DIVEVOLK Float Arm 447g and 872g Buoyancy for Underwater Photography

Achieve the perfect buoyancy balance for your underwater photography rig with the DIVEVOLK Float Arm. Available in two buoyancy ratings -- 447g and 872g -- these arms are engineered to reduce the effective weight of your housing and accessories underwater, giving you a more natural, neutrally buoyant setup that is easier to hold steady while composing shots.

Beyond buoyancy, the float arm doubles as a positioning arm for your dive lights. Its rigid aluminum construction lets you extend and angle lights precisely away from the camera axis, eliminating backscatter and delivering directional, professional-quality illumination. The arms connect seamlessly to standard ball-joint clamp systems, making them compatible with virtually any underwater photography rig.

FAQ

Which buoyancy rating should I choose?

The 447g arm suits lighter rigs -- a housing with a single light or lens. The 872g arm is better for heavier setups with dual lights, large dome ports, or multiple accessories. Aim for neutral buoyancy: total float arm buoyancy should roughly offset the negative buoyancy of your rig.

Can I use two float arms together?

Yes. Many photographers use a float arm on each side of their rig for maximum buoyancy and symmetric balance. The arms connect to standard ball joint clamps so they integrate easily into any arm system.

How do I maintain the float arm after a dive?

Rinse thoroughly in fresh water after every dive, paying attention to the ball joints. Allow to air dry completely before storage and inspect metal parts for signs of corrosion.
