Why are the numbers on golf balls red and black?
Why are the numbers on golf balls red and black? The color of the golf balls being black or red go back to when golf balls were truly made to compression ratings. Red numbers used to represent 90 compression balls, and black numbers were to represent 100 compression balls.
How do you determine a golf ball's flight?
The ball's flight will then curve to the right or 'Slice'. Hitting the ball with a closed club-face and a club-path from in to out will cause the ball to spin from right to left. The ball's flight will then curve to the left or 'Hook'. Golf ball flight trajectory traces in the GSA Golf system.
What does X and y mean in a golf simulation?
After every time step the simulation will be recalculated. 'x' is the coordinate in the direction of the range. 'y' is the coordinate in the direction of the height. When the clubface collides with the ball it's total contact time is approximately 0.0005 seconds and the peak force applied to the ball can be as high as 4000 pounds
What is a good golf ball flight?
Good: Such a ball flight is deemed to be desirable because the ball will land near the intended target. A golf ball that draws will begin to travel outside of the target line before coming back towards the target.
What do SkyTrak numbers mean?
Skytrak directly measures ball speed, back spin, launch angle, side spin and side angle. These parameters are modelled to calculate accurate approximations of further data including carry, roll and total distance, clubhead speed and angle of descent.

What is the best lighting for SkyTrak?
To maximize the chances of Skytrak reading your shots, you need a well-lit ball but not too much light on the lens itself. Of course, you need to balance this against having a washed-out image on your impact screen and optimizing the immersive experience of your simulator.
What is PTI score on SkyTrak?
SkyTrak software provides Power Transfer Index (PTI) or what is commonly known as Smash Factor. Smash Factor is ball speed divided by club speed. Smash Factor relates to the amount of energy transferred from the club head to the golf ball. The higher the smash factor the better the energy transfer.
Are SkyTrak distances accurate?
SkyTrak's photometric technology has one main downside but overall is extremely accurate and reliable. From our experience, SkyTrak's data is remarkably almost always spot on, and usually not more than 1-2% off from the more expensive units such as the Foresight Sports GC2 or FlightScope X3.
What do launch monitor numbers mean?
Significance: If the number that shows on your launch monitor's display is positive, the golf ball will end up to the right of your target. If the number is negative, the golf ball will end up left of the target. Use the side angle numbers to help you focus on your swing path.
What is a good launch angle for irons?
A golfer on the PGA Tour will have a launch angle of around 15 degrees for their seven iron. Those on the LPGA Tour will have a slightly higher angle at around 20 degrees. Most average golfers will fall somewhere around the 22-degree mark, but it all depends on the player's club head speed.
What is ideal driver launch angle?
The ideal launch angle for a driver is between 15° and 17°. This is NOT the same as loft. Launch is defined as the angle between the ground and the ball flight just after impact, and is the result of the clubs loft and attack angle.
Does SkyTrak work in dark?
You need to have enough light to see and swing the club, but not too much direct light shining on the Skytrak camera lens. This means Skytrak can work in a wide variety of lighting conditions and doesn't mean your golf simulator room needs to be super dark.
How far should a screen be from a golf simulator?
Your impact screen should be 12-16” away from the wall behind it. Then, it's a best practice to place your tee 10-15' away from the impact screen. Lastly, make sure you have enough room behind the tee to swing easily. In total, that's at least 15' deep is ideal for a golf simulator room.
Does SkyTrak show club speed?
SkyTrak is a camera-based launch monitor and generates high-speed images to track things like ball speed, spin rate, and launch angle. With this data the software is then able to accurately provide other data points such as carry/total distance, roll, offline, flight path, club head speed, and angle of descent.
Why is a ball flight considered desirable?
Good: Such a ball flight is deemed to be desirable because the ball will land near the intended target.
Where does a golf ball go when it travels along a pulled hook flight path?
A ball that travels along a pulled hook flight path will start to the inside of the target line and will proceed with curling aggressively to the inside still, before coming to rest way left of the target (for right handed golfers).
What is a ball that travels along a hook flight path?
A ball that travels along a hook flight path is one that will start to the outside of the target line before curling aggressively towards the target and passing it before finally coming to rest to the left of it. Balls hit in such a way will carry a lot of topspin and as a result will roll a considerable distance after landing before coming to rest.
Why is it desirable for a golf ball to fade?
Good: Such a ball flight is deemed to be desirable because the ball will eventually land near the intended target.
Why is a pulled ball undesirable?
Mediocre: A pulled ball is deemed undesirable because the ball will miss the intended target, landing left of it instead. Opposite: The opposite of a pull is a push. More on: How to Fix a Pull.
What is a straight shot in golf?
Straight. A golf ball hit straight will travel directly in line with the target, from the moment it is struck all the way to the moment when it lands. A perfectly straight shot will not veer sideways at all and the amount of roll upon landing will be determined by the club selected. For example, a ball hit with a 9-iron will roll less ...
What does a power draw look like?
Traveling along an aggressive outside-in flight path, the power draw’s shape will resemble that of a hook with the important difference that it will land near the intended target. As such, it is still deemed to be desirable when executed on purpose, in order to clear troublesome areas, for example.
How to calculate velocity of a golf ball?
The equation 5/7 f v sin 0 is used to calculate the vertical velocity of the ball traveling up the club head face where f is the fraction of speed remaining when the compression of the ball is considered, 0 is the angle of the clubface at impact and v is the velocity of the club head.
What happens when you top the ball in golf?
Topping the ball (i.e.. when the bottom of the club-face hits the ball above its center) will cause the ball to spin in the other direction - i.e.. downward - which will cause the ball to dive into the ground. With really high spin rates the magnus lifting effect will actually increase the ball's rate of climb.
What is the pushing and lifting effect of a golf ball?
This pushing and lifting effect is dependent on the top-spin rate of the ball. When the ball is struck properly by a lofted club, the ball will tend to travel or roll up the club-face before it is launched. This causes the ball to anti-clockwise spin at a rate governed by the speed, loft and surface friction of the club head face at impact. Typical ball spin-rates are:
How to find the spin axis of a ball?
i.e. we just have to measure the center of rotation offset to the center of the ball and apply this to some simple trigonometric math to determine the spin axis.
What causes a golf ball to spin?
Hitting the ball with a closed club-face and a club-path from in to out will cause the ball to spin from right to left. The ball's flight will then curve to the left or 'Hook'.
Why do golf balls have dimples?
As you probably already know, the dimples on the golf ball are there to give the ball more lift and reduced drag during its flight and therefore increase its carry through the air.
How fast does a golf ball fall?
Due to air resistance a falling golf ball will not continue on accelerating at the rate of 9.8 meters / per second / per second. It will eventually reach a maximum falling velocity dictated by its mass and area. This velocity is known as Terminal Velocity and in the case of a golf ball with a radius of 2.1 cm, an area of 14cm² and a mass of 46 grams, this will be 32 meters per second or 72 mph.
What does the green light on a GC2 mean?
Once the GC2 is locked onto a ball, the "ball-lock" light will turn solid green, indicating the ball may now be struck.
What happens when you lock a ball and not connect to a computer?
When locked on a ball and NOT connected to a Windows computer, the previous shot data will appear on the LCD screen.
How to connect GC2 to Foresight app?
Open the Foresight Sports Performance app. Locate the GC2 device you wish to connect to and press and hold until “CONNECT” appears. NOTE: Connection times vary by device.
How to pair GC2?
While the GC2 is turned on, locate the SERIAL NUMBER of the device (located on the label underneath). Select the device with that SERIAL NUMBER to pair with it. If prompted for a code, enter four zeros (0000).
What does solid green mean?
SOLID GREEN: indicates the ball is recognized and the device is ready to be used.
Does the GC2 display flight information?
The GC2 does not display some (or any) ball flight information: Test the device with a new flash module (or one you are certain is functioning). This will help determine if the flash module is the true cause of the issue. If the flash module is working correctly, please see "Ball Finding & Missed Shots" below.
