If the view through your rangefinder is blurry, you may need to make a simple adjustment using the white eyepiece. It rotates so you can adjust it like the lens of a camera or binoculars. To start, turn the eyepiece directly to the middle. The distances and view through the scope should become crystal clear. You can then adjust the eyepiece as needed. If this doesn’t resolve the problem, please contact our customer support team at support@blueteesgolf.com.
