yea they are neat, the only reason i changed about 10-12 years ago was because the guys we hunt with in canada recomended that we practice out to 50yds, other than the distance i always loved mine also, i've got an older high country i sticking it on, seems like i bought this thing 20 something years ago got the video, set it up as per the video, and i was amazed.....like i said it brought back some good memories. the only thing i didn't like was a deer uphill from me if you know what i mean............
