I have a buddy that just bought a new pair of hd-b's and he can not get them to range past 400 yards, any one have an idea of what the problem could be. thanks for any help
I just received mine a couple weeks ago and I can hit WAY out there free hand. I've had them on a tripod mostly and cedar trees are easily point and shoot to over 2000 yards. I'd throw a battery in them and see what they do. If not there's a problem for sure.
