Set up in three steps.
Install on your PC
Install Course Control from the Microsoft Store on your Windows PC. It connects to GSPro and starts with Windows.
Scan the QR code
Open Course Control and scan the QR code on its window with any phone or tablet on your WiFi. There is nothing to install on the phone and no address to type.
Play from the tee
Change clubs, check the heat map, or take a mulligan from your phone.
Controls stay on your own WiFi. Questions? Read the setup guide.
