How is Angle measured and displayed?

The magnet plate installed below the oarlock creates a magnetic field which is sensed by a magnetometer inside the oarlock. The calibration routine uses a provided calibration artifact, which is basically a protractor that clips onto the magnet bar, to "teach" the oarlock what it will sense at certain angles, ensuring that it provides measurements that are accurate for your oarlock/pin/rigger setup. Angle is displayed with whole degree resolution and is accurate to +/- 2 degrees.
