I use a couple of these and like them a lot-
However they need setting up for your eyesight to get the best out of them.
Do you wear glasses and do you take your glasses off or not when you shoot? Whichever you do be consistent and adjust the ocular lens until the image is sharp. You may be surprised (as I was) at how much you need to wind out the ocular lens! But once you get it right then it will be pin sharp at all ranges and what's more the range shown on the objective bell will be pretty close to what you expect.
Good scopes but as I said above need setting up for YOU to work well.
