There are several types of GPS devices come in cost as low as $50 to $10,000 depending on the type of GPS system. So you need to be very selective when choosing the exact models of GPS device. You need to decide exactly what you want your GPS to do. For example if your hiking there are some essential features that you are going to need. First, weight is important. Make sure you pack a lighter GPS device for your planning for hiking. Also water resistance is a must since you never know what might happen. You don't want to get caught in the dark without one that lights up.

However, many features are unnecessary for your average lover of the outdoors. Trust me it's not worth your money to buy a whole bunch of extra features you will never use. And there's always a more expensive model. Also, you don't want to buy a cheap model either. A quality GPS is worth the investment. Otherwise, you might end up having to replace your GPS just as fast as you bought it.

Here are some of the more trusted leading manufacture companies like Allied Signal Aerospace, Conexant, Datum Inc, Garmin International, Honeywell Commercial Aviation Systems, IIMorrow Inc, Interstate Electronics Corporation, Javad Positioning Systems, Lowrance Electronics, Magellan Systems Corp, Motorola, Northstar Technologies, Sony Corporation of America, Starlink Inc, and Trimble Navigation Ltd. Again, since the invention of GPS tracking is relatively new it will also be a good idea to research the manufacture.

Buying a GPS can be a big decision. Especially since the technology is always getting better, not to mention the price tag getting higher. Make sure you do all the research that you can. It could be a lifesaver.
