First Look: Vortex Razor HD 4000 GB Ballistic Laser Rangefinder

Gun News

Vortex Optics just announced the Razor HD 4000 GB Ballistic Rangefinder, now featuring an on-board GeoBallistics solver.

Vortex Optics’ newest laser rangefinder, the Razor HD 4000 GB, does a lot more than just read distance. This is thanks to its new on-board GeoBallistics solver, made possible in part by Vortex’s recent acquisition of GeoBallistics. The device’s new capabilities allow it to sync with the GeoBallistics smartphone app to calculate drop and windage corrections based on your specific ballistic profile and the surrounding environment.

As far as the laser rangefinder itself is concerned, it’s essentially identical to the existing Vortex Razor HD 4000 in terms of appearance and capability. That means it can still range reflective targets out to 4,000 yards and less-reflective targets such as deer out to 2,200 yards. It also has the same four target modes (Normal, First, Last and ELR) as well as the Horizontal Component Distance (HCD) range mode that compensates for angles.


The only readily apparent difference is the addition of some buttons that pertain to the device’s new GeoBallistics functions, such as the BAL range mode. In this mode, the on-board GeoBallistics solver uses inputted ballistic data and surrounding environmental data to tell you exactly how to dial windage and drop compensation for a target at a given range. The device uses Bluetooth to pair with the GeoBallistics smartphone app (purchasing the Razor HD 4000 GB unlocks the “Pro” version of the app as well) where custom profiles can be built and uploaded to the device. The rangefinder comes preloaded with three common ballistic profiles and the app features a bullet library, but completely custom profiles can be added too.


The device also features on-board temperature, pressure and humidity sensors as well as the ability to take that data from a local airport. Wind measurements can either be entered into the rangefinder manually, taken from a paired Kestrel device or obtained using the rangefinder’s new Wind Bearing Capture Mode. This mode uses the Razor’s built-in compass and wind speed gauge to determine the wind’s strength and direction. After capturing this, the device provides accurate windage corrections regardless of which way it’s pointed.
