Just how accurate is it?  Validation testing consistently shows timings within a few hundredths of a second of dedicated track timing systems:

(MPH readings are slightly higher than trap speeds because they are calculated at the line, not as an average over the previous 66 feet)

The MQGPS-TraQr can also be connected to a laptop or Windows Mobile Pocket PC via Bluetooth for real-time data readouts and lap times using the MaxQData software.  It also works with third-party mapping and navigation software that can handle update rates greater than 1 Hz.
