PURPOSE: A screen golf training apparatus using a dual sensor is provided to improve reality of golf training and to facilitate the appropriate golf training by precisely determining the trajectory of a golf ball. CONSTITUTION: A screen golf training apparatus(100) using a dual sensor comprises a free sensor(110), a main sensor(120), and a controlling unit. The free sensor and the main sensor are located between the impact position of a ball shot by a golfer and a golf screen in order. The control unit calculates the trajectory of the ball by referring to the location of the ball which is detected by the free sensor and the main sensor. The controlling unit determines the actual shot speed of the ball by time the ball passes through between the free sensor and the main sensor.
