If your 'compass' screen can show distance to a waypoint in feet, calculate a reverse bearing.

e.g. if you want 500 feet at a bearing of 100 degrees then mark your current position, 'go to' that waypoint and then walk away until your screen says you are 500 feet away on a bearing of 280 degrees (100 + 180).

If the bearing you want is greater than 180 then substract 180, ie 280 becomes 100.

Else use a real compass!

Or if you can take the numbers home use Fizzycalc on your PC
