In the Closed Fist Method to measure angles of elevation, what does each finger represent?

Explanation:
The idea behind the Closed Fist Method is to use your hand as a quick angular ruler. When you hold a closed fist at arm’s length, each finger represents about 2.0 degrees of elevation. So you estimate how far above the horizon the target sits by counting how many finger widths there are between the horizon line and the target, then multiply by 2. That means a single finger corresponds to roughly 2 degrees, which is why the correct choice is 2.0 degrees per finger. This method is approximate but very useful in the field when you don’t have a sighting instrument.
