Default GPS Accuracy

Thanks for all the input -
It was the swinging the compass input I was after.

Thought process was that maybe with decent sat reception - swinging the
compass (adjustments and compass card) may be easier and more accurate with
the GPS then using traditional methods i.e.. lining up bearing points,
shadows etc with my 13 year old at the wheel and me trying to do this. Have
a 21 coastal boat with compass in 5 degree increments. Sounds like the best
idea is stick with traditional methods or farm it out. In any case thanks
for all the help and thoughts.

Oops....I also forgot TIME. GPS does provide very accurate TIME to
make the calculations in my other post....

Sorry....(blush)

Kind of new at this. Any thoughts appreciated.
