A portable GPS system consists of a unit that is not limited to in-car usage. Non-portable devices are usually older models that require cable links, but the same inconvenience is found with combinations of PDAs or Palms and GPS devices that have to be car powered in order to save battery life. A portable GPS system is a unit designed for outside usage either mounted on the bike or motorcycle or carried around when hiking, mountain climbing or jogging. There are some differences between a portable GPS system and the car GPS unit, and although the functions and the features may be the same, what differs is design.

It is of paramount importance to check the calculation time, the ease of programming, the speed of satellite connection, the performance and detour options. All these make the handheld or portable GPS system models a viable choice with multiple applications. If used for outdoor applications, the portable unit should be weather resistant and waterproof in order to allow usage in all sorts of conditions without any inconvenience. The same portable device can be used in the car, since the design of new units is adaptable to a larger number of circumstances. You can for instance avoid the much dreaded traffic jams by accessing the traffic information features in the GPS device.

How can one know which is the right portable GPS system to buy? You can try the Internet and search for comparisons between the best rated models. There are in fact, web pages that provide comprehensive comparisons, reviews and price information. The pros and cons of various portable GPS system models are discussed, and you can also choose from the shopping suggestions. It is important to stress out the fact that the navigation system should be tested for more than the vocal announcements, although this feature has a considerable significance too.

Consider the relevance of a certain feature of the portable GPS system for your personal needs. And since we are talking about a portable device, the size is very important. The GPS device should fit your pocket, since any item with a large screen will have a reduced portability range. Then, the price of the portable GPS system should be on your mind. If you insist on buying a low-priced unit, you could be disappointed when the unit functions only half the time. Automatic rerouting and the possibility to calculate the remaining distance or travel time to destination are equally valuable in a portable GPS.
