Sextant
A sextant is a traditional navigation tool that skilled maritime professionals use to determine a ship's position at sea by measuring angles between celestial bodies (like the sun or stars) and the horizon. While modern ships primarily use electronic navigation systems, knowledge of sextant use remains valuable in the maritime industry as a backup navigation method. It's similar to how pilots need to know manual flying skills even with autopilot available. Many maritime employers value this traditional navigation skill as it demonstrates a deep understanding of fundamental navigation principles and ensures safety in case of electronic system failures.
