I hope that this email finds you well, thank you for reaching out to Rain or Shine Golf. It depends on which screen you are using for the distance from the screen for projector, for the majority of our screens you will be in the 6′ to 8′ feet range. We recommend that the projector is close to the top frame of the screen you are hitting into. Which impact screen were you interested in?
I look forward to hearing from you soon, have a great day!
