Golf swing measurement device and golf swing measurement system

A golf swing measurement device for measuring a swing path of a club head with a permanent magnet on a distal thereof, comprising:

• a housing having a sidewall portion extending substantially in parallel to the swing path;
• a first sensor coil disposed along the sidewall portion for detecting the club head passing therethrough;
• a second sensor coil disposed along the sidewall portion at a front position of the swing path with respect to the first sensor coil by a specific distance for detecting the club head passing therethrough;
• a calculation unit for calculating a swing time from a start moment of a backswing to a moment of an impact, a head speed upon the impact, and a total flying distance according to a detection signal of the first sensor coil and the second sensor coil;
• a display unit for displaying the swing time, the head speed, and the total flying distance;
• a memory unit for storing measurement data including the swing time, head speed, and the total flying distance;
• and
• a transmission unit for sending the measurement data stored in the memory unit externally.
