We provide information that will help you improve your score. [Solution] The golf navigation device 20 is a portable golf watch or the like that uses radio waves from GPS satellites and comprises an acquisition unit 21, a storage unit 24, a calculation unit 23, and a display unit 25. The acquisition unit 21 acquires information indicating the speed of the greens on that day. The storage unit 24 stores reference data that shows the correspondence between the user's swing amplitude and the distance the ball will roll when hit with that swing amplitude, for each green speed. The calculation unit 23 calculates the swing amplitude that the user should use on the greens on that day, according to the distance to the pin, by referring to the storage unit 24 based on the information acquired by the acquisition unit 21. The display unit 25 displays the swing amplitude that the user should use on the greens on that day using a color gradient 25C, based on the result calculated by the calculation unit 23.
