RE: shoot ing from stands
You also need to bend your neck, feel the bowstring with your nose...If you don't do this then you are in effect raising your rear "sight" and will shoot over every time...
Do you use a peep??? Do you use a head net??? Sometimes the head net will keep you from feeling the string with your nose...If you don't use a peep, either put one on or put 2 nocks on, about 4 inches above the arrow nock and about a half inch apart...Thenyou can center the pins between these nocks...You might have to work with moving them a little to help center...
Also...Make sure you are wearing a body harness...Many of us just aren't comfortable 20 feet up in a tree...That's why we have a tendency to keep our back close to the tree and just drop our arm and not bend at the waist and get our head down on the string...
Finally...Make sure that your broadheads fly to the same point as your field points...
