[QUOTE="catorres1, post: 1471270, member: 80699"] I got to play with a pre-pro set of these and have gotten a fair amount of info from a guy I know at Sig, but I don't have one to test, so take this for what it's worth. I assume you are familiar with the ABS, so I won't go into that...the BDX line's main selling points are: all the RF's have ABS ultralite loaded on. What that means is that out to 800 yards, it will provide a shooting solution from the custom curve you load for your rifle. However, unlike the full AB on the ABS, it does not take into account higher level forces like Coriolis, Aero jump, spin drift etc....it really operates much like the ballistics on a Leica 2700. And like the Leica, they limit the return due to those limitations. Second, they pair with the BDX line of scopes and your holdover etc. is displayed via a highlighted dot, it also has electronic cant indicators. At this time, the BDX line of scopes is on their lower end. They plan to eventually expand the offerings to their higher end scopes, but for the moment, they said they wanted to roll it out at a level where more shooters could afford the system. To me, the real advance comes only in the 2400 BDX and/or the 3000 BDX (bino model). These two models include all the previous capabilities, but where they shine is that they will connect direct to a Kestrel running the full AB solver. So like the new Vectronix x, you range, and it dumps all the info to your kestrel, where the full AB suite crunches the numbers.

There are some upsides to that but also some downsides, particularly in temps and wind handling, though the second is arguable.
