I agree 100% with needing it in broad daylight. “Daytime bright” isn’t really necessary. Where I can see using it is hunting in the timber. I live and hunt in the Pacific Northwest. I don’t know if you have ever done that or not, but it can get very thick and very dark. It is possible to find yourself in holes so deep you start wondering how you’re going to get out. Add to that a good winter storm where it might rain 3 to 6 inches in a day and it can be down right dark in there. In those situations, you’re not going to get a 300 yard shot with time to set up and zoom in. Your shots are going to be, generally, under 50 yards at a critter that just jumped out of its bed and took off running. Needing to acquire that reticle and get it on target in a hurry is very important. Can it be done without illumination? Absolutely. Would illumination help to see the reticle? Also, absolutely. In those situations I would rather have it and not need it. But like I said, I didn’t want to have to rely on it and with the MOA reticle in this H6xi I don’t think I will.
I live in Idaho. So I have definitely hunted in the PNW
