BALL DATA

Ball Speed
Launch speed of the golf ball. Ball speed has the biggest effect on carrying distance. Centeredness of impact and an increase in club speed will ensure a higher ball speed.

Vertical Launch Angle
The angle at which the golf ball is launched relative to the horizon of the radar. Launch angle will influence the shot height and is mostly determined by the dynamic loft and angle of attack.

Horizontal Launch Angle
The direction in which the golf ball gets launched relative to the radar’s target line. Club face angle will have the biggest effect on the horizontal launch angle of the ball.

Vertical Descent Angle
The angle at which the ball approaches the landing area. A lower descent angle will increase distance with a driver, and a steeper descent angle will give a player more stopping power on the green with an iron.

Smash Factor
Ball Speed / Club Speed
The energy transfer ratio from club to ball as a result of impact position on the club face. The centered impact will improve smash factor for optimal ball speeds.

Spin Rate
A number of rotations per minute of the ball at launch. A higher spin loft and higher friction will increase the spin rate of the ball.

Spin Axis
The axis tilts on the ball to determine the direction of curvature in the ball flight. A function of the delta between the club face angle and club path. The amount of curvature in the ball flight is governed by (ball speed)2 as a result of aerodynamic forces on the ball.


Carry Distance
Landing distance of the ball from the tee. Ball speed, spin rate, spin axis, and vertical launch angle are all factors that will determine the carry distance.


Roll Distance
Amount of roll from carrying distance to the final position of the ball. Lower spin rate and lower effective angle of descent will increase the amount of roll on the surface.


Total Distance
The final position of the ball on the ground from the tee.


Lateral Landing
The distance of the ball’s impact point measured perpendicular to the target line.

Apex Height
The maximum height of the ball trajectory.


Flight Time
Amount of time the ball spends in the air from the time of club impact to initial ground impact, measured in seconds.

Shot Dispersion
Grouping of the landing positions of shots with the selected club showing forward and lateral deviation of that cluster of shots.

CLUB AND SWING DATA

“Played this course for the first time last week, didn’t even know it was there and have lived in the area for years! 27 holes, really well kept course, proper challenge and really beautiful club house too. will def be coming back this summer.”

“Hartsbourne is an excellent golf course with superb facilities, all the staff are very friendly and I highly recommend you pay this hidden gem a visit.”

“From being greeted in the car park on arrival to being served our after dinner coffee and mints all the staff, management and members were friendly, helpful and professional.”

“Fantastic nick, tricky and fast greens, challenging and interesting course. Quiet and peaceful with excellent facilities and friendly staff. A real gem.”

“From the moment we were met in the car park to the sad goodbyes at the end of a great day all of the staff at Hartsbourne made our day and golf play most welcoming. Thank you very much.” SGS Golf Society

“We had a very enjoyable day, the course was superb and everyone was very welcoming...”

“The course is good it is in excellent condition and the greens are very tricky so credit to the greenkeepers and staff.”

“However the facilities are something else. great changing rooms, great food, they go out of their way to make it a great experience from beginning to end.”
