Sidemount- Principles For Success Today

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.

Why is this critical? Sidemount tanks are slung alongside your body. They are not structural elements of your trim. If you rely on tank position to fix a head-up or feet-down posture, you are building a house on a cracked foundation. As you breathe down the gas (changing tank buoyancy), or if you donate a tank to a buddy, your center of gravity will shift unpredictably. Strip your rig to the bare essentials (wing, harness, backplate). Perform a weight check. Adjust your ballast so you can hold a 10-foot stop with an empty wing. Only then should you clip on your sidemount cylinders. Sidemount- Principles For Success

Success Principle: Trim is a property of the diver, not the tanks. Recreational backplate divers love their continuous webbing—one piece, no padding, minimalist. In sidemount, you cannot simply thread the same rigid straps sideways. The human torso is conical, and your shoulder blades move. A poorly fitted sidemount harness will rotate tanks into your armpits, pinch your neck, and cause lower back pain. Think of the "Ghost Diver"—your body, backplate (if

If you clip a cylinder to your chest D-ring and bottom clip, but the tank's center of buoyancy is behind your center of gravity, you will roll onto your back (feet up, face to the sky). If it is too far forward, you will pitch head-down. Why is this critical
