DigIllum™ digital reticle illumination technology is available in select Nightforce riflescopes. As Nightforce’s premier illumination system, Digillum increases convenience and functionality in a single button control. Choose the appropriate illumination setting for your lighting conditions—either red or green, in five intensities from very dim to extremely bright. The illumination will turn off automatically after 1 hour or can be manually turned off to extend battery life. When illumination is turned back on, it defaults to your previously chosen setting, ensuring your night vision will not be adversely affected and that you’re instantly ready for a shot. Finally, Digillum is built into the side focus control, adding no additional width or extra knobs to the scope.
