The M-485B Horn Signal Controller provides for the automatic control of electric or air operated horns in conditions of restricted visibility (fog signaling). Designed for use with motor or sail powered vessels, the M-485B provides both underway and stopped signal codes per IMO Navigation Rule 35, (COLREGS Part D, Rule 35).
