GELIOS 3 is a lightweight and compact night vision monocular intended for observation in low light environments as well as complete darkness. It features two switches conveniently placed for easy operation. The first switch turns on the NV device and allows for low-light applications. The second switch activates the Infra Red illuminator allowing operation in situations where no light sources are present. You can engage one or both of the switches based on the particular situation, conserving the energy and prolonging the battery life. The IR illuminator is built-in and does not require an additional set of batteries.

GELIOS 3 is equipped with automatic light protection circuit, which disengages the power in the event of exposure to intense light, where as a unit lacking such protection could be rendered inoperative.

Features a hand-strap for secure and steady navigation and comes in its own protective carry pouch.
