Frequently Asked GPS Questions
What GPS device is right for me? - The answer depends on what applications you want to use your GPS for. If you primarily want to use it to aid in your driving and for finding locations you are traveling to in your car than an In Vehicle Navigation Unit. If you want to use your GPS device for hiking or off-roading than a Handheld Unit would be the best choice, and depending on your level of map reading ability, a mapping unit may better suit your needs. If you want a GPS for your boat than a Marine Unit would best suit your needs.
What areas do my GPS unit function in? - The Global Positioning System Units function all over the world, the units are capable of giving a latitude and longitude reading anywhere on the planet. However the mapping software included with the unit usually works only in the Americas, although after market mapping software is available for many regions of the world.
How accurate is my GPS Device? - The Global Positioning System supports accuracies down to 3 meters. However it can be as large of a range as 12 meters.
What is WAAS? - WAAS stands for Wide Area Augmentation System, which basically means that the GPS unit receives information along with its GPS signal that allows it to calculate the error in its coordinates and correct accordingly. If your unit is WAAS enabled, then it is accurate to within 3 meters other wise, the range varies up to 12 meters. Three meters may seem rather inaccurate, however when viewing your location on the built in maps if applicable, or plotting your latitude and longitude on a map, no distinguishable error or deviance is noticed.
What maps come on my “mapping” unit? - Usually the included basemap is of North and South America, showing things such as major roadways, interstates, highways, rivers, lakes, towns, hospitals, etc. However in some cases more detailed maps are included on in car navigation units.
