How can civilians be able to have afford a night vision device since the good ones are not cheap. In this episode of Defrowe Airsoft, Nick Chen talks about how to setup one... "Night vision can be confusing to understand, especially when it comes to the different types of goggles available. In this video, we discuss the two types of night vision goggles available in the US, the military designations and the commercial goggles. We also discuss the PVS 31 Alpha, which is a popular model of night vision goggle, and the performance differences between a 6,000 and 13,000 goggle. We also talk about the importance of looking cool when it comes to night vision goggles and the different specs available. Lastly, we discuss a true budget build and how it can still be used to see in the dark."
