The Ollin SNAPSHOT BINO ADAPTER is built for many popular brands and sizes of binoculars and is designed to fit snug over the eyepiece. It is made out of ABS plastic which offers a good balance of impact, heat, chemical and abrasion resistance, dimensional stability, and strength. The patented magnetic design allows this system to be faster, more efficient, and more versatile than any other digiscoping adapter on the market today. The SNAPSHOT BINO ADAPTER requires a SNAPSHOT SNAPCASE (sold separately) for full functionality.
