Visual altimeter for skydiving

An altitude display device for use when skydiving, the device emitting a first color at a start freefall altitude and a second color at a parachute deployment altitude, the altitude display device comprising:

• an altimeter operative to determine an altitude of the altimeter and to generate an altitude signal representative of the determined altitude at a sampling rate so that a color of a visual display imperceptibly changes relative to a person's eye;
• and
• the visual display operative to emit a prescribed color range corresponding to the start freefall altitude to the parachute deployment altitude, the visual display in operative communication with the altimeter to receive the generated altitude signal, the visual display emitting a visual display signal at a refresh rate that a change in color emitted by the visual display signal is imperceptible to the person's eye and as the change in color corresponds to the generated altitude signal, wherein the prescribed color range comprises colors continuously blending from the first color associated with the start freefall altitude to the second color associated with the parachute deployment altitude;
• the visual display signal being variable in color within the prescribed color range associated with the prescribed altitude range, such that a change of altitude within the prescribed altitude range, as determined by the altimeter, correlates to the change of color of the visual display signal emitted by the visual display within the prescribed color range.
