Can anyone tell us how to 'project a waypoint' on the good old |
|
yellow etrex H |
|
What's foxing me is I can only enter tenths of a mile - can I |
|
change that to feet? |
|
Maybe that's all I can do with the basic technology :-\ |

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 |
