| Publisher Description: With just four required items: 1-This all inclusive book (with simple terms, teaches you how to use a sextant/navigate and includes all celestial data needed till the year 2056), 2-sextant, 3-compass and 4-universal time (shortwave radio or time piece) you can navigate the globe by using latitude and longitude derived from the sun with these four items and have peace of mind knowing that you have a reliable backup to GPS. Once you have your position in latitude and longitude, this book teaches you basic navigation (destination, heading and distance), so you will never be lost.For safety reasons and because equipment fails, batteries die, and equipment falls overboard, people going to sea should have at least two different methods of navigation. The preferred primary method is using a GPS system. This book will teach a secondary backup method of my version of the "Noon Shot Fix".If you are headed offshore, just curious about celestial navigation or have an old sextant and wonder how it works, buy this book with the other required items and you won't be disappointed. This book can be read in a short amount of time with sextant readings starting immediately. This book is a combination of basic theory, teaching only what you need for a noon shot fix and basic navigation/plotting, along with a checklist type form to calculate your position, all inclusive celestial data, many "completed" examples and information on emergency navigation.There are many other great celestial navigation techniques out there that people use every day, however many of these techniques require more dedication to learn/use. My goal was to create a simple book, that could be used by the average person with no background on the subject, and contain all the information needed that could be called on in a time of emergency. Anyone with basic math skills can learn/use this technique. |
