Quick Answer
Rangefinders can have limitations when it comes to reflective surfaces, such as metal roofs, shiny water, or white clothing, which can cause inaccurate readings or even complete failure to range.
Understanding Limitations of Rangefinders on Reflective Surfaces
Rangefinders use lasers or other technologies to measure distance to a target. However, reflective surfaces can interfere with this process, causing the laser to bounce back to the device rather than traveling to the intended target. This can lead to inaccurate readings, often referred to as “bounceback.”
Angle Compensation and Ranging Mode
To mitigate the effects of reflective surfaces, many modern rangefinders come equipped with angle compensation and ranging modes. Angle compensation adjusts the range calculation to account for the angle of elevation or depression, which can improve accuracy on complex terrain. Ranging modes, such as “First-Bounce” or “Last-Bounce,” allow the user to select which return signal to use, often providing a more accurate reading on reflective surfaces.
Tips for Shooting on Reflective Surfaces
When hunting in areas with reflective surfaces, it’s essential to use the right technology and techniques. Consider using a rangefinder with a high-quality optical system and a robust laser, such as the Bushnell Elite 1 Mile or the Leupold RX-1200i. Additionally, use the “First-Bounce” ranging mode and adjust the angle compensation as needed. For archery hunting, it may be beneficial to use a rangefinder with a shorter max range (around 500-600 yards) to avoid bounceback issues. For rifle hunting, a rangefinder with a longer max range (up to 1 mile) may be more suitable.
