Abstract
An apparatus for measuring and displaying the altitude of a kite in the air includes a device for measuring the length of the kite line that has been unwound from the reel and a device that produces a signal to a microprocessor that represents the angle the kite line makes with the horizontal. The height of the kite, which is computed from the measured line length and angle, is displayed.
