Float Ball Arm 4522HD (buoyancy +230g), 28cm

Buoyancy Arm 4522 HD – Your Key to Perfectly Balanced Underwater Photography

The Buoyancy Arm 4522 HD is your ideal solution for creating a lighter, more ergonomic underwater camera setup. Thanks to its innovative design, featuring ultra high-density foam and an internal aluminum spine, it provides significant lift without the common weaknesses of conventional hollow carbon arms. No more worries about water infiltration or damage from bumps.

Why Choose a Foam-Filled Arm Over a Hollow Arm?

Traditional carbon arms with hollow chambers can take on water if they develop cracks or suffer impact. The solid 4522 HD design eliminates this risk entirely. Made of highly compressed foam, it’s immune to water ingress and able to withstand pressure points or sharp objects without compromising its buoyancy. That makes it extremely robust and ideal for airline travel, where delicate gear is always at risk.

Maximum Lift with Minimal Weight

Modern underwater camera housings and video lights are becoming increasingly compact, but often end up negatively buoyant. This can lead to diver fatigue and increased air consumption. A neutral or slightly positive buoyancy setup, on the other hand, enhances comfort and makes diving more enjoyable. The Buoyancy Arm 4522 HD significantly reduces the in-water weight of your camera rig, making it easier to handle.

Key Advantages at a Glance

• Exceptional Durability: Reinforced aluminum spine and ultra high-density foam construction.
• No Hollow Interior: No risk of water ingress or internal damage.
• Greater Buoyancy: Produces substantially more lift than many arms of similar size.
• Improved Ergonomics: Reduces rig weight underwater, easing strain on wrists and arms.
• Ideal for Travel: Resistant to shocks and pressure, making it perfect for flight check-ins.

Less Effort – More Enjoyment

By achieving neutral or slightly positive buoyancy for your camera system, you can dive longer with less fatigue. You’ll also find it easier to keep your camera stable, resulting in sharper images and smoother video footage—vital for capturing the best possible underwater photography and videography.
