[QUOTE="jmden, post: 372507, member: 1742"] I wonder what is meant by 'declination' here. Declination, as I'm guessing most of us use it, (same thing as 'variation' in mariner jargon if you are navigating on water) is the angle difference between true north and magnetic north when using a compass. But here I get the impression they are using it to describe downward angle and 'elevation' as up angle. Or, or they mean 'compass bearing' that would be used in dealing with coriolis effect? This really starts to beg the question of how sophisticated is the ballistic software? Will it deal with coriolis (have my doubts on that one), G7, spin drift? It must allow user inputs regarding the ballistic properties of your bullet and load, wouldn't it? I hope that if Leica is getting into ballistic programs with this unit, that they don't 'half-a_ _' it, but use a powerful program. When you are shooting distances like this thing might be able to read to, inputs like G7 capability, coriolis and spindrift become more important. I also hope that they use a similar beam shape as the other Leica's but tighten up it's divergence. I think if many of us designed these things, that's what we would want to do. It'll be very interesting to see how this unit stacks up against others currently in the field and some others that have recently been mentioned on lrh.com that should be coming on the market in the not too distant future.
