There are alot of pendulum sights out there, I use to own the Keller, if you sight in from 15 feet up at a 20 yard target, you will be on from right under your stand out to 40 yds or more if you choose. With todays high speed bows there really isn't a need for a pendulum sight. Pendulums came out when a FAST bow was shooting 230 to 240 FPS. Todays bows far exceed this. If you are shooting a fairly new bow with speeds in excess of 250FPS, I would recommend staying with your regular sight.
