Since revolutionary bikes was the last item on my Have To Have list, this little Garmin Edge 205 Cycling GPS unit is the perfect companion to be attached to one of them. A little device like this is very useful for many different reasons, which you will see in a moment. Here is a little rundown of its advantages: The Edge 205 attaches easily on your handlebars or seat stem with its bike mount. The only thing you have to do next is to acquire a satellite signal and go! It is both lightweight and rugged and with our free software Garmin Training Center, you can analyze data with interactive graphs to chart your speed, time, elevation or even heart rate. There are many valuable uses for this unit: Automatic speed, distance and time measurements, and even at what altitude you are and even how many calories you burned! The Edge 205 then records this data for you to review later. Wait, there’s more! The Edge 205 can also track your heart rate, the cadence and even your climb and descent. Its GPS unit is highly sensitive and will track your position even when you are under a canopy of trees. If you don’t have a companion, there is a function called the Virtual Partner, who lets you race with a virtual competitor and if you would like to race against yourself, you can store your performance from a previously recorded event. The Auto Pause has the ability to pause the timer at lower speeds and when you speed up again, it will resume. You can also set up a set point at a certain location, or after a certain distance, and have the Auto Lap do a new lap calculation for you. I can already see myself being addicted to this valuable new assistant! Come and see.
