathing which makes metabolism efficient. Trim, which we call a proper tech diving position such as horizontal with a slight arch in the back, looking forward and knees at a 90 degree angle with fins pointing back. Trim prevents stirring up sediments on the bottom as well as most efficient movement in the water. And of course proper finning techniques to avoid overexertion are mandatory to make a diver achieve maximum performance. Now you might say, we want to have fun when we go diving and not be a machine.

While technical diving is still for fun they aren’t for people wanting to go deeper, just because. There is a higher risk associated with cave and decompression diving. This risk is mitigated, in part, by thorough dive planning and training. As such, divers doing these dives are held towards a higher standard. It will take practice to become a technical diver. No amount of research and reading can supplement that in water time. Divers will notice that the minimum standards are often exceeded during training courses and individual technical instructors often do this. Technical training teaches a diver redundancy so that problems can be successfully solved 1500ft inside a flooded cave and an exit to the surface can be executed. While that sounds complex and scary it’s a necessary aspect of diving in that environment. Technical training is not only challenging but it’s fun and at the end of it the diver has a golden ticket to see parts of the world that are totally closed off to other people.
