Sightmark SS280 Triple Duty Tactical Flashlight SM73005 adds extra functionality to your standard tactical flashlight. A selector switch cycles the Sightmark flashlight through three different settings--strobe, 100 lumen, or 280 lumen--each with different applications. Use the strobe to attract attention in emergency situations, to disorient targets, or as a decoy. The included blue, red, and green filters extend the flashlight's uses even further; the red filter is good for tracking targets while preserving your night vision, the green filter can be used to read maps, and the blue filter is good for following a blood trail from an injured target. Since the Sightmark SS280 Flashlight is designed to be mounted on a weapon with a separately sold flashlight accessory, it is constructed of high grade aircraft aluminum that can withstand recoil. The Sightmark SS280 Triple Duty 280 Lumen Flashlight is waterproof, corrosive resistant, and an indispensable accessory for a wide range of hunting, camping, personal safety, and tactical situations.
