I did not find the deer and the crossbow has an adjutment on the side of it to set it at 0 for sighting at ten yards and then it automatically adjustes when you turn the knob. It gose up to 90 yards so I set it to 7 for 70 yards the deer did not move fast when I shot they stayed there untill the arrow hit something and then they just ran a couple of yards and stopped again and then finally ran off but I could not see if I hit one and it went running wild they were in a thick brush after I shot
