I hope that this email finds you well. With your SkyTrak Package you will need to mount the projector approximately 6′ feet away from the screen that you are hitting into. We recommend that you hold up the projector at 6′ feet to ensure a quality image on the screen before permanently mounting just so you don’t have to make any adjustments! If you have any other questions or concerns please let us know. Thank you for choosing Rain or Shine Golf, have a great day!
