Sidemount diving has quickly gained popularity by both recreational and cave divers due to its many advantages over standard back mounting configuration which, apart from being able to reach lower and tighter sections of caves, can be broken down into three areas:

1. Safety: Sidemount configuration provides a completely redundant and independent air system with the valves, regulators, and hoses in plain view and easy to reach should a problem arise.

2. Control: Sidemout configuration enables buoyancy, balance, and trip control resulting in a much more streamlined profile making moving through the water easier and more efficient.

3. Comfort: Single tanks can be easily transported to and from the dive site thereby reducing strain on the diver’s back, knees, and ankles from carrying loads long distances.

The primary focus of sidemount training is to offer the diver who has never tried it before an introduction to diving in sidemount configuration in open water. For the diver with a cave certification, the sidemount course will teach the skills and procedures necessary to cave dive in sidemount configuration but still in larger caves as it takes time to fully master any new equipment configuration before moving on to the Advanced Sidemount Diver Course, which is a more intensive and demanding course requiring a high comfort level in a more challenging and fragile cave environment and the ability to dealing with possible stressful situations​.
