Weefine Ball Arm (YS Ball Arm)

Underwater Photo Video ball light arm is constructed to be durable and lightweight. It allows expanding your underwater photo-video gear to your demands.

It's used for all kinds of lights, strobes, and other scuba photography gear.

The most common underwater photo video arm consists of two arms segments and three clamps giving you great flexibility. For instance, videographers sometimes use

Just one arm segment and two clamps since they do not need the same amount of flexibility as a still photographer does. The o-ring on the ball joints of the arms

like on every other ball joint component eliminates metal-to-metal contact. This allows a much more linear clamping force and controls the arm movement when

used with small or large heavier strobes even in varying current conditions. The ball joint ball size and adapters are a world standard 1" / 25mm.
