I’m a little confused at what a Beiter button does. - eviltoast

I shot compound for probably 10 years, I know a bit of compound archery because my dad is friends with a professional archer.

I never did recurve though and I’m looking at getting into it because it looks more challenging. I have most of the parts I want spec’d out and I see a lot of people recommend getting a Beiter button.

I looked into it and I didn’t really get a direct answer on what does, based off of appearances it looks like it just pushes the arrow where you want it to keep it centered but I’m not 100% sure.
