That isn't very useful to the charter and head boat operators that
have accurately marked spots out of sight of land. You might find
your way home with the map and compass, but you'll play hell finding
those three holes 5 miles apart...... 30 miles off shore....



1. Transfer coordinates from GPS screen to chart.

2. Draw a rhumbline from current position to the coordinates

3. Taking current into account, follow course at known speed for amount of
time
required to reach fishing hole.

At least this *used* to work, before GPS. :-)

Sure, Chuck. It's sometimes hard to consistently find the same structure on
the Gulf floor even with differential and WAAS. Try to find the exact 15
foot wide piece of structure with 2 feet fo relief in 60 feet without GPS.
It ain't gonna happen.
