| | | In order to take fully advantage of the PI44 functionality, you should exploit the interfaces. In addition to the sensor data interfaces, the PI44 also includes a fully featured dual frequency echo sounder. Using dedicated buttons, the echo sounder is very easy to use. You can even superimpose the sensor data onto the echogram, and thus achieve a graphic presentation of the underwater situation. | | Apart from this, the operator unit can be connected to external navigation instruments in order to receive the vessel's position, speed and heading on NMEA format. Connected to a Simrad Combi transducer you can also read the water surface temperature. | | |
