The Map below (copied from the above site) shows the limits of the Sea area relating to Tregantle range. It is in Whitsand bay, just West of Plymouth Sound. Firing is indicated by red flags/red lights at night. The limits are notified by signs on the cliffs by the beach if you are close inshore, or by leading marks which can be used to see if you are inside the Northern, Southwestern, or Southeastern borders of the Danger areas. In addition an extra flag/light may be shown if any vessel is inside the danger area or for half an hour before firing starts, to give time to get clear.
