[LAP1DOUG]

I have used a smartphone app called Trackmaster that was pretty cheap and worked OK for sector times. I first walked the course with the software app running to identify the course and the sector breaks that you want to use. Obviously that first recorded time will be slowwwwww.

Our local SCCA region used to place several lap timers around the course, and post everyone's sector times. That was extremely helpful because then you could see where you were gaining or losing time compared to others in an apples to apples comparison. Too bad they stopped doing that when they appointed a new solo coordinator.
