SC60 and SC120 Temporary Loss of GPS Signal



​What happens when the GPS signal to my SC60 is interrupted?


​Even after the GPS signal is lost, the SC60/SC120 continues to calculate, display and output heading data for five minutes based on the back up rate sensor's calculations.  Display and signal output will stop after five minutes.  Note: One minute after the satellite fix is interrupted, the accuracy of the heading data is degraded to +/- 15 degrees.
