る船舶用速度計。A sensing part that detects the speed of the ship, an amplifier that amplifies the output of this sensing part, a speed indicator that is driven based on the output of this amplifier, and a dummy that returns the pointer of this speed indicator to a specified position. A marine speedometer having a dummy signal circuit that supplies a signal to the amplifier, and a first power switch that turns on and off a power supply, the first power switch being interlocked with the first power switch; a changeover switch that supplies the dummy signal to the amplifier by turning off the switch; designated position detection means that detects whether the pointer of the speed indicator is at a designated position; and a switch that is parallel to the first power switch. and a second power switch connected to the designated position detecting means and operated based on the output of the designated position detection means, and by turning off the first power switch, the pointer of the speed indicator is automatically set to the designated position. and then automatically switch to the second
A marine speedometer characterized by turning off the power by turning off the power switch.
