This is truly an awesome product for the price.  In addition to the unit, the package includes the user manual, computer link cable, wrist strap, and batteries.  The main manual is easy to follow and is very descriptive.  I had the unit up and running in just minutes.  After I had initialized the unit, I had had a 3D satellite signal with WAAS within 10 seconds.  The unit's reception was very good.  The satellite tracking map allows you to see all of the satellites and WAAS stations in your area and the signal strengh.  The unit worked well under all of the outdoor situations I tested it, even under large oak trees.  I was even able to maintain reception inside my two-story brick and stone house.  The unit is easy to use and quick to learn.  It is very easy to switch between the screens you want and the included basemap shows major roads and various points of interests across the country such as parks, airports, lakes, rivers, etc.  It is very simple to zoom in and out of the map and the unit contains a handy panning feature which lets you view areas around you.  Creating waypoints and tracks is also very simple.  You can even designate the icon you want to represent each waypoint as well as type in notes about a specific waypoint. The unit can tell you exactly where you are to within three meters and will also tell information about your altitude, speed, heading, eta, distance, sun/moon orientation, backtrack, waypoints, etc.  Every time I use it, I discover more features.  You can even check the phases of the moon for your area and see when the fish will most likely be biting for anywhere on the planet.  The unit is even useful for nightime operation.  It has two different backlight intensities, depending on your preference. I spent a long time researching various GPS units and this is by far the best value, especially with the rebate offered by Magellan. I would definetly suggest this product to anyone who needs (or wants) a GPS unit.  I can't wait to try out Geocaching!
