The Sea & Sea Sea Arm 8 Compact Digital Set is a modular system for connecting an external strobe to an underwater housing for a DSLR camera. The SA8 Compact Digital Set starts with the SA8 Camera Tray + Grip, an L-shaped component that connects (via a standard 1/4"-20 screw) to most compact camera housings on the market.
The set also includes an SA8 Fixed Ball Base, a 5.7"-long SA8 Double Ball Arm - Small, and an SA8 Strobe Head - Small. This last piece is used to mount a YS series strobe from Sea & Sea. Connecting components are two SA8 Ball Clamps, which can be tightened and loosened to enable adjustment of the arm's positioning.
Meticulously machined from a solid aluminum block, the SA8 system is highly rigid and at the same time extremely lightweight at only 1.2 lb.
