So I have been out of the archery game for 8+ years (literally have not looked at anything archery related since then so I am still catching up on lost time with the progression of archery technologies) and really want to get back into it. As I was shopping around for a new bow I came across the Garmin Xero sights. Wow since when did archer become so fancy? But at the same time I am kind of a gear nerd and the concept of it has really intrigued me. I was wondering what are others thoughts are on these? Do they work as well as advertised?
