I don’t have the BX-4 HD but’s have looked through them at Sportsmans. I do have the BX-3 Guide Pro HD in 10x50. I’ve read that internally there isn’t much if anything diffenert between the two. I’m really happy with the BX-3 HD, for the money they are great.
thanks I found a good deal on the bx-4 but cant find much feedback at all, I think im going to give it a shot, my eyes don't really know the difference between good and bad glass yet but I want to get something ill be comfortable using for the next few years atleast.
