The RetroTrip has sufficient functions for all the major competitive historic events and features fiddle-proof electro-mechanical clicking digits. The unit offers instant 'one in a thousand' calibration for any wheel changes and, like all Brantz meters, accuracy is excellent. The RetroTrip can be used with a wide range of motion sensors: the wheel type sensor or speedometer type being the most popular. As ever, the fitting and calibration of the meter is a simple and efficient task.

N.B. Older cars with 6V electronics or poorly performing 12V charger systems should use the BRANTZ POWER CONDITIONER to produce a correct and reliable voltage source.
