need help sighting bow in
Hello everyone. I just bought my wife a new mathews passion to replace her old bow. Now we have run into a problem. the first shot she took at 10 yds to start sighting it in. The arrow hit low. No problem, arrow needs to go up, sight goes down. Next arrow hit low still so i move the sight down again. Long story short. The sight is pretty much bottomed out and arrows are still hitting low. I nocked an arrow and elevated the drop away rest and checked it with a T square and the arrow is perfectly flat. I dont know what else to do. Any suggestions? Thanks
