When those special moments happen, many of us will reach for our phones to take a picture or video. Just as important as it is to witness such events, it is equally as important to have the right tools to record it. Phone Skope has developed two universal adapters (U1 and U2) that can attach themselves to just about any size of optics. Their technology allows the user to adjust and clamp to the optics of their choice. Once adjusted and aligned, the user will then have to equip the adapter to their Phone Skope case (sold seperately), and just like that you will be ready to capture and record anything your telescope, binoculars, or spotting scope can see.
