Greetings again fellow paddlers. In regards to GPS accuracy and selective availability, a friend sent me this web site: http://www.igeb.gov/sa/diagram.shtml this graphicaly demonstrates the difference in position accuracy with SA turned off. There are still many things about GPS I don't understand, but if you have the correct datum, a sufficient number of satellites in view, and a system that is tweaked, then you ought to have a pretty good idea of where you are on the map.
