GPS Buying Guide

We do agree with you that buying and finding a GPS or Navigational device can be difficult and time consuming. We’ve spent a lot of time in researching everything you need to know about GPS receivers and what Global Positioning System is. Let us give thanks to the U.S. Department of Defense for developing, maintaining and hosting the GPS Satellites. They originally designed GPS Satellites for military purposes. Now, people around the world are really starting to use GPS more and more. Soon enough, people will realize how they got around all this time without one. Back in the seventies, when the U.S. Department of Defense developed the GPS satellites, they really made twenty four satellites that surrounds and tracks the earth every 12 hours. Basically, your GPS receiver gets the signals from the satellites. The GPS satellites know your exact location and can also track your location in which you’ve been already. Therefore, it can display mapping and direction data on the device. When considering a GPS device, you also have to take in consideration some of the trusted names in the business like Garmin, Tomtom, Magellan, Cobra, Lowrance and Navman. It does not mean devices from these names in the business would be more expensive either Garmin Update.

Basically, there are Automotive GPS units which are meant to be in the car which has maps or softwares built in that gives out data for directions in voice prompts. There are softwares that you can download for mapping directions. These softwares that include voice prompts are really convenient because you can be focusing on the road while driving and not getting distracted at all. Some of the most popular in car navigational units are the Magellan Roadmates, the Tomtom in car navigational gps units and of course the Garmin Nuvi units. There are handheld GPS units which are extremely convenient and which you can take it anywhere with you, in car, hiking, biking and more. Some of these devices include the Garmin Forerunner series, the Garmin iQue series, and the Magellan explorist. There is also another line of GPS devices which are considered as Marine GPS devices. These devices are used for boats and sailing that gives out maps for directions for onshore and offshore. They are more capable than just giving directions. They also have functions such as locate fish and predict tides. Some examples of these devices are the Garmin GPSMAP 430SX, the Magellan Meridian Marine Handheld GPS, the Garmin GPS 72 GPS receiver, the Garmin GPSMAP 440, the Garmin GPSMAP 192c, and more.

So, what makes one GPS unit different than the other? Well, it depends on a lot of different factors like how detailed they are in terms of providing maps and how fast and how accurate they are when they display maps for waypoints, streets, conditions of the environment. The following factors are important to know before buying a GPS unit:

· If you are looking to just get around in finding a place, then a basic GPS unit would work just fine. This is generally what users want out of a GPS unit anyway. What we mean by “Basic Unit” is that some GPS units are capable of displaying great detail of maps on a particular area or landmark and as well as surrounding areas, streets, conditions of the environment and more. GPS units depend on maps that come with the device. A lot of times you can download additional GPS maps onto your device.

· Earlier we mentioned how a GPS device can differ on how fast and accurate they can display information or data. How fast they output data depends on the number of channels a unit has. The more channels a GPS unit has, the better in reception. Reason being is that the channels of the unit communicates with the GPS satellites which in turn picks up more satellites. In car GPS units such as the Garmin Nuvi series or the Magellan Roadmate series are a primary examples of the units that will pick up more and more satellites.
