When you go out to the round,The part where you use the most strokes is putting. Are you perhaps doing this important putting roughlyby estimation?

Golf gets harder as you get closer to the hole.Putting based on intuition leads to failure inevitably.





Swing distance prediction and correction is
only possible with the deviceGreen Master
.

Judging swing distance is hard to grasp physically even if you know it in your head. Green Master predicts it with astonishing precision. The high-performance gyroscope sensoranalyzes your swingand calculates the expected putting distance.

Green Master goes beyond simple measurement. Through the swing analysis system,you can identify not only the predicted distance but also the swing path, wrist bending, and more. We do.

Unstable putting.Accurately identify what the problem is. Only then can your decision-making improve in practice and real games.

IdealDifference between swing path and actual swing can be checked and corrected immediately. Also,By identifying wrist bending, it helps you maintain the wrist angle as much as possible. It helps you maintain it.


Green'sSlope in all directions, distance to the hole cup, and green speed are considered to predict accurate putting.

Just hold up the Green Master and point it at the hole cup.Calculates the exact distance based on the height of the flag. We do.

Measurement of front-back and left-right slope based onEven calculates the hitting ratio and aiming point so you can easily plan your putting.
Assuming the distance from the ball to the hole cup is 10m, if the hitting ratio according to the slope is <0.4>, the appropriate swing strength is4m multiplied by the shot ratio to the distance to the hole cup. It is.
Assuming a slope of 1% slice, from the measurement position, use the center of the cup as a reference,Raise one finger to the left and extend it to determine the point.
Before useSet the flag height and green speed value to expect even more accurate measurements.

Maker introduction

Our company has been manufacturing branded golf bags for over 20 years, launching and producing golf bags that pursue user experience and design for golfers. In particular, in 2008, we received much love from female golfers by adding wheels to women's caddie bags under the Teddy Bear golf brand, providing convenience and design. The brand for this new launch is Green Master. Many amateur golfers lose their scores on the green. We created the Green Master brand so that at least in putting, you can have pride as a master.
Reason for product development
Many amateur golfers easily lose their golf handicap on the green due to tension and poor distance control, resulting in three or four putts. While putting may seem easy, it can also be the most difficult. We designed this product to help improve putting skills more easily through practice.
Reason for pre-order and plan for using the funds
By succeeding in the pre-order, we can create conditions to more easily enter general domestic distribution. The funds from the successful pre-order will be used to plan the second Green Master and develop an upgraded product. Based on the success of the pre-order, we aim to gain recognition from golfers in the domestic market.

FAQ
1. When measuring slope, if 'Out of measurement range' is displayed
a. The main unit is open. Please close it.
b. This may also be displayed if the slope is too steep.
2. We recommend measuring the exact green speed if you do not want to set or modify the actual green speed. However, if you find measuring bothersome, remembering the points below may be helpful..
a. Since many golf courses have a green speed of 2.6m~2.8m, if you set the green speed to 2.8m, the error in the predicted distance will be within ±5%, so there is no effect.
b. Home practice mats are generally about 3.7m.
3. When the hitting distance and the predicted distance of the practice swing are different.
a. When the green is uneven and accurate prediction is not possible.
b. When you are nervous during the shot and it differs from the practice swing.
c. When the hitting point of the head is off-center.
d. When the calculation of the hitting force measured on an uphill/downhill slope is incorrect.
4. When the result of the predicted distance does not come out with a stable practice swing.
a. Practice frequently at home.
b. Practice swinging like a pendulum, aiming to get close to the yellow and green lines.
c. When practicing swings, your arms should not bend. To check, the red line should be as straight as possible.
5. After hitting the ball on the advice screen, if the displayed distance is different, the distance is only shown for the practice swing, so the distance of the putted ball cannot be predicted. If a distance is displayed, please ignore it.
7. When you hold the main unit by hand, the advice screen is not displayed and the slope measurement screen appears. If you place the main unit horizontally, the advice screen will be displayed.
8. If the screen freezes or operation is not possible, the power will automatically turn off after 30 seconds. Please turn the power on again to use it.
9. In the case of inappropriate (unique) swings, accurate prediction is not possible.
