Accuracy
Besides bringing you great accuracy concerning your distance, heart rate, and over statistics, the PC8 also features GPS. However, it should be noted that the GPS feature is only for recording and takes about two to three minutes to acquire a signal. As an added bonus, this computer is compatible with ANT+ accessories.

Ease of Use
This computer really couldn’t be easier to use. The built-in sensor turns on automatically when you start pedaling. There is no touch screen, just an easy to use navigation button that allows you to toggle screens and check all of your stats. You can also keep four different bike profiles on the PC8. Before you start your ride, simply choose your bike (if it's not the same one you used last) and go.
