3. If the wheel sensor is installed, Voyager Pro can wake up as the wheel
starts spinning.
Speed Source Help
Choose which sensor to pull speed data from:
1. Installing a Trail Tech magnetic wheel sensor will return precision speed
data.
2. GPS speed does not require an installed sensor, but may wander a little at
slow speeds and in tight corners.
Remember to input an accurate wheel size for the speed gauges to be
correct.
A speed readout is displayed on most of the main screens.
Wheel Size Help
Voyager Pro needs to know your wheel size to do precise speed
measurements. (I.e. the magnetic wheel sensor reports how many times the
wheel spins, but wheel size is needed to calculate how far the wheel travels
per rotation.)
