Magview S1 Features The Magview S1 binocular adapter uses rare earth magnets built directly into its housing to create a fast secure connection with the companion phone plate. Sized for eyepiece diameters between 44mm and 48mm the B1 XL version slips over the eyecup and is held in place with a simple retaining screw rather than a bulky clamp. This set it and forget it design does not impede the normal use of the binocular so the adapter can stay mounted between digiscoping sessions. Finished in matte black and built from polymer the adapter adds minimal weight at 0.6 pounds shipping weight. Each S1 kit includes one Magview Phone Plate so the system works right out of the box once the plate is attached to the back of a phone. Together the two pieces create a light fast digiscoping platform that lets outdoor photographers capture steady footage at a distance instead of choosing between filming and watching. The plate s magnets do the connecting work so the binocular adapter itself carries no moving parts to fail in the field. Made in the USA the Magview S1 is not compatible with wireless phone chargers a deliberate tradeoff for its slim reliable design.
