Ok. I'm an idiot. Guess I don't really need angle compensation unless I'm out hunting in the mountains.
I did some simple calcs and with my tree stand at 15 feet high - or 5 yards and distances up to 50 yards line of sight, equivalent horizontal distance is pretty damn close to the line of sight distance (49.5 yards for 50 yards, 19.37 for 20 yards).
I ain't going to be changing my holdover point for that margin of error so no real point I guess changing the range finder right now.
I'm hunting antelope in Wyoming in in a month and I doubt its going to make a difference there either unless I climb a real big hill to shoot an antelope in a valley.
I guess I will switch over to the 1600-B when it is time to move up as I don't require the angle compensation at bow distances.
Still curious about when this feature got added.
