Wndsn Telemeter Advanced Tutorials

Making the most out of our graphical distance computers.

Extend the measuring range, jump the scales to areas with higher precision marks, or use the Telemeter for triangulation; position determination without a compass, or with only one line of positioning.

The distance from eye to measurement, and the height of the measurement, form two sides of a right triangle, and thus determine an angle. We're making use of this trigonometric principle in the Telemeters, but you can also use it with great accuracy given you have accurate values to calculate with. We originally built the online range calculator for educational and experimental applications but used it later on several expeditions for field navigation.
