Explore the outdoors at night using the compact and water-resistant Nightfall 4x50 1st Generation Night Vision Monocular from Firefield. With a built-in infrared illuminator and a 1st generation intensifier tube, you obtain detailed images of night scene, improved range, and adequate visibility in complete darkness. The IR illuminator allows you to illuminate your target and make your observations in complete darkness while you remain unseen. This way, at night, you can use this night vision monocular to watch live animals on your backyard, or see intruders and trespassers on your property. The viewing experience is enhanced with a 15° wide angle of view, 4x magnification, and 50mm objective which increases light gathering capacity. Additionally, monocular features a 12 mm eye relief to accommodate viewing with eye glasses.

Beyond optical performance, the monocular features a number of convenience features. The objective cup has a rubberized covering and can be rotated to adjust coarse. Once you have made your coarse adjustments, you can use the diopter adjustment to fine-tune your focus. The water resistant housing protects your device from splashing water like rain and sprinklers, the rubberized armoring provides a secure non-slip grip, and slender body allows you to hold it with one hand and access to menu buttons at the same time. For long-term observation, improved image stability, or multitasking, this monocular can also be mounted on a 1/4"-20 tripod via a built-in socket. Also included with the monocular are a hand strap, a carrying case, a cleaning cloth, and an objective cap.
