SIG Sierra 3 BDX 4.5-14x44 riflescope is capable of Bluetooth interaction with cellphones (with app) and with Kilo style SIG range finders. This allows the shooter to set their dope on their Bluetooth devices pair it with the scope and the range finder will determine range and relay that to the scope and the shooter will then have the reticle illuminated with the drop already computed. This allows for a large list of calibers. Refer to SIG's website or search the web for more reviews and information. 

This scope came with the rifle that I purchased and I do not have a use for it. I am not a long distance shooter. It has not been used in the field.
