George,
The One Miles don't have the blue-green tint that the 1600's displayed. They are indeed a second generation. They're a long ways from my Leica's optically still!
My brand new 1 Mile Fusions just came, and as you have stated they do not have the blue/green tint to them like my 1600's did, either.
In casual "testing" here in my neihborhood, the glass seems to be pretty good, I plan to take them with me to our deer hunting area on Tuesday and give them some field use where I actually hunt.
Jury is still out as to whether I keep them or sell them. Keep is in the lead because I do not have the bucks to upgrade, and when a big game animal is on the move, there is often (IME) not time enough to use a binoc and then grab and use the rangefinder. Where others hunt this may not be the case, but there is enough hunting pressure on deer out here that oft times when I have seen a good buck he is already 350 or more yards out and trotting AWAY. Getting the range RIGHT NOW and getting a shot can men a shot within my makeable range vs not or too far for me to feel comfortable with a try.
Sitting and watching for a bear where I hunt, you only have Mr. Bear (who will also be moving at a good clip, just because that is what bears DO when travelling form one foood source to another) in a small opening through the trees and shrubs for a very brief time so getting a good look and getting a range on him has to also be done very quickly.
I have NO doubt that having a binoc/LRF combo has made the difference for me on a couple of animal's I have killed in recent years. Others hunting areas or style may not be so time critical, and two sets of optics might work just fine.
More testing of this unit and reports, is needed. Thank you for the reports given so far! MARK
