# Wndsn Range Calculator

High-precision range calculator. Companion to Wndsn Telemeters: Low tech, high utility graphical distance computers from the Wndsn applied science lab.

*The distance d from eye to measurement, and the height s of the measurement, form two sides of a right triangle, and thus determine an angle α, opposite of s. Making use of these values we can extrapolate and determine the distance D to the measured object S.*

S + S + s S + α s S Eye ddddddddddddddddd s S DDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDD S
