FreeLogic - a device for automatic measurement of acceleration and braking time of any vehicles from 0 to 30, 60, 100, 150, 200, 100-150 and 100-200 km/h, 100-0, as well as travel time and speed at the output of 402 meters with an accuracy of 0.1 seconds. Also, if you enter the weight of the car (from the catalog) with passengers, displays the approximate power of the car. It is analogous to devices such as Racelogic, Dragy and the like but at a much lower price.
