Buknoculars features an industry first technology, Primetime Color Vision. This patent pending technology drastically enhances low-light conditions to maximize every moment of shooting time. Quickly identify the target buck in vivid color when traditional optics only provide a graying silhouette. Primetime Color Vision does not use thermal imaging nor infrared, it is its own proprietary technology unlike any other. Video recording requires an 8GB-32GB Micro SD card (Micro SD not included).
