CMS Lap Timer Pro

Recorder displays data and lap times in real time, and it automatically records data and optionally video.

Recording is automatic and starts when the vehicle exceeds 20MPH/33KPH, then stops when the speed drops below 15MPH/25KPH for more than 5 seconds. For data, the Recorder is always running so it captures several seconds of data before the start trigger of 20MPH occurs. However, video starts at the point of the trigger.

Recording may be started/stopped manually by tapping on the red start/stop button. This feature is initially disabled to prevent accidental manual recordings; use Settings to enable manual recording.

The GPS module name (Internal, Dual, Bad-Elf, or Emprum) must be green record data.

When the location is set to Predictive, the lap timer recalculates the "current" lap time at several points around the track. The "best" lap time represents the best achievable lap time.

When the selected location has beacons defined, the lap timer uses the defined beacons to display the last lap time, and the best lap time.

Video recording is automatic and starts/stops when data recording stops/starts. This feature is initially disabled; use Settings to enable it.

To aim the camera, tap on the Video Preview button. The presence of this Video Preview button indicates that video recording is enabled.

After recording has ended, a summary screen is displayed. Below is an example of the Road Race summary:
