Coverage plot
When you operate with sector transmissions, the area covered by the sonar beams is limited by the chosen transmit sector angle. To make it easier to recognize the area limits, dedicated border lines may be added to the presentation.
These lines are used to outline the sector.Use this function to toggle the coverage plot lines On or Off.
If you increase the tilt, and then exceed the range using the View Range function, Coverage Plot will indicate the current practical range with a circle. The same applies if you set Range Projection to True.
This function is opened from the Cosmetics menu. Cosmetics is located on the Display menu.
