With night vision goggles, you can in fact see in the dark, even without moonlight. Typically you can see someone 200 yards away, depending on the quality of the equipment. Night vision goggles are versatile as you can actually wear them or take them off and use them for handheld viewing.
Perhaps you are a private investigator or a work as a spy that conducts surveillance on a regular basis, night goggles are a must! if you are a PI that does not conduct surveillance they might not be necessary but they are sure fun to use! Those that aren’t in the spy field but just want to feel like it can just hang around in the bushes and spy on the neighbors! This may be considered unethical though! I’m just kidding!
