PROBLEM TO BE SOLVED: To surely detect landing to a target and quickly output a result of shooting such as number of landing and hit probability in a target practice device. SOLUTION: In a target practice system composed of a target device 2 and a control device 4 as shown in Fig. 4, the control device 2 presents and conceals a target 21 on the basis of target presenting/concealing instruction command. The landing to the target is determined on the basis of whether the landing exists or not on the basis of frequency components of an impact shock sensor, and the number of landing is counted. The control device 4 receives a result of counting of the number of landing transmitted from the target device 2, calculates evaluation data such as hit probability, and displays a result of shooting practice.
