The operation of Rangefinder Reticles.
Rangefinder reticle binoculars and scopes use a few different distance-calculating techniques. The simplest and most widely used method compares a scale or measurement marker on the reticle in the field of view of the scope, binocular, or monocular to a section of the thing that you are looking at that is known in size. This is commonly referred to as the Mil-Dot reticle in military and hunting circles, and the technique for calculating the distance is called the Mil-dot formula:


Mil-dot Formula
Therefore, using some basic algebra, you can determine the distance away from an item if you know its height or length. (Alternatively, you may figure out the object's height or length.)

As an illustration
Therefore, if you were on a yacht and you knew a lighthouse was sixty meters tall, and you were looking through your reticle rangefinder binoculars at it:
