Used it at 100 and 200 yds at the range and had no problem seeing 243 bullet holes. In the field looking for trophy goats it was very effective at about 600-700 yards. Only weakness is the tripod it came with. That said i also bought the Alpen micro adjustable benchtop tripod which was great when scanning several targets at the range. However, even the Alpen like the free tripod was a bit shaky like the at higher magnification. It was difficult to use even the fine focus on the scope as the image was being shaken too much by the touch of the adjusting finger - all due to the tripod not being solid enough.
Pros: Very clear glass. No edge distortion
