The USM-2 Universal Smartphone Adapter from Opticron turns your spotting scope, binocular, or monocular into a powerful telephoto lens for your smartphone's camera. Once the adapter connects your optical instrument to your phone, you will be able to take photos or record videos.

The adapter holds your phone in place with four rubber-covered clamps and connects to the eyepiece with another clamp consisting of three rubber-covered pins. Clamp the phone to the adapter. Then clamp the adapter to your optic. The eyepiece clamp will automatically center the camera lens over your optic. Now, you are ready to digiscope.

The USM-2 is compatible with most smartphones on the market, including those with either single or multiple cameras.

• Rubber-coated clamps will hold securely in place any phone with dimensions up to 8.2" in length and up to 4.3" in width
  

• Use with spotting scopes, binoculars, and monoculars
• Self-centering 3-pin eyepiece clamp will accommodate eyepieces of optics that are 31-55mm in diameter
