Handheld GPS Units and Navigation

Global Positioning System or GPS Navigation system tools are like advanced compasses, which would show the direction. But the GPS unit just doesn’t show you where North is, it shows you how to get to places, tells you where you are and all such details. How it does this is by using special satellites that orbit in space for the simple purpose of navigation.

There are four basic types of GPS navigation units. There is the car navigation GPS system, the portable outdoor GPS unit, the marine GPS system and PDA/GPS hybrid. What we are going to be talking about is the handheld GPS unit. This is a variation of the portable outdoor GPS unit that can be carried around with you wherever you go.

The handheld GPS unit is the ideal tool for those who travel constantly and for those who travel alone. The handheld unit is versatile and convenient for the person using it. Its as simple as carrying around a cell phone but just a little bigger than a cell phone. The handheld GPS unit provides directions and information for any place on the globe. It lets you download maps and can be mounted in cars, boats or can be used even while hiking. Its of special use while hiking as it has a soft case that can also be used as a holster which is convenient to carry while hiking across mountains and rugged terrain.

Choosing a handheld GPS system
You do not need to go in a state of panic while selecting or buying a GPS tracking unit. You just need to know what you want and be well prepared.

• Know the purpose of use: GPS systems are evolving everyday and they were not as simple as they used to be. GPS units now come with extra features that can be tempting to get, but you need to be sure of what you want and need. A handheld GPS system is versatile, it can be mounted in a car or it can be carried around. Depending on your need you can choose the ones designed for outdoors and those for indoors. Those for outdoors are more expensive as they are made to be waterproof and are designed for rugged use.
• Choice to be updated: choose a GPS system that can be updated this is because roads and routes are constantly changing and the information on your handheld device will need to be updated ever so often. The best way to get around the problem of updates is to have a removable memory so that it can be easily updated with routes and software as the need arises.
• Black and white or Color: there is a variety of display screens for handheld GPS units, you can choose color display or black and white display. While the color display is much more pleasurable to use and offers clarity, it is expensive. So if you do not want a fancy device and want some thing cost effective then your option is the black and white display handheld GPS Navigation system.
• Accessories: some people consider certain features or add-ons as must have accessories. These are expandable memory or antenna whenever needed for better reception. But if budget is a problem, then the basic version of the handheld GPS system is more that sufficient.

So while handheld GPS systems are important for the globetrotter or the hiker, remember that these are expensive, they range from $100 to $1000 but this depends on how advanced the device is. At the end of it, choose wisely and travel safely.
