The B1 XL Binocular Adapter was designed to be the sleekest digi-scoping system available on the market. Impossibly small yet impressively strong, the B1 Adapter seamlessly integrates with your binoculars of choice. Slip it onto the eyecup and tighten the retaining screw. That’s it. A set it and forget it design does not impede normal use of the binocular, making this tool an efficient and practical addition to your kit. Together with the MAGVIEW Phone Plate, this system creates the ultimate light and fast digi-scoping platform for steady, sharp photos and videos, every time.

• Fits eyepiece sizes 44mm-48mm (1.73in-1.89in)
  The plate is made of stainless steel and the magnets live in the adapters, not on your phone, do not interfere with signal, and is secured with a simple adhesive. 
• Plate size 2.5″ x 3.25″
• Includes: B1 XL ring and MAGVIEW Phone Plate
• Made in the USA

*Please note the MAGVIEW Phone Plate is not compatible with wireless phone chargers*
