The Buck Lantern hunting headlight kit is the first of its kind. It was designed with the deer hunter in mind, but its possibility of uses are endless in the world of hunting and outdoor activities. It features an adjustable focus with three modes: bright white, dim white and bright red. The battery compartment is rainproof to protect the included pair of rechargeable 18-650 batteries. The included charger hooks directly into the battery compartment and will allow for charging in your vehicle or from your wall outlet. The Buck Lantern now has a Built In Halo Shield that controls the light so it only goes where you want it to go.
