How did king crab fishermen find their pots before gps?

Before GPS technology, king crab fishermen relied on a combination of traditional navigation methods and physical markers to locate their pots. They often used buoys or floats attached to the pots, which were marked with specific colors or patterns for identification. Fishermen would also utilize charts, compasses, and their knowledge of the area's currents and tides to navigate accurately. Additionally, many developed mental maps and took detailed notes on their fishing locations from previous trips.
