American Hunting Journal September 19th 2007:
As fall aproaches and hunters all over the country are in the woods persuing deer the IBO reminds archery hunters to compensate for hunting from elevated platforms. Researches from Michigan State University have developed a formula for figuring point of aim when elevated. They remind hunters to not only account for the angle of penetration, but also the often overlooked difference in point of impact. Studies have shown that it is much easier for archery hunters to just aim 2 to 3 inches higher for every 15 feet of elevation than it is to concern themselves with shooting form and a consistent anchor point. It has been shown 83% of all wounded and lost whitetail can be attributed to one of two factors.
1) Archers figuring yardage distance from the base of the tree instead of from the arrow tip height.
and
B) Archers not correctly figuring (POI) point of impact compensation correctly.
Since scholastic performance in the U.S is on a steady decline the IBO and MSU formed a joint venture to create an easy to use, easy to carry, "hunter trig sheet" table with diagrams to help hunters score more consistently. Prototypes are being field tested this season and production runs are scheduled for spring of 2008. One prototype version is designed to attatch to the limbs of most bows, while other versions are incorporated in a camoflage arm guard, and a flip down flap which can be installed in the archers hat over the left eye. Early tests show the hat flap type is especially helpful for right handed left eye dominant shooters. (an unforseen but welcomed marketing aid)
Until these become widely available, the IBO urges archers to refresh their trigonometry skills and if necessary take a scientific calculator to the stand with them, and also be mindful that all trees are not at or near 90 degree angle to the ground. They also note that precision rifle hunters should also make angle/yardage corrections for a precise shot.
