The Twin-Task® Laser Flashlight series features powerful LED/Xenon® light, plus a pre-focused, visible red laser pointer that can pinpoint problems 100 feet away. Constructed from machined aluminum for strength and durability, these lights also utilize a micro-faceted reflector for smooth focus and an unbreakable glass lens. Flashlights are O-ring sealed to keep out moisture, too. The laser pointer is a 650 nM wavelength, Class 3AAA laser. Uses 3 AAA or 3 C alkaline batteries (included). Comes with their own lanyard and holster.
