The Amphibious Scope CX from Vixen is designed for underwater observation and investigation tasks that involve water tanks, boat hulls, bottom structures, fishing areas, sea farms, or any other aqueous environment. The CX scope can also be used for terrestrial periscopal viewing.
When immersed in water, the CX magnifies the scene by 1.33x, whereas on land it produces unity magnification of 1.0x. The CX's FOV is also contingent upon its viewing environment; 45° on land, 35° underwater. This clever waterproof optic measures 1.4"/3.5 cm in diameter and 56"/142 cm in length.
Turning the CX's tube changes the scope's viewing orientation from 90° to straight-through. In straight-through mode the image is reversed - the 90° angled view will be inverted.
