The Super GPS is an advanced cycling computer programmed with the latest technologies & interactive features. At its core, the device offers ultra reliable ride tracking by combining three forms of measurements: GPS/ Glonass, which tracks the rider; a barometer, which measures atmospheric pressure & balances out elevation; & an accelerometer (detects movement), which cancels out GPS "drift" & saves battery life. Advanced data & training information can be collected when paired to a power meter, heart rate monitor or a speed/cadence sensor through the device’s ANT+™ and/or Bluetooth Smart connections.
