Handheld GPS Units and Navigation

Global Positioning System or GPS Navigation system tools are like advanced compasses, which would show the direction. However, these systems and units don't just show you where North is, they also show you how to get to places, tell you where you are, and similar 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: the car system, the portable outdoor GPS unit, the marine GPS, and the PDA/GPS hybrid. What we are going to be talking about is the handheld GPS unit; a variation of the portable outdoor unit.

The unit is the ideal tool for those who travel constantly, and alone. It is versatile, and convenient. It's as simple as carrying around a cell phone, but just a little bigger. It provides directions and information for any place on the globe. It lets you download maps, can be mounted in car and boats, and can also be used while hiking.

Choosing a Handheld GPS System

• 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. This 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 every 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. 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.
• 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 is more than 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.
