<p>PROBLEM TO BE SOLVED: To stimulate the imagination of a player himself by pouring a liquid and a bubble in a ball mark used for golf so as to roughly predict inclination, etc., on green. SOLUTION: A transparent and horizontal upper lid 1 and a recessed bottom face 2 are overlapped and the liquid 3 and the bubble 4 are poured in it. Characters 5 such as slice, hook, up, down showing a direction and an arrow 6 are written on the surface of the lid 1. Then the mark is used similarly to a conventional marker on the dropping spot of a ball on the green by turning the arrow toward a cup. The direction of slice, hook, up, down, etc., is read by the moving of the bubble 4 moved by inclination in the liquid 3.</p> |
