The Bushnell Velocity Speed Gun is perfect for initial installation testing and verification, as well as daily speed verification on your zip lines.
The Bushnell Velocity Speed Gun’s combination of cost, portability, and ease of use make it the best choice for reliable speed measurements. The Speed Gun uses both mph and kph making it easy to correlate to the zipSTOP braking charts, and is accurate to within +/- 1 mph. The range allows the operator to be safely out of the way of incoming test weights or riders.
During zip line installation and testing there is inevitable variance in actual arrival speeds versus arrival speeds calculated by modeling. This difference can be attributed to friction, wind speed and direction, cable temperature, and cable tension. By measuring the true velocity of various rider weights, it’s possible to control landing area size and ensure the zipSTOP is being used within recommended parameters.
