I really like the Leica HD-B series sensors and the programmable Micro SD card using your rifle's exact muzzle velocity with a specific ammo - not something ballpark from a "ballistic library".
BUT... to get a TRUE ballistic firing solution you must, of course, have the wind input. And I am waiting for the HD-B binoculars to have Bluetooth capability to send/ receive information to and from my Kestrel 5700.
With the pace or advancement in electro-optics we will see it soon in binoculars and not just on the expensive Vectronix monocular LRFs.
