"Among all the books in print on modern celestial navigation, including mine, this one is far and away the most comprehensive, more so than even the classic tomes-Bowditch's American Practical Navigator and Dutton's Navigation & Piloting. It is rich in graphics, detailed in explanation, extensive in examples. At logical points, there are quizzes to let you track your progress."
