[QUOTE="Anolphart, post: 407775, member: 11434"] I assume that you are using a proper topographical map of the area? I would place the co-ordinates of your location onto the map and draw a line from that point at 350 using a protractor (your 10 west of north). Then have a look in the index as there should be a scale that shows the distances for your particular map. Use your schoolboy adjustable geometry compass to mark off the distances that you want on the line using that scale. Now you can get your co-ordinates where you marked the distances on that line and enter them in your GPS and create a route. Just remember that should you use a magnetic compass it will show the magnetic bearing. You will have to allow for the variation (again it should be marked on your map for that area) and is usually approximately 11E (in Eastern Australia), so your magnetic bearing should be 350 - 11 = 349.
