GPS watches are the watches of the network of satellites, such as "Global Positioning System" known associate. Receiving a satellite signal to be able to pinpoint the exact location on Earth. An athletes ability ten or twenty years ago would have only dreamed of - a relatively new concept in sports watches, which, in addition to GPS technology, sports watches, clocks best achieved fitness, the ability of speed, distance and height above sea level measured . More preciselyInformation available to athletes now have much more information in real time, on hand to use to their advantage, both in training and competitions.

There are generally two levels of GPS watches sports for athletes to choose from:

Speed and Distance (2D GPS) Speed and Distance & Routes + elevation (3D-GPS)

The first GPS-clock-type is the cheapest of the two linear measure speed and distance alone. MeasureSpeed, pace and distance, but not the height or altitude.

The second type is the height it is far more power, runners or athletes because of its additional user features. Height information can be used for ascent and descent and Ion Clock with this ability can offer also calculate altitude warnings when an athlete goes to a certain height limit.

Often known as 3D-GPS, this type of system is often able to record the path information, which means that a runnerWatch for them to receive position data in a short, repeated intervals along its course, which is stored in the database and can then be transferred to clock a personal computer for viewing in a 3D software program. Many GPS watches now offers wireless data transmission that facilitate the transmission of data, eliminating the need to fiddle with the data cable.

A GPS system is very limited and because 2D GPS consumes battery power at a rapid pace, and suffer when large objectshinder their connection with the satellites, which can often be a unit of the shoe sensor are used as well. Accelerometer foot pods are tied with a precision GPS clock, but do not suffer from their defects. Many people do not understand the limits of a 2D GPS, so that when they buy a "GPS Clock" expect the complete package, which often lack on the left.

If you buy a GPS watch, always providing the desired functionality. Many 2D systems are cheaper, especially entry-level watchesseduced by Polar and Suunto, so do not approve of these services can, if you do not know what you really want it.
