Don't let bullet drop get the best of you. Invest in the Sig Sauer Kilo3000BDX Rangefinder Binocular. Pairing directly with your scope, this Rangefinder setup sends impact point correction data directly to your scope. BDX employs Sig Sauer's Ballistic Data Exchange (BDX) system, using ballistic info uploaded on the free BDX App, distance to target, and environmental data to determine where to aim to compensate for angle, bullet drop, and wind. The Applied Ballistics Ultralite feature has a bullet database and support for G1 and G7 coefficients. Input up to 25 ballistic profiles for the ammunition you use. The binocular also displays the holdover and windage information in MRAD and MOA, in your choice of angle-compensated or line-of-sight, for use with non-BDX scopes. Take a break from the tediousness of calculations and come to depend on this do-it-all optic.
