What is the main purpose of using a laser rangefinder?

The main purpose of using a laser rangefinder is to accurately measure the distance to a target. Laser rangefinders work by emitting a laser beam towards the target and measuring the time it takes for the beam to reflect back. This technology allows for precise distance measurements, which are essential for various applications such as hunting, golfing, surveying, and military operations.

Accurate distance measurement is crucial because it informs adjustments in aim and enhances effectiveness, whether in ballistics or sports. Other options, like creating 3D images, enhancing night vision, or improving bullet speed, do not align with the fundamental functionality of a laser rangefinder, which is solely focused on distance measurement.
