What do you plan to dive in? (e.g., open water, wrecks, or caves)
A single length of shock cord running across the back and under the arms. This provides excellent flexibility and keeps the valves tucked tightly into your armpits for maximum streamlining.
Because your tanks are not connected by an isolation manifold like backmount doubles, you must manually switch regulators to balance your gas consumption. The verified protocol is to never let the pressure differential between your left and right cylinders exceed 30–50 bar (500–700 psi). sidemount principles for success verified
90% of sidemount problems are rigging problems, 9% are buoyancy problems, and 1% are true emergencies.
The following principles have been verified through thousands of cave dives, wreck penetrations, and open water technical dives. They are the non-negotiable pillars of mastery. What do you plan to dive in
Sidemount diving involves carrying scuba cylinders on the sides of the body, rather than on the back. This configuration allows divers to swim more efficiently, with their body positioned horizontally, and their center of gravity aligned with the direction of travel. Sidemount diving has become increasingly popular among technical divers, wreck divers, and explorers, as it offers improved mobility, reduced drag, and enhanced safety.
Can you easily reach and manipulate both cylinder valves with either hand? Because your tanks are not connected by an
The first and most fundamental verified principle is the mastery of . In backmount, the tank’s weight sits along the spine, creating a natural but rigid pivot point. Sidemount, conversely, distributes weight low and along the diver’s sides, shifting the center of gravity downward. Successful sidemount divers understand that they must be “neutrally buoyant and horizontally trimmed” before they even touch their tanks. The verified method involves positioning the cylinders’ valve necks close to the armpits, with the cylinder bottoms resting near the hips. This creates a “pocket” of stability. Any deviation—tanks too high or too low—introduces a rotational torque that forces the diver to fight a constant head-up or feet-down attitude. Verified by countless pool sessions, the rule is clear: when you let go of the valves, the tanks should not roll or slide; the diver’s body remains a motionless, horizontal reference plane. Without this stability, all other sidemount skills become exercises in frustration.
The stainless steel worm clamp or hose clamp holding the bolt snap should be placed precisely to allow the cylinder to hang at the correct height (valves just below the armpit) [4].
A verified sidemount setup is free of "danglies." Every piece of equipment—from backup lights to reels—is tucked away or clipped off in a specific, repeatable location. Hose Routing:
