St. Lucie Inlet to Lake Pontchartrain: NT+ Wide Coverage by C-Map

NT+ charts use C-Map's Guardian Technology that scans the chart area you choose in front of your vessel & sets off an alarm if you come upon shoals, rocks, sand spits or other areas that pose a threat to you & your boat. NT+ electronic charts are reverse compatible with NT charting systems but with four times the coverage. C-Map creates their object oriented NT+ charts from official paper charts & adds features paper chart can't match. NT+ charts are object oriented, vector charts faithful reproduced from official paper charts. NT+ charts include all the information from raster & simple vector charts without dilution or any manipulation of chart data or odd scaling. These charts provide seamless coverage allowing smooth panning between coverage layers of any given navigation area. Guardian then signals an alarm when boat enters the area predetermined by the user. NT+ Charts provide tidal information for primary tidal stations worldwide & secondary tidal stations in the U.S. NT+ charts give you North-up or Chart-up view options. The NavAids are presented in detailed, true color paper chart appearance. They are accurate to the best of C-Map's knowledge and any inconsistencies found are generally due to undetectable limitations in the HO charts themselves. Where due, Royalty Charges are included in C-CARD prices and paid to National Hydrographic Authorities. « less
