The Apex Pro's Predictive Lap Time Display

The Apex Pro measures the amount of demonstrated grip that you use. It also has a predictive lap display, which shows how much ahead or behind you are of your previous best. The device is really a cool device, it's got its own little GPS antenna in it.It has a memory of all the tracks, all the start finish lines. Some drivers can do isolated moments of brilliance at Watkins Glen and VIR.
