Making the decision to purchase a high accuracy GPS receiver, like the new Garmin Street Pilot GPS receivers or latest Magellan Road Mates, can make the difference between getting accurate directions and being accidentally sent off course by the device.
Accuracy, especially in tight city streets, can make certain that your GPS device stays on target during your entire trip.
Unlike a homemade GPS receiver, which usually does not have the accuracy and durability of the commercial products, the commercial products are tested and used with a reliable series of satellites.
In addition to the base advantages of a high accuracy GPS receiver, there are more benefits, as well as disadvantages. The first of the benefits revolves around being able to make use of your GPS unit in more than just a car. By being highly accurate, you can make use of them while on walks in the woods or in the city and being able to pin point your location down to feet or a very few meters.
However, with these benefits come disadvantages. The most noticeable of these lies in the fact that these systems tend to cost more. The additional price for high accuracy units tends to make individuals choose a lesser GPS. If you intend on taking your GPS unit to a variety of places, you will want to consider the high accuracy systems, as this can make the difference between safely and easily making your way to your destination or becoming lost.
When you are investigating the various GPS units, you should keep in mind that a high accuracy system is any system that pin points your location within a distance of roughly 6-12 feet.
