The New FLIR H-Series Bi-Ocular from US Night Vision Corp. is a handheld thermal imager providing the same performance and image clarity as the original H-Series monoculars. Incorporating the use of both eyes, the Bi-Ocular’s high performance core allows officers to see in total darkness and through many atmospheric conditions. Employing a 320 x 240 or 640 x 480 resolution, the Bi-Ocular comes in two models, the BHS-X and the BHS-XR. The thermal imagers feature a quick disconnect lens, extended range options with a 2x and 4x (varies by model) digital zoom, faster recharging and one-touch recording.
