A device for retrieving and positioning of golfing articles, such as a golf ball and tee, to eliminate the repeated bending down of the golfer. A peripheral face extends between the opposed faces and has first and second opposed sides and first and second opposed ends. Dip is calculated in the first direction from the horizontal gradient in the first direction and the vertical gradient. The protrusion 4 is brought into elastic contact with a large-diameter cylindrical surface 23 formed on the outer race 21. The reference point defines a measurement plane perpendicular to the shank axis. An irregularity measure is determined based on the regions intrinsic characteristics rather than on the shape of the pixels within the region.
