Gradient-gauge applicable on golf green

Abstract

A gradient-gauge applicable on golf green comprises a main body and a bulb level. The main body made of a transparent material is provided thereon a pair of horizontal line and perpendicular line, and its one side is parallel with a straight edge of the horizontal line. A pointer is pivotally jointed at the intersection of the horizontal line and the perpendicular line. The bulb level, which is disposed on the main body, is curved and drawn with angle graduations, in which the bulb of the bulb level is in a position corresponding to the perpendicular line in case the main body is laid in a horizontal plane.

1 . A gradient-gauge applicable on golf green, comprising: 
 A main body made of a transparent material, on which a pair of intersected horizontal line and perpendicular line is marked; and    A bulb level, which is disposed on the main body, being curved and drawn with angle graduations, wherein the bulb of the bulb level is in a position corresponding to the perpendicular line in case the main body is laid in a horizontal plane.    
   
   
       2 . The gradient-gauge as claimed in  claim 1 , wherein a pointer is pivotally arranged at the intersection of the horizontal line and the perpendicular line, and directed to the bulb level.  
   
   
       3 . The gradient-gauge as claimed in  claim 1 , wherein a straight edge parallel with the horizontal line is formed on one side of the main body.
