The unique design of this particular pendulum sight enables the incorporation of a scope for magnification of target. This sight also incorporates a locking device which enables the archer to use the unit as a conventional sight for ground level shooting.

Thats a great answer to the what... let me try and take on the how....
Gravity is a constant in all shooting. As soon as your arrow leaves the bowstring, it is being affected by gravity. The farther your arrow travels, the longer gravity has to grab that arrow and make it fall closer to the earth. As one would imagine.... if your target is distant (over 10 yards or so), you need to allow for that drop in order to hit your target.
If you hold a pendulum sight level with the ground and then drop it down below parallel... please note that the sight pin swings outward, but also note that in relation to its previous position, it is also moving UPWARD... meaning that your sight is effectively moving UP. As your range increases, you will need to use more vertical allowence... so a lower pin will make you raise your bow higher to account for this...
With a fixed pin sight, your top pin will be your closest yardage, typically 20 yards. The next pin DOWN will be 30 yards.... it makes you raise the bow HIGHER to account for the longer effect of gravity. When sighting in, you follow the arrow with your pins.... if you are shooting low... move the sight down etc etc.
Hope that is of some help to you.
