The Magview B1 XL Binocular Adapter is the larger-eyecup version of the B1 digiscoping mount from Magview, built to fit eyepiece sizes from 44mm to 48mm (1.73 to 1.89 inches) (brand part no. 82016). It slips onto the eyecup and tightens with a retaining screw for a secure, set-and-forget fit that does not interfere with normal binocular use. Paired with the Magview Phone Plate, it creates a light and fast digiscoping platform for steady photo and video through larger binoculars that the standard B1 does not fit. It is a straightforward upgrade for hunters running larger-eyecup optics who still want a reliable phone-mounting solution.
