Up front I will say that I have never used one in the field. I have looked at them and listened to others talk about their experience with a pendulum sight. Like anything else there are pros and cons and a person has to decide which fits their style of hunting the best.

There are a good number of hunters (myself included) who hunt more than one type of terrain. From what I am told if a person isn' t hunting on level ground the shot may not hit its mark when shot from a treestand. That alone would eliminate the use of the sight for me.

For those who chase elk around in the fall there are plenty of fixed pin sights that are built rock solid that will fit the bill nicely. Certainly hunting out west the shots can be farther than what we normally experience in the eastern deer woods so a multiple pin or an adjustable pin system is normally preferred.

The older pendulum sights also were labeled by some as noisey when the pin would vibrate in the housing after the shot. I imagine the sight makers have addressed this issue and improved it, but anything that is loose would have a tendency to vibrate therefore the potential for noise would certainly be there.

However as you have enthusiastically pointed out they do work and work well in the proper environment. If it ain' t broke, don' t fix it!
