In particular, the present invention relates to a distance measuring device using a laser for measuring a distance to a target point of a golf pin or the like in a golf course.

In calculating a golf game, calculating the distance, slope, and height from a golfer to a pin on the fairway or a pin on the green is a decisive factor in winning or losing. Conventionally, the distance display on the fairway and the inclination angle up to the pin were calculated depending on the golfer's experience and sensibility. The accuracy of the distance calculation was poor, and especially in the case of the beginner golfer, there was considerable difficulty in calculating the distance and inclination angle.

In order to solve the above problems, the conventional technology provides the distance between the golfer and the pin through the GPS terminal in which the golf course information is inputted in advance, but it is required to periodically receive the GPS measurement error and the update of the GPS terminal, It is practically impossible to update the position of the pin of the golf course or the data of the new golf course and it is difficult to provide accurate information. In addition, the conventional laser range finder has a disadvantage in that it is stored in a separate case for carrying and is transported, taken out of the case at the time of distance measurement, and stored in the case once the measurement is completed.

Meanwhile, it is needless to say that the laser distance measuring device can be used in various other fields besides for measuring the distance in the golf course.
