If you're tired of trying to make out chart features on a tiny display, the Garmin GPSMAP 2010C may just what you need. Its 10.4" (diagonal) color display makes locating fish or navigating around hazards easy.

The screen of the Garmin GPSMAP 2010C is a high-resolution, 256-color LCD that's readable even in bright sunlight. Its adjustable backlighting also makes it perfect for early morning or evening fishing. And with its high-speed processor, the chart redraws and response times are fast. Since the rugged case is waterproof, the unit can be mounted above deck as well as the navstation.

To make learning to use the GPSMAP 2010C easier, especially for people who don't like to read manuals, the receiver has a simulation mode. In the simulation mode, no GPS signal processing is done, but you can see how sample information is displayed by the various navigation screens. Using the unit's buttons and menu system you can practice navigating and trip planning without going anywhere.

The GPSMAP 2010C has a built-in basemap with detailed information to guide you over both land and water. You can name and include comments for up to 3000 waypoints with selectable icons. The Tracback feature lets you retrace your path by following the track log which is automatically stored in the receiver's memory. And with storage for 50 reversible routes of up to 254 waypoints each, getting to your favorite destinations and back is simple.

When you need the most detailed maps, the Garmin GPSMAP 2010C has slots for 2 memory cards loaded with the map data. The cards used may come preloaded with map data or you can create your own maps using the data from Garmin's BlueChart or MapSource products. The receiver gives you a choice of map coordinates and has the ability to convert GPS readings to loran TDs. Or if you have previous loran trip fixes, you can enter the waypoints as TDs and they'll be converted to GPS coordinates.

The Garmin GPSMAP 2010C is both Wide Area Augmentation System (WAAS) capable and Differential GPS (DGPS) ready. The accuracy in both the regular operation mode and with these enhancement systems is easily monitored. Although reception for WAAS isn't as easy or fast as GPS, it results in a position accuracy within 3 meters 95% of the time. You can also set alerts to notify you if a differential fix is lost or GPS position accuracy falls outside a certain value.

The utility of the GPSMAP 2010C can be further increased by adding Garmin's GSD 20 sounder device. The sounder provides temperature and depth readings to aid in finding fish and navigating shallow waters. With adjustable view and zoom features, you see just the area of interest you want. And you can use the 2010C's split screen to show the navigation chart and sonar display at the same time. Sonar use also allows sound alerts to be set for a specified water depth, water temperature, or fish size.
