The BROLIS TWINS is a dual tube highly advanced night vision device with Single Gain Control featuring very broad response range. The BROLIS TWINS are easy to use, operates from a single AA battery, has lightweight, extremely durable, Mil-Spec housing designed for multiple applications and is wear and corrosion-resistant. The BROLIS TWINS incorporate new high-performance optics that are not only much lighter but also offer higher performance than standard optics. Additionally, the BROLIS TWINS provide an automatic system power cutoff when the system is transitioned into the helmet’s mounted stow position, and then powers back on when it is flipped back down. This feature can additionally be disabled by the end-user if needed. The prominent feature is the integrated Auto-Gated power supply, facilitating operations under dynamic lighting conditions.
