The EOTECH BinoNV is a cutting edge, compact, lightweight night vision goggle built to full MIL-SPEC standards. Binocular systems offer better depth perception than single tube systems making them preferred for navigating on foot or by vehicle and interacting with the environment. The built-in Diopter adjustments makes this model an ideal choice for special operations forces and SWAT applications. This goggle is fully articulable where the user can flip up each monocular easily and independently. This goggle features a self-contained single AA battery power and can also be operated with an external battery pack (optional accessory) for increased operational run time.
