I use a similar device for digiscoping and find it indispencable. A wire with a screw at one end and bead at the other end. When I get in an area I intend to work I screw the sight into a retainer held to the scopes shade with a rubber band. I wear trifocals and sight over the extend-a-view to locate then move my eye down to focus. A great time saver to allow more time for focusing.
