FLIR’s BHM-Series bi-ocular thermal night vision system is their best handheld search and rescue tool yet. Compared to monocular (one eyepiece) cameras, the BHM’s unique bi-ocular (dual eyepiece) design is less tiring to use over long voyages, easier to hold steady on rough waters, and gives you greater range performance. The available high-resolution 640 x 480 thermal sensor gives you four times the resolution of other FLIR handhelds. Plus, the quick connect lens options (sold separately) allow you to choose the right lens for each application. Choose the wide angle 35mm lens to scan large expanses of water, the 100mm lens for a narrow field of view and superior range performance, or the 65mm for a balance of range and viewing angle. Regardless of the camera and lens combination, the BHM-Series provides you the confidence that comes from being able to see clearly in total darkness.
