This purest of all nautical instruments, which allows seafarers to accurately determine their global position alone and without the aid of modern technology, is still required equipment on all commercial trading vessels; should electronic systems fail, a sextant can make the difference between disaster and survival. In this invaluable tutorial for beginning navigators, Pike clearly and efficiently explains the use and care of the sextant.
