The Magview S1 and S1 Mini now features SYNC - the self-aligning magnetic system that aligns your phone with your optic for faster, more accurate digiscoping. Built-in rare-earth magnets seamlessly connect your device without the need for bulky adapters or cases. Flip open the cap, connect your device, and SYNC takes care of the alignment- so you're always ready to capture the moment. When not in use, the optic adapter shields the eyepiece from dust and moisture, keeping your glass clean and clear.
