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.

Today, sidemount diving has exploded beyond the sump and the cavern. It dominates technical wrecks, penetrates pristine coral reefs, and is rapidly becoming the configuration of choice for solo divers, photographers, and even warm-water vacationers. Sidemount- Principles For Success

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
Take these principles to your next pool session. Not a deep dive. Just a pool. Strip down to the Ghost Diver. Pass that test. Then add one cylinder. Adjust the Leaning "L." Clip and unclip until your hands bleed (figuratively). Then add the second cylinder. Simulate a valve shutdown fifty times. In the early 2000s, if you walked onto
