First, I am a 12 handicap... so lots of room for improvement. For the last 5 years I have used a leupold rangefinder. Unfortunately, that is no longer functioning and cannot be repaired. Given the advancement and improved accuracy of the apps like the one offered by Swing by Swing I am contemplating going that route. I understand that this utility is limited to front, mid and back yardages where the rangefinder is a precise measurement to the stick... But as my handicap suggests, my yardages vary by 5-10 yards based on the quality of the strike. Have any of you already worked through the pros and cons? Any regrets?
