SIRS INSTALL KIT FOR NAVIGATOR COMPASS
After hearing good comments from several people whom I trust, I replaced my Cessna P172D's 50 year old original compass with this SIRS. I have never had a more stable compass, and it was extraordinarily easy to swing. With everything on except the pitot heat, it is virtually right on at every direction. Turning on the pitot heat results in an approximate 10 degree error, so I created and installed 2 compass correction cards, but in reality, only the pitot heat on card was necessary.
