A speed baris a system that allows the pilot to lower the angle of incidence of the wing by pulling down the leading edge. In doing so, the drag is decreased and the wing speeds up. As we can see, a paraglider is a quite complex wing and an experienced pilot has many means to tune the wing to the existing conditions.
Also referred to as LIDAR (light detection and ranging), laser speed guns use light in extremely fast pulses to detect an object's speed. It has a range of 1,000 feet to 4,000 feet, and it's very accurate. One of the advantages of laser speed guns is that they're nearly impossible to detect beforehand.
