I use a geometric primciple of right triangles. The stick trick! hold the stick so that the distance from your eye to your hand equals the distance from your hand to the top of the stick. Arm should be horizonal, and stick vertical. Now walk forward or back to line up your hand to the hinge, and the top of the stick to the top of tree. Where you stand is where the top of the tree will fall. I've used it many times, and it never fails.
