[VAHUNTER]

i bought a Leupold RX11 . i'm trying to get it set up .
it is set on TBR (true ballistic range) C  now. it also has a bow mode. what should it be set on for tree stand hunting??
the TBR gives you the correct range at any angle

TBR. My dad has that rangefinder and he uses the TBR mode, works good.
