What is Rangefinder Calibration Process Before A Hunt?

Setting the Ranging Mode

Before calibrating your rangefinder, ensure it’s set to the correct ranging mode for your hunt. For archery, use the “First Target Priority” mode, which prioritizes the closest object in the scene. For rifle hunting, use the “Range Priority” mode, which displays the farthest object in the scene. Check your rangefinder’s manual for specific instructions on how to switch between modes.

Adjusting Angle Compensation

Angle compensation is crucial for accurate ranging, especially when hunting at long distances. Most rangefinders offer various angle compensation settings, ranging from 0-45 degrees. For example, the Leupold RX-1200i offers 4 angle compensation settings: 0, 10, 20, and 30 degrees. Adjust the setting to match your terrain and hunting style. If you’re hunting in steep terrain, use a higher angle compensation setting to ensure accurate ranging.

Calibrating the Rangefinder

To calibrate your rangefinder, find a known distance target, such as a benchmark or a marked tree, within the rangefinder’s maximum range (typically 1,200 yards). Take multiple readings to ensure accuracy, and adjust the rangefinder’s settings as needed. For example, if your rangefinder consistently reads 10-20 yards off, adjust the zero-point setting to compensate. This will ensure your rangefinder provides accurate readings throughout your hunt. Check your rangefinder’s manual for specific instructions on how to calibrate the device.
