TDI Sidemount Diver and Instructor Courses Released

Koh Tao, Thailand

Big Blue Tech is happy to announce the release of the TDI (technical diving international) Sidemount Course available to divers and instructors around the world.

This new course replaces the SDI Sidemount which will now be exclusively used for open water applications and not for technical diving combination.

This course is designed to teach certified divers how to safely utilize side-mounted primary cylinders as an alternative to the traditional back-mounted configuration.

This course provides the training required to allow candidates to competently and safely use sidmounted tanks to execute none overhead dives to a maximum depth of 45m. The course follows the advanced nitrox outline. The objective of this course is to train candidates in the proper techniques, equipment requirements and hazards involved in Sidemount diving for recreational and technical scuba. This course is run over 3 full days including academic presentations, equipment configuration workshops, 4 training dives and a final exam.

The other benefit of doing your course with BBT for your sidemount training is that we’re registered DiveRite Nomad Instructors AND Diverite distributors for Thailand. So when it comes to sidemount we have you covered.

All sidemount equipment for our training.

Whats is sidemount?

Side mount diving is increasing in popularity in both overhead and none overhead environments. Sidemount diving originated from the Sump diver across Europe who need to transport gear through dry passages and don the equipment again to pass the next Sump. Cave divers and wreck divers all over the world are now adopting this style of diving to open up access to challenging dive sites and for increased flexibility and comfort when traveling and diving tech.
