Magview S1 Sync Features The Magview S1 Sync uses a self-aligning magnetic system that lines up the phone with the optic for faster more accurate digiscoping. Built-in rare-earth magnets connect the device without bulky adapters or cases so there is little to fumble with in the field. The user flips open the cap connects the phone and SYNC takes care of the alignment so the shooter is always ready to capture the moment. The adapter fits eyepiece sizes from 51mm to 60mm. The kit includes the Spotting Scope Adapter sizing rings eye-relief spacers and a phone plate along with the SYNC auto-aligning phone disc and an alignment tool. Made in the USA from polymer in a matte black finish the adapter is built for hunters and birders who track elusive game or rare species. Magview designed it to keep the phone securely in place even in rugged conditions so the user can focus on the subject instead of the setup. It weighs well under a pound.
