Abstract: The invention is a training device marker for target shooting. The device contains a semi-rigid support having a forward side, a back side and a flexible material cover stretched over the forward side of the semi-rigid support. The forward side has a first marking and the back side has an affixing means for attaching the semi-rigid support to an existing target. The flexible material cover has a second marking such that when the flexible material is penetrated by a projectile, the flexible material tears away from the semi-rigid support exposing the first marking. The partial or complete removal of the flexible material cover alerts the shooter that the marker has been hit. This has the advantage of being able to be observed at a distance, and with multiple training device markers affixed on a target, the user does not have to stop and confirm a hit after each shot.

Abstract: A golf green is enhanced by sliding a spacer tube and bell onto and circumscribing a flag pole. The spacer tube upper end suspends the bell above the golf green, defining a gap smaller than golf ball diameter. The bell rings when struck by the golf ball. The spacer tube and flag pole reliably locate the bell relative to the green. In some embodiments, the bell is positioned relative to a cup within the hole in the green, while in other embodiments the bell is positioned relative to the green surface. A method of installing a golf bell onto a flag pole having a flag includes disabling a flag on the flag pole, such as by removal of the flag from the pole, slipping a spacer tube about and down the flag pole, followed by a bell until the bell rests on the spacer tube. The flag is subsequently re-enabled.
