MarkO is a long range CLIPON cooled TI Sniper Sight. It allows a sniper to recognise human targets at more than 2km. Its compatible with most telescopic sights used on sniper rifles. It is successfully tested on weapons upto 12.7mm caliber.
The CLIPON capability allows a sniper to use the TI capability whenever required in field without the need for any zeroing. This also ensures the sniper can use the same reticles on the telescope.
MarkO can also be used as a handheld long range TI monocular.
