I have only used the app and rangefinder twice now, so this could just be user issues. The actual distance on the rangefinder is a little hard to read where placed on the screen and I tend to hit objects behind the flag more often than the actual flag. The app is not as good at 18Birdies as far as hole detail on the overall layout. I do really like th AI Caddie feature and hope the app catches up to 18Birdies.
