How I Transport S80 Cylinders Without Letting Them Roll Around the Car

Disclosure: This is an independent account of equipment I use or have used. I work in the diving industry and sell some of the brands or products mentioned, but I am not paid or sponsored to promote them and none of the equipment discussed here was supplied to me free. My preferences are personal conclusions from use, not universal buying advice.

Safety note: Equipment articles cannot replace formal scuba or technical-diving training, a manufacturer manual, a gas plan or a dive plan. Configuration choices must make sense for the diver, environment, team and training involved.

The workflow

Cylinders rolling in the back of a vehicle are noisy, inconvenient and potentially damaging to other equipment. I use one shaped support that I 3D-printed for each S80 cylinder. One is enough: the cylinder sits in the curved cradle and the support stops the routine sideways rolling that otherwise happens during transport.

The design is not about making the cylinders impossible to move in a crash; proper load restraint and vehicle safety still matter. It is a practical organiser that stops routine rolling and keeps the back of the vehicle more controlled.

The practical point

A simple workflow is valuable because it makes the correct behaviour easy to repeat after every dive.

The single 3D-printed cradle I use under each scuba cylinder to prevent it rolling in the car — This is the actual support I use. One shaped cradle is enough for each cylinder to stop routine rolling in the car.

An S80 should not become loose cargo

The same aluminium cylinder that becomes beautifully manageable in water is heavy enough to be dangerous if it rolls around a vehicle. I designed and 3D-printed a shaped cradle for each cylinder. I do not need two supports per cylinder: one correctly positioned cradle is enough to stop the cylinder rolling during normal transport. The solution is simple, tailored to the cylinders and removes a repeated nuisance every time I drive to a site.

This article is therefore as much about diving logistics as 3D printing. If an equipment problem repeats every weekend, solving it on land can improve every dive that follows.

The dive starts before the water and ends after it

Transport, rinsing and storage rarely look glamorous in equipment discussions, yet they determine how much effort a setup creates and how well equipment ages. My system is intentionally simple: two stackable plastic boxes. The larger box carries the suit, boots and BCD; the smaller box carries denser equipment such as regulators, fins and accessories. The separation makes the load more manageable and means I am not moving one enormous container every time.

The large box has a small drain valve in the bottom. At home it becomes a rinse tank. I fill it with fresh water, rinse the suit, BCD and boots, then work through the remaining equipment before opening the valve and draining it. The box therefore earns its place twice: transport and cleaning.

Cylinders need their own logistics

Aluminium S80s may feel beautifully neutral underwater, but they remain heavy projectiles in a vehicle. I designed and 3D-printed one support for each cylinder to stop it rolling around. That is a small example of the kind of equipment problem I enjoy solving: not buying another dive gadget, but making the complete process safer and easier from home to water and back again.

Rinsing is not servicing

Fresh-water rinsing removes salt and contamination; it does not replace inspection, scheduled servicing or correct drying and storage. Regulators should be handled so water is not encouraged into places it should not go, suits need to dry appropriately, and batteries/electronics deserve their own preparation. The principle is simple: maintenance begins with understanding what the equipment is designed to tolerate.

Good logistics buy more diving energy

Every unnecessary carry, tangled wet bag and rolling cylinder consumes attention before the dive or patience afterwards. I prefer solving those problems once with boxes, supports and a rinse routine. The reward is not a prettier garage; it is arriving at the water with more energy for the actual dive and getting home with equipment that is easier to maintain.
