Explore the Benefits of GPS

GPS devices from companies such as Garmin, Magellan, TomTom, and Lowrance work anywhere in the world, 24 hours a day, in any weather condition. Once you buy a GPS device, you only need an unobstructed view of the sky to use it; you don't even need to subscribe to a service. A GPS Device receives data from a network of satellites in geosynchronous orbit around the Earth and uses the information to calculate your precise position. By locking into three satellites, GPS can tell you your latitude and longitude. With a fourth satellite in view, GPS calculates latitude, longitude, and altitude. Use GPS anywhere you need accurate data to help you navigate. GPS at work: Rescue crews, firefighters, archeologists, geologists, surveyors, mappers, boat captains, pilots, dispatchers, tour guides, and military personnel use GPS devices to perform their jobs. GPS at play: Take your GPS device hiking, camping, mountain climbing, biking, snowmobiling, skiing, hunting, boating, fishing, touring, and flying so that you can find your way on land, at sea, or in flight. GPS on the road: Recycle all the maps in your glove box and put a GPS device in your car. A GPS device equipped with mapping software gives you street-level directions, which can prevent you from getting lost in a bustling city. It can also select an optimum route from point to point and help you make informed choices about where to stop along the way.

Determine Which GPS Device You Need

GPS devices fall into three categories: Automotive GPS: GPS Car devices built expressly for car use often include built-in maps or allow you to download mapping data. Many also provide voice directions so you can keep your eyes on the road, touch screens, and mounting options. Handheld GPS: Take your handheld GPS device everywhere. Handheld GPS units fit nicely in your pocket, backpack, or mount easily onto your dashboard. Marine GPS: Marine GPS devices designed for use aboard marine vessels and watercrafts boast a rugged waterproof design and may also float. They often include onshore and offshore maps, chart-plotting functions, and a screen that's clearly visible in sunlight. Some even have the ability to predict tides or locate fish.

Find the Right GPS Features

GPS Devices have a variety of features and options. Accuracy: Most GPS devices will pinpoint your location within 15 meters (about 49.21 feet). Interface options: GPS devices come in a variety of screen sizes and may be monochrome or color. Expect larger color screens to cost a bit more than devices with a monochrome screen. Color screens provide more detail, but use more battery power. When you look at item listings, evaluate the image the seller provides and make sure the screen looks like it works for you. When shopping for an automotive GPS device, look for touch-screen navigation, audible voice prompts for driving directions, and a trip computer. They will help you keep your eyes on the road, and the trip computer will let you know how much further you need to go when driving from point A to point B. Maps: Most GPS devices include built-in software such as U.S. street maps. You can also buy additional software, such as European maps. Data storage: Many GPS devices come with built-in maps, but you can store even more if your device supports removable Secure Digital or CompactFlash memory cards. Mapping data doesn't take up a lot of space and many units even come with a 128MB card. Weather resistance: Like all electronics, you'll want to keep your GPS device out of the water and try not to drop it. Look for a GPS device with a rugged design and weather-resistant features if you plan to use it outdoors
