The SIRS "Navigator" delivers extremely accurate readings due to its fully integrated, 4 magnet correction facility. A similar design is used on the Concord, and many civil and military aircraft. It has the same features as the "Pegasus", but is mounted with a fully adjustable bracket that allows attachment to a variety of positions including the glare-shield or the windshield. This allows the compass to be located away from magnetic influences. Size: 203/8" H x 2-1/4" W. The "Navigator" comes in lighted or unlighted versions, and has a 3-year warranty.
