The VBOX 3i is the industry standard test instrument for non-contact speed and distance measurement, used by nearly every vehicle manufacturer in the world. It offers centimetre-level positional accuracy, providing you with the data you need to verify a vehicle's side wind susceptibility and line deviation tendencies.
The VBOX determines heading based on data captured immediately prior to the test, meaning as long as the vehicle is kept in a straight line before letting go of the steering wheel, the test can be performed in any direction across the test pad.
