Taking the guesswork out of measuring distances and determining angles. Tools for training, practice, and high-stake situations.
A tool for makeshift navigation, and rangefinding, the credit-card sized Wndsn Quadrant Telemeter enables you to do more than merely guessing distances. Find an object of known size, or distance, or angle and measure with the appropriate scales and utilize the baked-in trigonometry to find the desired value by aligning the provided string across the various scales.
Note that you can measure any dimension; width, height, etc., the trigonometry doesn't care where in space the triangle is located.
