Q1: Can the standard header be used alone? What will go wrong?
answer:Jiaming’s standard meter contains GPS positioning, so it is used in outdoor GPS signal coverage areas.No problem. But if your riding area is outside the GPS signal coverage area(Such as indoor cycling training, etc.), The stopwatch cannot completely record your riding speed.
Q2: Why buy a speed sensor alone? Is there no speed without buying?
Answer: Because the standard meter of Garmin is built-in GPS positioning, the speed and distance can still be displayed without a speed sensor within the coverage of GPS signal!But because the distance and environment that most riders ride have changed(For example: indoor cycling training, etc.)GPS cannot cover or the signal is weak, which will affect the accurate calculation of distance and speed! Simply put, after adding a speed sensor, you can ride any area without worries and get more accurate riding data!
