about I think I have ten of them dating back 40 years ago. I have about every variable hunting product up to the LPS. I frankly do not even know how to compare or rank them. If the rifle they are on groups well, I leave it alone. There is one 4X12 that has finer cross hairs that I do not prefer, but other than that, they suit me just fine. Most are 3X9, 3.5X10, or 4X12. One is 2.5X8 and one is 1-4. Counting a pistol scope maybe there are 12.
Like a Timex, they take a licking and keep on ticking.
