The Bushnell Binocular Tripod Adapter easily mounts most binoculars to tripods or window mounts. Simply thread the adapter into the tapped hole located between the objective bells of most binoculars and then attach the adapter to any tripod or window mount. If you spend extended periods of time glassing through binoculars, this adapter will ease the eye strain and is perfect for digi-scoping applications with binoculars. Note: Not all binoculars are tripod adaptable
