I shot a pendilum for a couple of years a long time ago ! And I don't see anything wrong with them......the old ones were noisy.....but I don't think the newer ones are supposed to be !

Now a days .....with the speeds of the new bows..... I just see no need for one ! But that is a personal preference !

I can easily shoot to 30 yrds with a 20 yrd pin with very little adjustment !
