HOW FAR UP IN A TREE DO YOU PLAN ON BEING? UNLESS YOU PLAN ON EXCEEDING 25 FEET YOU REALLY DON'T HAVE THAT MUCH CHANGE IN YOUR SHOT DUE TO ELEVATION. IF YOU DO IT MIGHT ONLY BE A COUPLE OF INCHES LOW TO COMPENSATE. BUT DEFINATELY DO WHAT OTHERS HERE HAVE SAID, GET OUT ON STAND AND SHOOT AT TARGETS AT VARIOUS DISTANCES TO SEE WHAT THE ELEVATION DOES TO YOUR SHOT.
