Marathon 7x50mm BAK-4 Prism Binocular W/Compass BI030017

This waterproof binocular is designed for military professionals. The model features a navigational compass with backlight built into the viewing optics, as well as vertical and horizontal NSN reticles to assist in measuring distance during operation. This binocular is also specially designed with a magenta lens coating to increase image brightness.

Engineered with a premium BAK-4 prism, it offers an excellent viewing experience with superior light transmission and less peripheral light being lost due to internal reflection. This binocular is built to thrive in any environment; waterproof and submersible to a depth of 0.5m for up to 20 minutes, and featuring a nitrogen-filled case to prevent fogging of the lenses during changes in heat or humidity.
