Senses combined can create a map of the surrounding area, let alone find one target. Combine everything you hear, smell, feel and taste and heighten the sensitvity and you can aim a bow at the target because you now it's there. The material they make their equipment out of is Chaurus, which is an animal which I can imagine gives off some odour. Also the Falmer have hands, which can feel things around them, like cliffs.
