The world of night vision is nothing short of incredibly cool... And complicated... The good news is we have people like Instructor Mike Griffin who have dedicated themselves to figuring it all out and presenting it in a way that makes sense to those who are just beginning to scratch the surface. In this episode of our "New to NODS" series, Mike talks about the differences between traditional analog or "i-squared" night vision and thermal. What are the key differences, pro's and con's of each system, and what would be best for you to go out and purchase as your first big investment in night vision and technological sighting devices?
