That device is not a gyrocompass. The terminology in that listing is misleading; the manufacturer's web site is better: https://www.maretron.com/products/ssc300.php
The use of the term "rate gyro" in conjunction with the device being a compass makes it sound like a gyrocompass, but a rate gyro is actually just a turn rate measuring device. Note that they also mention calibrating the device for deviation; deviation is the term for the difference between true heading and magnetic heading.
