Kowa, together with the well-known mobile accessory manufacturer Otterbox, has developed a series of high-quality cases that fit the latest, current generations of iPhones and Androids from Samsung.
The shells are made of a rubber-plastic mixture and provide good protection for your mobile. On the back of the shell (camera side) there is an opening for the optics and a thread where the appropriate ring for your eyepiece is screwed on. It couldn't be simpler! Rings are purchased as a separate part and are, of course, primarily adapted for Kowa's range of spotting scopes and binoculars. But a lot of other fabrics also works with these rings. Together with an adapter, you can use the shell with rings from Swarovski and Zeiss.
