Sig Sauer Electro-Optics Sok6K106 Kilo6K Hdx Ballistic Rangefinder 10X 42Mm Circle Reticle Od Green

The Sig Sauer Kilo6K HDX is a 10x42 ballistic rangefinder built for hunters and long-range shooters who need speed and precision in the field. This rangefinder pairs a redesigned optical system with onboard environmental sensors and ballistic computation, letting you range targets and get firing solutions without reaching for your phone or external gear—though it'll connect to Kestrel and Garmin devices if you want even deeper environmental data. The 42mm objective lens and HDX optics deliver the light transmission and resolution you'd expect from a larger system, but Sig kept the profile slim and the weight manageable at under 25 ounces.

What sets the Kilo6K HDX apart is its blend of rangefinding speed and ballistic flexibility. The Gen II Lightwave DSP engine delivers four range updates per second in scan mode and has the reach to pick up reflective targets out to 6,000 yards—realistic max ranges on deer and trees fall at 2,500 and 3,000 yards respectively. The rangefinder speaks five targeting modes (first, best, last, fog, and extended range) and five ballistic solutions: Applied Ballistics Ultralight, Applied Ballistics External, Angled Modified Range, Line of Sight, and Archery. That means you can dial in custom loads (up to 25 custom ballistic profiles), use Sig's onboard bullet database, or pair it with external ballistic software if your setup demands it. Onboard temperature, pressure, and humidity sensors feed real-time environmental data into your calculations.

The reengineered housing and rubber armor feel solid without the bulk, and updated textures on the focus wheel and diopter rings give you better grip and control. The circle reticle and segmented OLED display are clean and fast to read in the field. A single CR2 battery gets you roughly 4,000 range events per charge. Backed by Sig Sauer's Infinite Guarantee.

Frequently Asked Questions

What ballistic solutions does the Kilo6K HDX support?

The rangefinder offers five ballistic modes: Applied Ballistics Ultralight (ABU), Applied Ballistics External (ABX), Angled Modified Range (AMR), Line of Sight (LOS), and Archery (ARCH). It comes with a complete Applied Ballistics bullet database and allows you to program up to 25 custom ballistic profiles and 8 preset ballistic groups directly in the unit.

Can I connect the Kilo6K HDX to external devices?

Yes. The rangefinder is BDX 2.0 enabled with Bluetooth Low Energy and can pair with compatible devices from Kestrel and Garmin to receive real-time environmental data and deliver customized ballistic solutions. It also supports integration with onX Hunt and BaseMap mobile apps for remote waypoint creation on ranged targets.

What kind of battery does it use and how long does it last?

The Kilo6K HDX uses a single CR2 battery. You'll get approximately 4,000 range events per charge, which translates to multiple days of typical hunting or range use depending on how heavily you use it.

How fast can it range targets?

In scan mode, Hyperscan delivers four range updates per second. The rangefinder also features Rangelock, which holds and reports the last confirmed range when tracking distant targets. Range resolution is less than one foot at short distances.
