Quick Answer
To perform successful dead reckoning, you'll need a compass, a watch, and a map. These basic tools allow you to track your speed, direction, and distance traveled. With these essentials, you can calculate your position relative to your starting point.
Essential Navigation Tools
Dead reckoning relies heavily on accuracy in your navigation tools. A magnetic compass is the primary tool for determining direction, but it is also susceptible to magnetic interference. To minimize this issue, use a declination-adjusted compass and take readings away from metal objects and electronic devices.
Measuring Speed and Distance
To track your speed and distance, you’ll need a reliable time-keeping device, such as a watch. Set the watch to the time you departed and mark it every hour to measure the total time traveled. Use the speed you’re traveling (e.g., 3 miles per hour) and the total time to calculate the distance traveled. For instance, if you’ve traveled 3 miles per hour for 4 hours, you’ve covered 12 miles.
Plotting Your Course
To plot your course on a map, use the compass to determine your direction of travel. Mark your departure point and the direction you’re heading. Use the map to determine the distance traveled and calculate your new position. For example, if you’ve traveled 12 miles due north, mark your new position on the map 12 miles north of your starting point. This will allow you to accurately determine your location and make informed decisions about your route.
