Sightmark Ghost Hunter 2x24 Night Vision Monocular SM16012 can function as a purely observational tool or as a sighting accessory to your rifle. This night vision monocular allows you to view targets with great clarity, even at range, thanks to the monocular's high resolution and built-in IR illuminator. Use the included weapon mount to attach the Sightmark 2x24 Night Vision Riflescope to the rifle of your choice; this Sightmark night vision product can be used in conjunction with a holographic or reflex sight for maximum accuracy. Sightmark has also included an automatic shut off feature in this unit, so the rifle scope will preserve the night vision intensifier tube when it encounters bright light. For medium range accuracy in the blackest of nights, the SightMark Ghost Hunter 2x24 IR Illuminator Riflescope is an excellent option.
