GPS watches are watches that can connect to the network of satellites known as the "Global Positioning System". After receiving a satellite signal can determine its exact position on earth. A relatively new concept in sports watches, the addition of GPS technology has made sports watches, fitness watch, especially the ability to measure speed, distance and height above sea level - a skill athletes ten or twenty years ago, would onlydreamed. With more precise information at their disposal, athletes now have many more real-time information on the fingertips that can be used to their advantage, both in training and competitions.
There are generally two levels of GPS Sports Watches available for athletes to choose from:

The speed and distance (2D GPS) Speed and Distance + Lift & Routes (GPS 3D)
The first type of GPS clock is the cheapest of the twomeasure the linear velocity and the distance alone. It measures the speed, pace and distance, but no information on elevation or height.
The second type includes height information brokers offer much more power to you or any sport, for its extra features. About height can be used to calculate the rise and fall of ions and a clock with this ability can also offer high alert when an athlete exceeds a certain height limit.
Often known as 3D GPS, this type of system is oftenRegistration information is also able to track, for example, a runner can have its clock records the position data and repeated at short intervals along its path, which are stored in the database's clock can then be transferred to a personal computer for viewing on a 3D software program. Many GPS watches now use a wireless network with the transfer of data to facilitate the transfer of data, eliminating the need to fiddle around with data cables.
A GPS system is very limited and 2D dataGPS consumes battery power at a rapid pace, and suffer when large objects blocking your relationship with the satellites, often a speed sensor may also be used. Accelerometer shoe is on par with an accuracy of a GPS clock s', but do not suffer from its shortcomings. Many people do not understand the limits of a 2D GPS, so that when you buy a "GPS watch," waiting for the complete package, which often left wanting.
When you buy a GPS watch, always make sure theyprovide the desired functionality. Many of the less expensive systems are in 2D, especially at entry level Polar and Suunto watches, so do not be tempted by these offers expensive, unless you know its what you really want.
