Sidemount specialty course

Take the first step to become a Technical Diver. Don’t miss the TDI Sidemount specialty course! Increase your safety by wearing “double gas”.

Learn new diving techniques with our technical diving instructors, such as the handling of two bottles underwater. Enjoy the advantages and comfort sidemount diving has to offer.

This course is designed so that divers, both recreational and technical, learn carry scuba tanks anchored to the sides.
This technique was designed for the comfort of recreational divers, so they don’t need to carry the bottle in their backs, in addition to being able to easily remove it and put it back on in order to climb up or down the boat, and without losing the positive buoyancy the system has in the surface . And of course, for cave diving where the channels are restrictive and difficult to dive into with two bottles on the back.
A different configuration for a more comfortable and safer dive.
