Magnetic Declination Demystified

This video explains Magnetic Declination and how it relates to the use of a map and compass. I failed to mention in the video that declination changes over time. I address this in my book "Stay Alive! Survival Skills You Need" and provide a link to the NOAA Magnetic Declination Calculator, which is also under links at SurvivalResources.com. This calculator allows you to indicate your location by Latitude and Longitude, or your zip code. It will then provide you with the change in declination so you can adjust your map. It should also be noted that I made a mistake at the very end of the video in regard to the distance you will be off if you ignore declination. I was reading from the wrong column of my chart... Don't know what I was thinking, but it's rough to get old. The correct figures are at 5 degrees, you will be off 0.09 miles (460 ft.) at 1 mile, .44 miles (2303 ft.) at 2 miles, and .87 (4606 ft.) at 3 miles. I apologize for the error but as you can see, you will be off your intended destination if you ignore declination. Check out some of our articles at SurvivalResources.com
