• Detection Rate for Hazards on the Side of the Field Loss

  Percentage of hazards detected out of the total number of hazards on the side of the field loss

  Pre-training, Post-training (1 week)

Secondary Outcomes (3)

• Number of Head Scans to the Side of the Field Loss

  Pre-training, Post-training (1 week)

• Magnitude of Head Scans to the Side of the Field Loss
