I am looking at a few scopes in the sightron lineup (S2 big sky and S3) and I have noticed that they offer a fine plex with a dot. My question is that when you are in the upper magnifications, does the dot take over the entire picture, or are you able to differentiate between target(s) still? This scope will be for target shooting only, with max range of 600 yards for now. Thanks in advance for any input.
