It is possible to preview courses from home before you play them. Here is a quick walkthrough of what you will see when previewing from home.
Start a round at a course you want to preview. You will probably see the yardage as "9999" if you are not near the course - this just indicates it's out of range for live round.
The next step is to open up the map view of the course. You can view distances from tee to green and lay ups here.
You can tap any position on the map you would like to measure to. You will be given a measurement from the furthest back tee box and a measurement from the position you tapped to the center of the green. If you have a premium upgrade on your account you will also see Plays Like and club recommendations for these distances.
You can do hole flyover by tapping FLY button and navigate between holes using the arrows in the lower right corner.
