Abstract
A customizable alignment sighting device for a golf club is mounted to an upper surface of the head of the golf club with a sighting element providing the user a visual target indicator for desired alignment of the club head with the user's line of sight. The sighting element can be readily adjusted for the user's preferences. When not aligned, the sighting element provides an indication of the magnitude and direction of misalignment.

The sighting element is a concave lens or lenticulated grid or grill superimposed on a target image. In another embodiment, the device has a 3D device body mounted in a mounting cup or socket fastened to or formed in the head of the golf club. The device body has a larger-diameter circle marked around an annular opening, and a smaller-diameter circle marked depthwise inside the opening in the device body to provide a target of concentric circles by parallax effect. The device body can be formed as a sphere with axially split sides that are expanded outward when an expansion plug is threaded in the bottom…
