Sig Sauer Kilo 2400 BDX Rangefinder Review

Sig Sauer has produced some incredibly efficient rangefinders in recent years and their Sig Sauer Kilo 2400 BDX Rangefinder is perhaps the company’s best model yet. The Kilo 2400 BDX Rangefinder utilizes the same Ballistic Data Xchange capability that other Sig Sauer BDX products have become wildly popular for.

This technology allows the rangefinder to work seamlessly with a Sig Sauer Sierra 3 BDX riflescope to feed information back and forth which will calculate and send ballistic data via Bluetooth directly to the Sierra 3 BDX’s riflescope’s reticle.

The Sig Sauer Kilo 2400 BDX Rangefinder has a wide array of features that set it apart from other rangefinder products on the market for 2021. Many of these new features are a big step up for a product that’s becoming known as one of the most capable rangefinders in the outdoor industry.

The Sig Sauer Kilo 2400 BDX Rangefinder is able to integrate and work with the Sierra 3 BDX riflescope, as well as the Sig Sauer BDX app that’s compatible with iOS and Android smartphone and tablet technology.

There is no denying that this rangefinder model is easily among the best of the best that’s available on the market for 2021. One of the main drawbacks that might prevent shooters and hunters from purchasing the Sig Sauer Kilo 2400 BDX Rangefinder is the product’s high cost.

Thanks to its BDX technology, this particular rangefinder is able to work alongside Sig Sauer’s BDX riflescope, as well as in conjunction with the Sig Sauer’s BDX app that can function with smartphones or tablet devices.

Notable Features

The Sig Sauer Kilo 2400 BDX Rangefinder is made with SpectraCoat anti-reflective coating  technology that offers superior light transmission, as well as almost the best possible optical clarity that can be achieved through a small lens product like a rangefinder.

The Kilo 2400 BDX utilizes what’s known as LightWave DSP technology for what many deem to be the fastest and longest-distance rangefinder engine on the market for 2021. This engine is incredibly fast and accurate and operates using HyperScan technology that allows it to range up to four targets per second when being used in continuous scan mode.

RangeLock mode allows users to range an object and the engine will report as the last ranged result while allowing the user to record other distant targets.

The Embedded Applied Ballistics Ultralite comes with a bullet database that allows the user to save and easily access up to 25 different ballistic profiles from G1 to G7. This allows the rangefinder to operate to an incredibly accurate level quickly and easily as it relates to a number of different caliber and weight bullets.

The Sig Sauer Kilo 2400 BDX Rangefinder also supports Applied Ballistics External for pairing KILO products with a Kestrel for a wider and more efficient onboarding of ballistic profiles.

The Advanced OLED display is able to give users an extremely accurate and precise lock on where their bullet is likely to strike the target.

When using the Sig Sauer Kilo 2400 BDX Rangefinder along with the Sierra 3 BDX riflescope, the rangefinder is able to  provide a smaller, more precise target circle reticle along with milling features, as well as ballistic information and details that include items such as holdover, target mode, angle, density altitude and shot angle.

The Sig Sauer Kilo 2400 BDX Rangefinder is also able to function at a higher level than other models in low-light conditions by using Lumatic Display.

This function is able to automatically calibrate display brightness as it relates to changing ambient light conditions outside, making it much easier for the user to distinguish the reticle and digital display of the rangefinder when light is fading with sunset or just emerging with the morning sunrise.
