Whether it is going out on the open or simply taking a cruise in the local city streets, safety should remain a top priority in case of emergencies. Getting lost is a possibility depending on your location and taking the fastest and safest possible route can save both time and money. A portable GPS system is just what the average consumer needs and fortunately, these devices are reasonably priced nowadays so they are just as easy to pick up as low-cost feature phones. But like mobile devices, there are high-end portable GPS units as well and knowing some buying tips can help you pick the right portable GPS system.
External Features
A portable GPS system is something that you will frequently take with you. Even the devices that you mount to cars can be consider portable as well so it always helps if the device looks pleasing because it often reflects the build quality as well. But if you plan on taking the device on hiking trips, you should consider the rugged models so they are resistant to the more extreme weather conditions and they won't get damaged if you drop them accidentally. If you plan to go boating with a portable GPS device, make sure that the device is waterproof as well. Finally you should judge the different devices by their screen size. On the road, it is recommended to get a portable GPS system that has at least a 4.3-inch display. 5-inch displays are the new trend and should be considered if the price is within reach. It is normal for handheld units to have smaller screens.
Important Specifications
Like ordinary portable devices, portable GPS systems are powered by processors and these processors determine the overall performance of the systems which can reflect the accuracy as well. Even if there are two different models that look the same, check the processor specifications before eyeing that one device that looks attractively cheaper. The more expensive device may have a better processor which means improved responsiveness. The resolution of the screen is important too because it gives an idea of how detailed the maps can be. A 480 x 272 resolution is common in a lot of widescreen devices but the 800 x 480 resolution is far superior with both maps and interface looking better.
Interface and Navigation Experience
The portable GPS system must be easy to use so the device can be relied upon when sudden situations arise. It must also have the right set of maps so proper route planning can be made. Preloaded maps reduce the setup hassle significantly and it is even better if the maps are freely updatable so newer devices do not have to be purchased.
Take a close look at the other navigational features as well since some of the more expensive devices may include some exclusive technologies that may improve the accuracy of the device or add convenience to the user. Depending on the manufacturer of the portable GPS system, the technology may have a different name so be sure to get more information about these exclusive features. Compare the list of features to the exact needs to see if the portable GPS system is worthy of a purchase.
