A reticulating ball arm system is the best way to mount an external monitor. This allows the monitor housing to be moved in all directions - up, down, left, right, and rotationally - quickly and easily. The ball clamps can be loosened slightly underwater to allow one-handed repositioning of the monitor when changing shooting positions or to provide access to the rear housing controls.
For example, the monitor can sit above the housing when shooting a subject below you or directly behind the housing when framing macro. This avoids the awkwardness of re-learning how to aim your lens because your image is no longer in line with it.
The sliding ball mount allows for approximately 2.25" (5.7cm) left-to-right movement to offset the monitor for even easier access to rear controls.
A 3-point ball arm is the most ergonomic and versatile way to mount an HDMI monitor to your housing. The ball clamps can be loosened slightly underwater to allow one-handed repositioning of the whole monitor set-up when changing shooting positions or to provide uninhibited access to the rear housing controls. A top Cable Grip # 4080.09 is essential for carrying any system around on the surface in-between dives.
