Footnotes:
1. Specifications are subject to change. Assumes the SeaTRAX is motionless and the local
magnetic field is clean relative to the user calibration.
2. For example, if the calibration was performed over ±10° of tilt, then the SeaTRAX would provide
<2° rms accuracy over ±20° of tilt.
3. Performance at maximum operational dip angle will be somewhat degraded.
