The Square-Up provides the shooter a real time reference in his sight picture to recognize and correct his/her riser torque before the shot. The ability to see the bows torque and square the riser to the sweet spot on the center position will make every shooter more consistent and in most cases will result in dramatic increase in effective range. The increase in accuracy will instill confidence and will result in more, well placed shots, shorter blood trails and more recovered game. It will also answer some of the nagging thoughts and questions we have as bow hunters regarding those blown shot opportunities of the past. Bow riser torque is the most common shooting error and until you have the ability to see it and correct it; it is a phantom that will haunt us and usually at the most inopportune times. This product will work for every bow and arrow set up. Also you will find that the product is simple and effective even in low light situations. We like shooting with our peep sights so we designed a product that works with the peep but experience teaches us that Square-Up works just as well without the peep sight.
