To make ranging and targeting, faster and easier, the SIG SAUER® BDX^TM KILO1800 Rangefinder & SIERRA3 Rifle Scope share distance and ballistics information. The integrated BDX Ballistic Data Exchange simplifies targeting by combining the ballistics and environmental conditions to calculate the holdover dot gathered from the KILO1800BDX rangefinder. Through Bluetooth functionality it's sent to the SIERRA3 BDX Rifle Scope where second focal plane stadias with OLED illumination automatically scale with zoom at any magnification level.

Lightwave DSP (Digital Signal Processing) using HyperScan technology provides 4 range updates per second in scan mode, and RangeLock^TM reports the last result when ranging distant targets. Line of Light and Angle Modified Range modes calculate incline and decline solutions.

HDX advanced optics in the rifle scope uses HD glass with SpectraCoat ultra-wide broadband lens coatings. Inside the 30mm aluminum tube is the power-saving MOTAC sensor for enhanced battery life, LevelPlex digital anti-cant and KinETHIC kinetic energy transfer indicator.

From ranging, to targeting, to impact, SIG SAUER optics connect the dots.

SIG SAUER Electro-Optics Infinite Guarantee^TM

SIG SAUER Infinite Guarantee^TM is an Unlimited Lifetime Guarantee that is fully transferable. There is no time limit, no charge and no receipt required. SIG SAUER will repair or replace your optic in the event it becomes damaged or defective, at no charge to you. If SIG SAUER cannot repair your product, they will replace it with a product in perfect working order of equal or better physical condition. It doesn’t matter how it happened, whose fault it was, or where you purchased it.

• SpectraCoat ultra-wide broadband anti-reflection lens coatings reduce surface reflections to extremely low levels across the entire visible spectrum
• Innovative KinETHIC kinetic energy transfer indicator shows you when the energy to target drops below "clean-kill" levels for more ethical shots
• SIG SAUER BDX App with low energy Bluetooth 4.0 allows creation of 25 custom ballistic profiles
