CommercialARPA is erratic or drops targets
General
Question
My ARPA auto radar plotter is erratic or drops targets. What could be causing this to happen?
Solution
All Furuno ARPA plotters require quality heading input with a good refresh rates. It will not work properly with a GPS NMEA heading input. Please check that you are using the proper type of heading input.
