1. A navigational and marine system comprising:
- a sonic transducer for sensing a depth of a body of water and for generating a depth signal representative thereof;
a GPS antenna for sensing GPS satellite signals;
a display screen;
a computing device coupled with the sonic transducer, the GPS antenna, and the display for receiving the depth signal from the sonic transducer, receiving the GPS satellite signals from the GPS antenna and for determining a location of the system as a function thereof, driving the display so as to display information corresponding to the depth signal on a first display area of the display and to display information corresponding to the location of the system on a second display area of the display;
a scrolling key coupled with the computing device, the scrolling key and the computing device permitting a user to selectively adjust a relative portion of the display screen occupied by the first display area and the second display area; and
a single housing for housing the display screen, computing device, and the scrolling key.

8. A navigational and marine system comprising:
-
a sensor for sensing a sensed condition and for generating a sensor signal representative thereof;
a GPS antenna for sensing GPS satellite signals;
a display screen;
a computing device coupled with the sensor, the GPS antenna, and the display for receiving the sensor signal from the sensor, receiving the GPS satellite signals from the GPS antenna and for determining a location of the system as a function thereof, driving the display so as to display information corresponding to the sensor signal on a first display area of the display and to display information corresponding to the location of the system on a second display area of the display; and
a scrolling key coupled with the computing device, the input and the computing device permitting a user to selectively adjust a relative portion of the display screen occupied by the first display area and the second display area. - View Dependent Claims (9, 10)
