    Re: GPS Accuracy Now.

    You are quite right:  the extent of my fishing is trolling.
    As a naviagtion lecturer I was asked to give a navigation course to a Sub-Aqua
    Club.   Whereas normal navigators prefer to avoid wrecks, divers like to find
    and revisit them.   So their requirements are for accuracy and consistency.
    GPS is, basically, a fantastically accurate system.   With technology you can
    have almost anything.   It is splendid to have an accurate alarm so that you
    know whether your anchor is dragging.   If you can link it to adjacent craft (in
    case they may be dragging their anchors) and thence by mobile phone to the owner
    dining ashore it would be even better.
    Racing folk may find the additional accuracy important though for me, as a
    cruising man, average speed is more useful than instant speed.
    I am quite content with GPS as it is!
