It's just a second aim point. So it allows you to bracket known sized objects to determine distance. There's a bunch of extra turrets it comes with that include ballistic drops of rounds (from memory) so you essentially bracket and dial it in and it's on zero... in theory.
Not sure how it works with .177, but it's a bit of 80's holdover tech to play with
