Vortex Optics Impact 4000 Laser Rangefinder

The Impact 4000 Ballistic Rail-Mounted Laser Rangefinder (LRF-IMP4000) is the ultimate solution for long-range competitors and open-country hunters. It provides range, ballistic, and weather data through the integrated GeoBallistics solver, on-board Environmental Sensors, and Wind Bearing Capture Mode. Designed to mount securely on any picatinny-style rail or rings with a diving board mount, the Impact 4000 is ideal for situations where smartphones may not function.

Calibration is essential for accurate target direction, inclination angle, and wind bearing. The Impact 4000 should be calibrated during initial setup and recalibrated whenever your location changes significantly (typically 30 miles or more). It is important to calibrate the device outside and away from large metal structures or objects.

Range Mode Selection allows you to choose between HCD, LOS, and BAL displays on the Setup Menu screen. HCD Mode provides the horizontal component distance, LOS Mode displays the line of sight range without ballistic correction for slope, and BAL Mode offers ballistics solutions.

The Impact 4000 offers two target modes: Normal Mode and Extended Laser Range (ELR) Mode. Normal Mode is recommended for most situations, while ELR Mode allows for ranging smaller, less reflective targets at extended distances.

With ten common default Ballistic Profiles, the Impact 4000 can be customized to reflect your specific setup. The Weather screen displays temperature, pressure, humidity, and density altitude, while the Wind & Target Direction screen shows the direction of the target and wind in degrees.

Rugged and reliable, the Impact 4000 takes the guesswork out of long-range shooting with quick, accurate ballistic corrections. Pair it with your phone via Bluetooth on the GeoBallistics app for seamless integration. Backed by Vortex's unlimited, unconditional, lifetime VIP Warranty, the Impact 4000 ensures confident performance in the field.
