You get what you pay for mostly. When were getting ready for 1st out west hunt i bought a redfield and thought i was good to go . [not] . When i was looking at antelope and trying to judge between 14" and 14 1/2 or 13 3/4 at 500-600 yards it was tough. As luck would have it the rancher let us use his leupold goldring. 15x48 [i think it was]
anyway it made a big difference and i am saving my $ for a quality piece of glass.
