Why are GPS units showing up everywhere? You might find one in your rental car, on your wristwatch or even built into your wireless phone. Anti-theft fax list systems use one, heavy construction equipment might use one and having one on your boat now seems to be a requirement. Anytime we want to know our exact location on the face of the Earth, the GPS becomes fax list indispensable. Like many other technologies, feature rich GPS units are now affordable for the average person. So how do you know which one to purchase? Let's look at few things to consider prior to fax list buying your next GPS unit, but first, what is a GPS unit?
A GPS (Global Positioning System) unit has the fax list primary function of calculating its own location on land or water by using satellite signals. Once the GPS unit knows its own location, it can help the user determine direction and distance to other known locations. For instance, a GPS on a boat can tell the captain how far it is to the shoreline or how far it is to a fax list favorite fishing spot. For the outdoor sportsman a GPS can help with finding your campsite, your vehicle or your next geocache. Popular outdoor activities such as hiking, hunting, fishing, trail running, backpacking, rock climbing, buccaneering and canoeing are all made more enjoyable and safer fax list when you take along your GPS.
When buying a GPS system the first thing to fax list consider is how you intend to use it. If you plan on using it while on foot, you'll want a GPS that is lightweight, compact, weather resistant and that is equipped with features important to foot travel. WAS (Wide Area Augmentation System) is one such feature. WAS greatly increases the accuracy of your GPS, in most fax list cases to within 10 feet. Accuracy within a few meters is important for the outdoor enthusiast but not nearly as important for navigating through town in your rental car. Next, be sure your GPS has at least 12 channels of reception too. Since your GPS will only work when it receives signals from satellites fax list orbiting the Earth, less than 12 receiving channels will not get the job done in wooded areas or in steep terrain.
