LOL mobow thought it right even though his fingers didn't make his point come across....

Like he said, vertical vs horizontal has no bearing on accuracy from a treestand...you only looking at the dot at the end of the pin, again as he said.

Shooting high: As he stated, the animal appears farther than he actually is by adding the height vs actual distance from tree...in most cases unless extreme heights or elevations on side hill etc.. the distance is usually less than 2 yards if not a mere fraction a yard. Most people shoot high because they've either overestimated the distance or simply didn't keep good form by bending at the waist.

Either way, vertical or horizontal, a pin is a pin is a pin from an elevated stand.
