Abstract: A target includes a sheet of a material, the sheet includes an uprange-facing surface, a downrange-facing surface, an upper end, a lower end, and opposed sides each formed with an origami structure. Each origami structure is a partially cut-out and foldable structure formed in the material of the sheet being foldable from an unfolded condition to a folded condition. Each origami structure is flattened in a direction toward the downrange-facing surface of the sheet, when in the unfolded condition, and forms a sleeve structure deployed rearwardly from the downrange-facing surface of the sheet that is adapted to receive a support pole therein for retaining the sheet to the support pole, when in the folded condition.

Abstract: A gauge for measuring the relative resiliency of golf greens including a barrel shaped device with a base having foot pads to hold the instrument on the green and a calibrated spring to drive a measuring tip into the turf and a scale indicator attached to the barrel for providing the information indicative of the condition of the green.
