Abstract: Provided is a sensitive golf club with a sensor unit. The sensor unit includes a battery, a sensor module configured to measure sensor data indicating a state of the golf club using power from the battery, a communications unit configured to wirelessly transmit the sensor data to an external device using power from the battery, and a control unit configured to control operation of the sensor module and the communications unit using power from the battery. The sensor unit has an A mode, and a B mode in which operation of the communications unit is suppressed compared to the A mode. The control unit is configured to judge whether or not the golf club is prepared for a shot based on the sensor data, and switch between the A mode and B mode based on whether or not the golf club is prepared for a shot.
