Bushnell Night VisionScope w/ Boom Microphone - $239.94
Let’s not dwell on why dad would want night vision, but just assume it would be used for good (gopher hunting, hilarious pranks, neighborhood “crime watch”). The scope uses but 2 AA batteries and sports a 2.5x42 (magnification x objective) lens with a range of up to 600 feet. It also has a directional microphone with a state of the art noise reduction system and recording capability. To be honest, I would think through the ramifications of giving something like this to dad if dating is something you enjoy.
