I hunted with the Keller Pendulum, and don' t remember having any bad experiences with it. I thought it worked great out of a treestand.

When I replaced that bow, I did not transfer the sight because I went with something way too expensive and way to technical which I ended up ebaying off my shelf.

Then I went back to basics with the pins and I am happy with them. Today' s bows are shooting so much faster that one pin will compensate 0-30 yards.
