Benefits

Flexibility

Sidemount diving offers some benefits in the flexibility of equipment. Cylinders suitable for sidemount diving are usually freely available for rental, unlike manifolded twin sets for back mounted use, which allows the traveller to conduct technical or overhead environment dives without having to source twin cylinder sets. When diving in remote locations, the transportation of single diving cylinders, especially by hand, may be less physically taxing. Sidemount harness can be lighter and less bulky than back-mounted alternatives – allowing for easier and cheaper air travel.

Accessibility

Unlike back-mounted cylinders, the sidemount diver has immediate access to, and can see, the regulators and tank valves of their cylinders. This enables quicker and more certain problem identification and resolution, without requiring ‘behind the head’ shut-down drills that require a higher level of joint and suit flexibility and the ability to identify and correctly operate equipment which is out of sight.

Low profile

Sidemount diving configuration places the cylinders under the diver’s armpits, in line with their body, allowing the diver to pass through smaller restrictions than would be possible with back-mounted cylinders. The ability to remove tanks and push them in front allows the diver to pass through very small passages and holes when penetration diving – being limited only by the bulk of their bodies and diving suits.Streamlining for reduced drag while swimming is not always achieved.

Safety

Increased accessibility to regulator first-stages and cylinder valves improves efficiency and speed of critical cylinder shut-down procedures, allows immediate gas-loss identification and provides the diver with quick access to alternative contingency procedures, such as swapping regulators between cylinders, manual operation of a cylinder valve to control gas flow through a regulator which is free-flowing, or to allow breathing directly from the tank valve.

Mounting the cylinders at the diver’s sides reduces exposure of valves and regulator first-stages to impact and abrasion damage, or accidental shut-down through roll-off against a ceiling. It also significantly reduces the risk of entanglement behind the diver, where it is most difficult to rectify.

Comfort

Some divers will testify that sidemount diving configuration offers greater stability and easier-to-attain trim and control in the water. It is also claimed to be less physically tiring to carry, and get into, sidemount equipment than back-mounted doubles – especially when operating from a small boat or a rough shore entry.

The ability to attach, remove and replace cylinders while in the water allows the diver to avoid carrying twinned cylinders. The reduced physical exertion when conducting regulator shut-down procedures is a major benefit to divers who suffer from shoulder or back discomfort or reduced mobility.

Redundancy of gas

Technical divers have generally used a redundant gas supply system, either isolation-manifolded or independent back-mounted cylinders. Recreational divers have traditionally resorted to using buddy supplied gas, or relatively small bailout ‘pony cylinders’ or ‘ascent bottles’ for out-of-air emergencies. Whether attached to the primary cylinder, or slung at the chest, these cylinders often present problems with stability and streamlining, whilst not always providing more than a bare minimum supply of air for emergency ascent. Sidemount diving with two equal-sized cylinders helps resolve stability and streamlining issues, and can ensure that an adequate redundant reserve of air is maintained, similar to back-mounted twins

Back-mounted manifolded cylinders provide easy access to the whole gas supply in the event of a regulator failure and shut-down. However, the manifold itself creates additional potential o-ring failure points, and a major leak at the manifold will deprive the diver of at least one-half of the remaining gas supply. Independent cylinders, when sidemounted, provide more reliable gas redundancy, and allow greater access to all remaining gas by switching regulators between cylinders or feather breathing, provided the diver is competent at the additional skills required
