Sports GPS System

Sports that entail navigation can opt to leave out their compass and other traditional navigation gadgets and go for the digital and technologically advanced gadgets. Sports enthusiasts who are constantly on the move, like mountaineers, hikers or even runners, can sport the GPS sports watch, which works like a small computer. The disadvantage of this kind of watch is that the screen is smaller and that it has limited features.
Sat-Nav System

There is a more specialized GPS system on the market that caters to users who drive cars. This is called a sat-nav or street navigation GPS system. Not only does this type of GPS system tell you where your destination is in detailed directions, it can also tell you your car's mileage, the estimated time of arrival and the speed at which your car is going. It can also employ a voice system to "speak" to you and tell you the directions.

Technological advancements have given way to the integration of GPS into our mobile phones, whether in the form of Personal Digital Assistant (PDA) phones or the standard mobile phone. Most advanced phones have built-in GPS systems with a pre-loaded map or with an additional card slot to accommodate more memory for downloaded maps.
