What reading level is The Sperry Gyro Compass book?
To quickly assess the difficulty of the text, read a short excerpt:
To swing a large ship end for end costs anywhere from one thousand ($1000) to three thousand ($3000) dollars. The Gyro-Compass is unaffected by any magnetic phenomena, and is so dependable that it makes the swinging of the ship unnecessary. In constructing a ship it is customary to make all metal parts within approximately ten (10) feet of the magnetic-compass stand of bronze, brass or other non-magnetic material. The proximity of magnetic metals seriously affects the accuracy of the com- pass.... All electric leads are run so as to clear the vicinity of the compass, as the magnetic fields set up by such conductors seriously influence the compass needle. Actual experi- ence is on record that the total installation cost of the Sperry Gyro-Compass has been saved many times over by the elimination of special metals and special run of electric leads. Before starting on a long voyage, especially with a new ship using the magnetic compass, it is customary to swing the ship through a complete circle to check deviation.
