Course-Up View; Combo View - Humminbird NS25 Operation Manual

Course-Up View

The Course-Up view orients the map with your direction of travel at the top of the screen. Your
present position is always centered left to right just below the center of the view. A course
projection line connecting from your present position to a compass rose indicator displays your
direction of travel. If the course projection deviates more than 10 degrees, the map redraws your
new course at the top of the screen.
If you are not moving, the NS25 cannot determine a course and will show the map oriented to the
north.

Combo View

The Combo view is a combination of the North-Up and Sonar views. In this view you can
simultaneously view targets above and below water surface to gauge your position on the map
relative to underwater objects. The North-Up view displays in ¾ of the screen, the Sonar view
displays in the remainder of the screen.
