In this video, Lancaster Archery Supply TechXpert P.J. Reilly takes a look at peep sights for bowhunting.Reilly discusses the purpose and function of the peep sight as it pertains to correctly lining up the archer with his or her bowsight. Some bowhunters prefer not to use a peep, either because it doesn't allow enough light to get to the eye, or because it can cause confusion at the moment of truth. Absent a peep, bowhunters must find a way to consistently anchor and take aim, to make sure they are looking through the sight the same way every time. If there's any change from shot to shot, accuracy will suffer. Reilly suggests a solution for these archers.The peep sight is an easy way to line up a hunter's eye with the sight on every shot. Since it's tied into the bowstring, it forces the hunter's eye to the same point every time the bow is drawn.Peeps come in different sizes, and it's important to note that smaller peeps tend to allow for more precise aiming, but they also allow less light to reach an archer's eye. When that happens, it's difficult to see beyond the peep.In bowhunting, the low light times of early morning and late evening often are the best for deer activity, and so archers may want to employ a larger peep to make sure sufficient light is reaching their eyes so they can see the target at the critical moment.
