The 4.5x60 Challenger GS NV Monocular from Pulsar is a first generation night vision device including built-in infrared illuminator. The 4.5x optics are well-suited for mid-range tasks requiring moderate magnification while still preserving some situational awareness. Two 1/4" tripod mounting sockets enable the monocular to be mounted in front of either eye and will also accommodate accessories, like a long-range IR illuminator or laser aiming device, on the mount not in use. The weather sealed housing and angled rubber eyecup make the Challenger GS a useful night vision monocular for low-light hunting and other recreational applications.
