Thread: Duplex reticles

Hi members
This may sound like a rookie question but here goes
How do you use duplex reticles for hold over at longer ranges. Personally I prefer reticles with holdovers to allow versatility for quick shots at longer ranges.(300 to 400m)
I'm a quite an european optics fanboy but most come predominately with duplex reticles. My VX5 firedot is same scenario. Yes you can dial but don't like slugging exposed turrets through scrub,also it takes precious seconds on a quick shot.
Anything I'm missing here except for guestimating?
