FAQ

Do snipers use rangefinders?
They use common sense. They can use a laser range finder to plot the distance between them and a potential target. They can use a map and grid system to plot the distances between them and a target.
What are the differences between a rangefinder and GPS?
They make judgments based on experience. One can use a laser rangefinder to measure the distance between oneself and a potential target, and also use maps and grid coordinate systems to calculate the distance to the target.
How does a rangefinder work?
A laser rangefinder is similar to a radar. It measures the distance by calculating the interval between the emission and reception of electromagnetic waves. However, it uses visible light or infrared instead of radio pulses. This device can measure distances up to 1 mile (1.61 kilometers), with an accuracy of 0.2 inches (0.5 centimeters).
