A portal’s scout controller is the agent that has scanned that portal more than any other agent in the last 30 days. The number of scans by that agent in the last 30 days is displayed on the portal’s detail card. When you exceed that number of scans on the portal in 30 days, you become the new scout controller. Your agent profile will display the number of unique portals where you have become the scout controller. This is an all-time stat, and is not reduced when another agent becomes scout controller on one of your portals. The value of this stat is what counts toward the scout controller medal.
The Scout Controller medal was introduced on 10 July 2020.
