Garmin GSC 10 Speed Cadence Sensor for Edge and Forerunner Series (010-10644-00)

A good companion for Garmin's Edge 305 and 305CAD cycle computers and the Garmin Forerunner 305 personal trainer, the GSC 10 monitors your cycling rhythm for up-to-the-minute results and later analysis. The self-calibrating, wireless unit measures both speed (in pedaling strokes per minute) and cadence , then provides feedback to the user for optimal performance. You can later feed the results to Garmin's Training Center software, which helps you tailor your workouts to meet specific goals and objectives.

Like the Garmin heart rate monitor, the GSC 10 attaches easily to your bike, where its sensors detect signals from your wheels and send the information wirelessly to your personal trainer/cycle computer. It's also backed by a one-year warranty.
Customer Review: What a training tool!!!
What a great training tool! I did not have a computer for my bike, but have been using my Garmin Forerunner 305 while running for some time now. I decided to purchase the cadence sensor, and am glad I did, what a great training tool and it has helped me improve my riding significantly. Highly recommended if you are serious about riding.
Customer Review: Homerun
This is my first cadence sensor so I do not have anything to compare it to. This cadence sensor combinded with my 305 has completely made my flightdeck obsolute. I was especially impressed by the auto-calibration for the speed sensor feature. No more need to measure your wheel size. Now, if Garmin can just figure out a cheap and acurate power meter there would be no need for more than one computer on your bike.

In recent times driving has become all the more simpler and exciting with the use of navigation systems such as automotive GPS systems. The time where you worried about getting to your intended destination is long gone because the automotive GPS system ensures that you get to your destination in due course without roaming about aimlessly and straying from your intended course. Honda was the first vehicle company to create the automotive navigation system as far back as the early 1980's, at that time a device known as an accelerometer was used in order to determine precise locations as the means to use GPS systems weren't available. Nowadays you have a lot of popular vendors selling automotive GPS systems as well as other navigation systems and you are free to make an independent choice.

For those who have no detailed understanding of how automotive GPS systems work, they should understand that these systems make use of satellite signals in order to determine the precise location of a vehicle. Not all automotive navigation systems make use of GPS technology and certain differences exist with other GPS systems that use data on your precise position to superimpose it on a map and determine your particular location.

Different aspects make up a complete navigation system. These different components are the aerial view of the map which changes according to the motion of the vehicle; this component is easily the most crucial component, distance gauge, distance numbers as well as the next curves bird's eye view in order to protect you from harm.

Navigation systems make use of road databases which contain a complete listing of the names and addresses of different locations which are stored as geographical coordinates. Any information that requires updating is supplied through internet technology as the vehicles moves from one particular location to the other. It also has a vector map of a particular area which ensures that it is easy to find a person or business if you have their particular name or address.

Databases which are employed in such systems can be easily kept on storage media such as hard disks or by using certain memory known as read only memory. Read only memory comes directly programmed from a factory or stored on other optical storage media devices such as CD's and DVDs. Base maps are usually stored constantly in the memory of the device because they don't change. The base maps are used to provide precise and accurate information about any current location that a user may find themselves in or which they may be interested in. Systems exist which allow for a combination of all these elements.

History has it that the navigation system that was primarily created to function with GPS was developed by Pioneer in the year 1990. Nowadays GPS navigation systems have come a very long way. You can use them not only to determine your location but to locate other essential services such as gas stations, restaurants and motels. Auxiliary functions which include messaging capabilities and the ability to watch DVD's may also come included.
