Schools keep moving while you draw. Lead the fish instead of tracing where they were.
CHART 08 / CORALFIN BASIN / 44° LOOP
Sketch one clean loop around a moving school. Save your line, avoid protected waters, and let geometry do the fishing.
Open the chart ↘FIELD METHOD / THREE MARKS
Schools keep moving while you draw. Lead the fish instead of tracing where they were.
Wide loops catch more, but a single protected marker voids the whole survey.
Return within the start ring before the line meter reaches zero.
LIVE HYDROGRAPHIC EXERCISE
Press on open water, draw around fish, then return to your starting point. A valid line closes when both ends meet.
