How Does it Work?
The Speed and Distance System is comprised of a portable GPS transceiver, worn on the upper arm, or snapped into a waist holder, that receives signals from up to 12 satellites, converts the signals to GPS data, and then transmits the data via proprietary digital FM signals to a 100-lap Timex Ironman Wrist Receiver watch.
The Speed and Distance user is therefore able to monitor key performance information..."hands-free"... with this system, including velocity and distance traveled. The system transmits performance information to the watch via a wireless radio-frequency link. This revolutionary sports watch system is designed to measure: current, average and maximum speeds and workout distances. It features automatic time setting, a continuous odometer, and target speed and distance alarms. It delivers miles or kilometers per hour, miles or kilometers traveled...all with pinpoint accuracy. And it can measure max speed...up to 450mph.
How Can I Use It?
The target market is broad based, encompassing hands-free user applications in the sports of: running and walking, biking and hiking or trekking, skating and skiing, paddling and rowing, boating and sailing, and much more. Its applications range from the competitive to the recreational aspects of both sporting and hobbying.

How accurate is the Speed + Distance System anyway?
The Timex? Speed + Distance System boasts an accurate GPS performance of over 99% in environments with a clear view of the sky. Another way of gauging its accuracy is to say it is accurate to approximately 5 meters. On the average, overall accuracy is 95%. And, it never requires any calibration, and is not affected by the ambient terrain, surface or speed of the wearer.
What are the main differences between the 50 lap and 100 lap Speed + Distance Watches?
As you can see, there are minor styling differences between the models. There are two main functional differences as well: One has a 50-lap memory and the other a 100-lap memory. And the 100 lap model gives you the ability to set Target Speed Alarms, and Target Distance Alarms. Here?s how these alarms work: the 100 lap model has a zone feature that allows you to set the upper and lower limits for either speed or distance to measure your performance limits. When these preset limits are met, the alarm will then activate. (Your "user guide" will tell you how to deactivate them, if required.)
