Lieut. Commander Dinger, U. S. N.,1 and Mr. Gillmor,2 of the . Sperry Gyro Company, have written articles on the "Gyro Compass in Service," which were, of necessity, partly theoretical. The following conclusions were reached from actual experience with the compass on the flagship of the Atlantic fleet.
It was found that the gyro compass greatly lessens the work of the navigator. No compensation of the compass is required other than a shifting of the lubber's ring for a constant deviation, thus doing away with the necessity of swinging ship, with its attendant loss of time and inherent uncertainty.
The true course is shown at all times, so that the troublesome and changing variations and deviations do not have to be reckoned with. The compass is not affected by the training of the turrets or boat cranes, particles of iron near the binnacles, or changing sub-permanent magnetism of the ship. No checking up at the standard compass with the steering compass is required, with a set of deviation tables for each to complicate matters.
