Product Description:
DT-NH8 is a new product developed based on the latest Optoelectronics technology. the magnification can be changed by changing the objective lens (or connecting the extender). It can be used with a gun sight holder, or it can be used alone. The night vision device has a built-in infrared and an auto brightness protection system.
This product has strong practicability and can be applied to military , coastal defense , public security , evidence collection, customs , etc. at night without lighting. It is good equipment for public security departments, armed police forces, special police forces, and guard patrols.
