Razor Sidemount

Razor Basic Sidemount Open Water Course

Many years of experience and many hours of sidemount cave diving have led to the development of the Razor Side Mount System and further on to the development of the Razor Side Mount Open Water Course program.

During the course you will learn proper adjustment of the harness, cylinder configuration, regulator configuration, proper weighting and weight distribution for the best trim, regulator switches with one hand, different propulsion techniques, equipement failure handling (bungee, bolt snap, tank clamps, bat wing, regulators, etc.) as well as other general sidemount skills adapted to the use of the Razor system.

It is an advanced sidemount course for divers with an ample amount of sidemount diving experience. Owing a Razor sidemount harness is an advantage, but if you don't own one, you can also rent it (rental equipment is not included in the course fee).
