The Tag-7 Thermal Acquisiton Goggle systems are complete, self-contained thermal units that only require 2 AA batteries to function and. The goggle uses the same headmounts/helmet mounts and other accessories as a standard PVS-7 goggle. The thermal goggle provides a bright clear picture of the suroundings unaffected by lights or shadows that will render image intensified night vision useless. Camoflage will not be an asset against the sensitivty and deteciton capability of these units. Made using the latest in DSP technology and lightweight materials, the NIVISYS goggles are small and comfortable.
