The DTNVS is a lightweight folding binocular built on proven technology and enhanced for greater reliability verse previous generations of Night Vision Binoculars. The DTNVS binocular combines lightweight materials and a low profile when folded to the helmet which reduces neck strain during extended missions. The DTNVS binocular has a full feature set with individual sideways ON/OFF for each eyepiece and Flip-Up ON/OFF when folded up preventing backsplash on the helmet. To complete the DTNVSs’ features it incorporates built-in IR LED for close quarter missions with separate IR-ON indicator and low battery indicator in the field of view. No external battery port – Why? The DTNVS uses standard CR123A batteries as commonly found in lasers or flashlights. A single battery provides over 25h run time. However, as the pods shut off when flipped up and therefore halve the power consumption, most users report up to 35h on a single battery weighing in at only 17.9oz
