The R50 desperately needs a feature that lets you offset the center point on an external display, allowing you to hit balls from not just into the center of a screen. For example with my setup I only have space to hit into the right half of the screen, meaning I have to aim 30 yards right of the "target" if i want it to go straight, often leading to pulls by trying to aim for the target line on the screen.
This is a feature on GSPro, Trackman & Foresight Sports
And no aiming the garmin at the center of the screen and hitting at the center of it doesn't work because the image on the display is still aimed "straight"
