Trivia

One interesting story about sextants is that they have been used in some of the most famous voyages in history. For example, James Cook famously used a sextant on his 1768 voyage to Tahiti to observe the transit of Venus. In the 1840s, HMS Beagle used a sextant to chart the coasts of South America and the Pacific Ocean. Sextants have been used for centuries by seafarers and navigators, making it one of the oldest navigational instruments still in use today. Source
