Float arms

Float arms are buoyancy arms that add lift to an underwater camera rig. They combine arm and flotation in one component, helping to balance housings, strobes and video lights during dives. Unlike separate float accessories that mount onto existing arms, float arms integrate buoyancy directly into the arm itself.

Common questions about float arms and buoyancy systems

What is the difference between float arms and float blocks?
Float arms combine the arm and buoyancy in one component. Float blocks are mounted onto existing arms to add lift without replacing the arm system.

When should I choose float arms instead of float blocks?
Choose float arms when building or replacing an arm setup. Use float blocks when you already have arms and only need extra buoyancy.

How much buoyancy do I need?
This depends on the weight of the housing, strobes, video lights and accessories. A balanced setup should feel stable without pulling strongly up or down.

Can I combine float arms with separate buoyancy floats?
Yes. Float arms can be combined with separate floats to fine-tune buoyancy, especially on heavier underwater camera systems.

Are float arms compatible with standard trays and clamps?
Most float arms use standard ball connections and clamps, making them suitable for many modular tray and arm systems.
