Nightmaster-4S -- Head ONLY
The Night Master 800-4S head is an add-on for the XSearcher-4S. To use, you simply unscrew the Xsearcher-4S head and replace it with this one - using your existing LED. It uses a 50mm convex lens, compared to a 66mm lens in the Xsearcher. This will ONLY fit the 4S model.
