Capture the action through the eyepiece of your Sportich by Sirui optic with this TS-M2 Mobile Phone Adapter. The adapter fits phones 2.1-3.2 inches wide, with camera lenses up to 5.9" above the bottom of the phone. It clamps onto eyepieces 42 and 44mm in diameter, including the Sportich B1042B rangefinder binoculars and S6080A spotting scopes. A rubber ring inside the eyepiece clamp provides a secure hold and thumbscrews tighten on the phone in the adapter. The interior surface of the adapter is rubber to keep your phone from slipping.
