The OPSIN DNVM1 delivers a level of low-light performance previously unavailable to the traditional night vision market. It comes equipped with one of the most advanced low-light sensors available – the U. S. DOD approved Sionyx CMOS sensor. This provides outstanding detail and allows the user to observe targets well beyond what the human eye is capable of in moonless-starlight. The OPSIN is helmet mounted, and the external battery pack delivers a full eight hours of run time while also serving as a helmet counterweight. Other features include an onboard 32GB SD card for recording, and an integrated GPS module allows the user to document geo-locations. In addition, the OPSIN features a 44 degree field of view for enhanced situational awareness and better peripheral vision.
