    I know with Garmin, the 4.0 series Bahamas charts were worthless, 5.0 and up
    were made from Explorer charts and were very detailed and accurate, although
    not quite as detailed as Explorer or digitized photocopies of Explorer that
    Maptech was selling. In the Virgin Islands, Imray & CYC charts had large
    location errors, the Garmin (6.0 I think) were most accurate of all. All
    above with Garmin 182C. Units of this screen size (~5") generally need
    either a paper chart open or a PC based electronic running, you cannot open
    up a large enough area on a 5" screen, and still see details.
