There are so many GPS receivers on the market these days and it can be a daunting process to buy one. Like anything else you buy, you need to do your research and then decide which product will best suit your needs.

 

When it comes to selecting a GPS device, there are a few things that you should consider:

Application—Some GPS devices are made specifically for certain things. For example, many GPS units are designed specifically for use in a car, while others are more suited to hiking.

Cost—Perhaps the most important of all factors. Navigation systems have really come down in price lately, although they can still be costly!

Portability—If you are going on a 3 day hiking trip, the last thing you want is a large gps receiver weighing you down.

Mapping, software and updates—The roads and tracks as we know them today can (and most probably will) change. This also means updating the maps on your gps system, which can be costly.

Features—Depending on how you plan to use the gps unit, you need to consider what features you want it to have, and which ones you don’t want to be paying extra for. Bluetooth compatibility may be of use to the car gps user, while the mp3 player may be useless.

 

There are many features to consider when buying a gps device. Below is a list of common features to look for:

 

The importance of how accurate your gps receiver depends on how you plan on using it. Some gps systems come with integrated WAAS (Wide Area Augmentation System). Such systems can often have an accuracy of up to 3m.

The antennta is a crucial part to communication with satellites orbiting the earth. If the unit has an internal antenna, then you will need to make sure that the whole gps system has an unobstructed view of the sky. An external antennta allows for more versatility, allowing you to conceal the gps unit in your pocket, or use it easily in heavily shrouded areas.

 

The battery life of any portable electronic device should be considered. If you plan on taking your gps navigation system to areas of restricted power supply, then make sure your system has a long battery life.

 

The memory your device has is another important factor to consider. Just like a computer, your gps unit needs space to store data (maps etc.).

 

You should try and purchase a system with an LCD screen. An LCD screen means that the screen is clear and visible in all conditions; full sun, night time etc.

 

The amount of detail you can import onto your gps device depends on the software it runs on. Some units allow only specific maps to be downloaded, while others allow third party maps.

 

This can come in very handy, and save you a lot of money. If you accidentally drop your gps receiver into a body of water, or it unexpectedly starts raining, you don’t want to have to be finding more money to get it repaired or to buy a new unit.
