Abstract: PURPOSE:To grasp the correct passing time of a swimmer by always displaying a target time and a passing time at a displaying unit provided at a prescribed position in a pool. CONSTITUTION:A target time is set to the setter in a transmitter 2. For plural displaying units 3 provided at a prescribed position in a pool 1, the target time is displayed by the signal column sent from the transmitter 2 through a first transmitting line 4 by the start of a swimmer. Simultaneously, the passing time from the start is also displayed at the displaying units 3 by the signal column sent from the transmitter 2 through a second transmitting line 5. Consequently, since the swimmer can visually confirm the target time and the passing time simultaneously at the vicinity of the providing position of the displaying units 3, the deviation from the target time can be grasped without receiving the assistance of a cooperator. When the swimmer turns a starting position, the swimmer touches a touch sensor 6, the target time is renewed and the target time and the passing time after the turning can be displayed at the displaying units.
