I just bought the Garmin Approach R10 and I'm already having issues with the distances. It's reading right and left correctly, but the distances are way short on all my shots. I hit my 8 iron around 130-140 and it barely reaches 100 with the Garmin. I've tried the exact recommended distances, different distances, re-installing the app, re-calibrating and everything in between and it's still not reading accurately. Anyone have any ideas other than returning this for my money back?
