The Ollin SNAPSHOT SPOTTER ADAPTER is built for many popular brands and sizes of spotting scopes 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. This kit includes the SNAPSHOT PROTECTIVE CAP which can be used to keep dirt, debris, and moisture away from your optics lenses while on the move. The patented magnetic design allows the Snapshot system to be faster, more efficient, and more versatile than any other digiscoping adapter on the market today. Also included is an adjustable tether to connect your lens cap to your optic to keep it secure and safe while on the move. The SNAPSHOT SPOTTER ADAPTER requires a SNAPSHOT Phone SNAPCASE (sold separately) for full functionality.
