The visual scene or display is blurry in the Garmin XERO X1i scope, what do I do?

To focus to your exact eyesight, you need to adjust the focus wheel, which is the knurled knob at the eyepiece. The scope features +/- 2 diopters of adjustment. Start at nominal by rotating the diopter ring all the way in, then back it out one complete revolution. From there, experiment with rotating in or out until you reach perfect focus of the display and the visual scene.
