or any kind of racing that crosses the same
starting point each lap, GPS-equipped
2-1/16” digital gauge measures if a com-
pleted lap was faster or slower than the
previous lap. Faster? Green light and the
time reduction is shown in the LED display.

just how much slower. The driver can experiment with different lines on the track and get immediate feedback on lap times.
