Contour Professional lets you see the structure of the ocean floor - in 3-D! View your favorite fishing site, or find a new one. Spin, tilt and zoom controls let you ''swim'' through the underwater world. This powerful bottom-tracking software allow fisherman and boaters to see the ocean floor in never before imagined detail. The 3-D charts are created from detailed soundings collected by private and public sources. A contour chart is made by weaving thousands of different points along the ocean floor and as a result you have a very accurate view of the underwater world. Also, a database that shows you shipwrecks and obstacles are right on the charts. Best of all, Contour works hand-in-hand with other Maptech software. Routes activated in Maptech's Offshore Navigator are displayed automatically in Contour Professional. You can plot your position on a 2-D NOAA chart and the 3-D chart at the same time. Features real-time tracking using a GPS or LORAN NMEA 0183 data, interface NMEA depth and surface temperature inputs, and adjustable transducer cone display to match sounder angle. Contour Professional includes advanced software, regional 3-D charts and the Obstacle Database that has thousands of undersea features such as wrecks, obstacles, seamounts, and pilings so you can navigate right to the best fish and dive sites - everything you need to get started in 3-D plotting.
