XSearcher-4S -- head only -- with 66mm convex lens for Night Master 800-4S
The XSearcher-4S head is an add-on for the Night Master 800-4S and '800-4S-IR models. To use, you simply unscrew the Night Master-4S head and replace it with this one - using your existing LED. It uses a 66mm convex lens, compared to a 50mm lens in the Night Master-4S. This bigger lens provides a tighter beam and more distance. Despite being bigger, there is still sufficient clearance from a scope's 56mm objective lens when using the high scope mount supplied in the Night Master 800-4S kit. This will ONLY fit the 4S model.
