I left mine px'd for 25yds and find it's blind between 25 and 20, but that's where the trajectory's pretty flat anyway. Comes down to 11yds at full mag, then wind the mag down between 11 and 8. When it's reparallaxed to 17yds min it can seem that you can't get a full 55- although some say it will re-px to between 65 and 17. My eyes must be shot
I find it easier to use than the Elite 4200, especially with a Jon Harris sidewheel. Big gaps up to 55yds, and nicely compact.
