Warning of Unreliability

Dis­tur­bances are ex­tran­eous and their di­rec­tion and mag­ni­tude can­not be de­ter­mined.

Should this con­tin­gen­cy oc­cur an elec­tric bell warns the nav­i­ga­tor. Any dis­tur­bances must orig­i­nate with the mas­ter com­pass and can be quick­ly and ac­cu­rate­ly lo­cated.The Sperry Gyro-Compass unfailingly points True North under all conditions of weather, ship or cargo. It relieves the navigator of calculation of errors, and tiresome compass compensations. It makes a great saving in time required to “swing ship.” The Sperry Gyro-Compass is, therefore, the Ideal Compass.
