I shoot single pin. I sight in my bow at 20 yards and thats where that pin stays for hunting! I do shoot alittle 3D and for fun out to 50 yards so I do have additional markings, but for hunting I just keep it at 20 yards. 20 yards gives me from about 0 to 23 yards I'm right on. If I have a 30 yard shot I aim about 3 1/2" high. I actually aim for the spine or bottom of the spine at 30 yards. When shooting 1 pin you learn very quickly how high to aim for a shot, but most are right on.

Good Luck!
