The SIRS "Navigator" magnetic compass delivers extremely accurate readings due to its fully integrated, 4 magnet correction facility.  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. Available in different versions for Northern or Southern hemisphere, unlighted  or lighted 12/28V and has a 3-year warranty. Size: 203/8" H x 2-1/4" W. Product accessories such as installation kit, GS1 glareshield mount, SIRS MF1 short foot bracket and SIRS compass correction key are also available and sold separately.
