nigo 5005 is both a Chrono and a data logger. This means that all data is stored in the Chrono up to 60 times per second. It allows results to be transferred to a PC or MAC for further analysis. The included analyzer program will give you a complete overview with the ability to compare results between drivers, training sessions and warm-ups. The kit contains the Chrono with free choice of receiver (magnet, loop or IR), RPM wire, power cable and a battery holder for six AA batteries. It gives you the ability to measure lap times and engine revolutions.
