Product Description

This clear acrylic dome end cap is for use with the Watertight Enclosure for ROV/AUV (4″ Series). The dome shape reduces drag on your vehicle, and allows for extra room within the enclosure for additional electronics, sensors, or a camera! It has a wider field of view than that of a flat end cap. It’s optically clear and won’t warp or distort your footage.

This dome as been extensively pressure tested in the Crushinator and is rated to 500m (1640 ft) water depth.

Compared to our original 4″ Series dome, this dome has a new design with a separate dome and retaining ring, providing a robust and simple seal and installation.
