The HookUpz 2.0 is a universal smartphone digiscoping optics adapter that allows users to connect their smartphones or tablets to a variety of different optics. Then, use your built-in camera applications to take pictures and record video through the eyes of your optics. Connect your smartphone to binoculars, spotting scopes, telescopes, microscopes (including slit lamps), monoculars, endoscopes, borescopes and so much more! The HookUpz 2.0 has glow in the dark rubber pieces to increase visibility in low light situations. The clamping mechanism features a self-centering, dual-spring, quick-release clamp and an optic cam-lock for a tighter grip on your eyepiece to prevent sagging and slippage issues. The horizontal phone alignment is now done using a variable pitch screw for fine control adjustments but can also be moved quickly between iPhone (corner camera) and Android (center camera) positions. The vertical alignment is now controlled on the top for a more compact design that should not interfere with any side buttons on your phone. The HookUpz 2.0 includes a protective EVA zippered storage case along with an optional lens spacer for added eye relief. Limited lifetime warranty.
