Sidemount- Principles For Success May 2026

Sidemount diving has evolved from a niche cave diving technique into one of the most popular configurations for technical and recreational divers alike. While the gear looks sleek, achieving true proficiency requires mastering specific fundamentals.

Think of the "Ghost Diver"—your body, backplate (if any), wing, and exposure suit. When you remove the cylinders, you should be able to hover in horizontal trim, motionless, with your hands at your sides or crossed on your chest. You should require zero fin movement to maintain depth.

As with any form of scuba diving, safety procedures are paramount in sidemount diving. Divers must learn how to handle emergencies such as equipment failures, air leaks, and navigation issues. They must also know how to perform safety checks, use backup systems, and communicate effectively with their dive team. Sidemount- Principles For Success

The Weighted Simulation

Before your first open water sidemount dive, practice on land. Put on your rig with full tanks. Sit on a bench. Close your eyes. Reach for your left valve. Now your right. Do this 50 times. Muscle memory is the only thing that will save you in zero visibility. Success means you never have to look or fumble to find which regulator is which.

A successful sidemount experience begins with a perfectly fitted harness that acts as a stable foundation for all other skills.

How to achieve this:

• Use a sliding D-ring or adjustable bottom clip mount on your waist strap. This allows you to move the tank's lower attachment point forward or back.
• For aluminum cylinders (negative when full, positive when empty): Start with the boot slightly forward of the valve. As the tank empties (becoming lighter), slide the bottom clip back to keep the tank from floating up into your armpit.
• For steel cylinders (negative throughout): Keep the cylinder closer to vertical. Steel tanks are your friend for trim; they rarely need aggressive tilt.

4. Don’t Fight the Cylinders (Performance Over Convenience)

The most tempting failure mode is to clip tanks low and back—what we call "the lazy tow." It feels easier on the shoulders. It hides the tanks in your armpits. It is also the fastest way to stir up a silty coffin. Use a sliding D-ring or adjustable bottom clip

Cylinder Positioning: Tanks should run parallel to your torso, not "butt-heavy" or floating up. Streamlining and Equipment Management
