The Compass
Explanation:
The compass was one of the foremost technological inventions that forever changed sea navigation.
Before its invention, sailors used landmarks to navigate and when it got dark, they had to stop and wait for daybreak before resuming their journey. Some other people used the inaccurate means of the sun and stars to navigate at sea.
But with the invention of the compass, all these problems were a thing of the past because the compass could provide direction despite the weather or time of the day and as a result, it opened more trade routes and assisted in the Age of Discovery.
