83mm long plastic golf tees with cushion top. Multi-colored and durable. Wonderful equipment for golf lovers.The most important technical parameters for evaluating the performance of the ball are: the inclination of the bar surface and the angle of the floor. Proper landing angle helps to swing continuously. The difference between the landing angles will cause the ball to be right or left. The inclination of the bar surface is equally important. It is common that the difference between supports is 3 to 5 degrees in each set of clubs. For example, if your 5 is slightly inclined and the sixth is larger, the distance between shots may be the same. When the ball club concentrates on the root, turf or other hard things, it may affect the inclination and landing angle of the bar surface. Because of the strong technical, it is better to get the maintenance shop for inspection.There are many reasons for rod surface wear. If the center of the rod surface is severely worn, it means that the ball is frequently hit. If there is a problem with the root and toe of the head, it suggests that there is a problem with the swing or the club assembly. Toe wear indicates that the rod is too short or the player is too far away from the ball. The root wear indicates the opposite. The wear of the bottom of the rod can reveal the problem of landing angle or swing. Under normal conditions, wear occurs in the middle of the bottom of the rod, i.e. under the sweet spot. If wear occurs at the root, it means that the landing angle is too large or the grip position is too low. Hitting with the root can easily cause the left curl. On the contrary, if the abrasion occurs at the toe, it means that the landing angle is too small or the grip position is too low and the swing is too steep. Hitting a ball with your toes can easily cause a right curl. If you have any of these questions, it is best to consult with a professional to correct the club or stroke position.
