Sidemount- Principles For Success
Sidemount won’t fix bad buoyancy. It amplifies it. Master basic skills in backmount first, then transition. When done right, sidemount feels like flying—not fighting your gear.
In backmount, a free-flowing left post is a disaster. You cannot reach it. In sidemount, every valve is within 6 inches of your shoulder. But simply being able to reach it is not enough. You need muscle memory.
In the early 2000s, if you walked onto a dive boat with two tanks strapped to your sides instead of your back, you were considered an outlier—a cave diver who simply hadn't learned how to socialize with "normal" recreational divers. 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.
Backmount buoyancy is simple: inflate wing, go up; dump wing, go down. Sidemount buoyancy is a physics puzzle because the weight of the gas moves as you move. Sidemount- Principles For Success
: Choosing between a minimalist harness or a fully featured BCD system based on your diving environment. Bungee Systems
The primary advantage of sidemount is the ability to achieve a perfectly horizontal profile. Unlike backmount, where the center of gravity sits high, sidemount places the weight of the cylinders along the diver's sides.
Do that, and you won't just be a diver with tanks on your sides. You will be a true sidemount diver. Sidemount won’t fix bad buoyancy
This is non-negotiable. It stabilizes the entire system and prevents the tanks from pushing the harness toward your head when horizontal. Cylinder Alignment
The single biggest mistake new sidemount divers make is over-rigging.
These offer more padding and integrated weight options, making them ideal for recreational or open-water environments. Cylinder Attachment When done right, sidemount feels like flying—not fighting
Clean hose routing is a hallmark of a pro. Long-hose configurations (typically on the right) and short-hoses with necklaces (on the left) ensure that you are ready for gas sharing without creating a "spiderweb" of hoses. 4. Gas Management and Balance
The long hose (typically 2.1 meters / 7 feet) routes from the right-hand cylinder, down the torso, up across the chest, around the neck, and into the mouth.
By carrying two independent cylinders, you have a fully redundant gas supply.
