Adjusting the bearing

The Horizontal view presents the 360 degrees area around your vessel from a bird’s eye view. For the other views you must define the horizontal direction of the beam. Use Bearing to adjust the horizontal angle referenced to the vessel heading. You can also select the bearing line and drag it sideways.

The Bearing function controls the horizontal direction of the Vertical view, the audio beam and the beam in each Inspection view. The current bearing applied to the Horizontal view is shown with a solid line pointing out from the sonar position.

  • The bearing for the Vertical view is controlled by the bearing in the Horizontal view.
  • If you use a presentation mode with two horizontal views you can set Bearing to two different values. Both bearing lines are shown in the Horizontal view. Both bearings are shown as continuous lines pointing out from the sonar position. The bearing in Horizontal 1 is shown with a solid line. The bearing in Horizontal 2 is shown with a dotted line.
  • If you use a presentation mode with two vertical views you can set the Bearing function to two different values. Both bearing lines are shown in the Horizontal view. The bearing for the Vertical view is shown with a solid line. The bearing for the Vertical 2 view is shown with a dotted line.
  • The solid bearing line in the Horizontal view controls the audio beam. If you have two Horizontal views, the solid line in the Horizontal 1 view controls the audio beam.
  • The area covered by the vertical beam is shown as a triangle in the Horizontal view.
Note:

The choice you make is by default only applied to the currently selected (active) view. The active view is identified with a thicker border.

By default, a new manually initiated tracked object is automatically given priority status. The priority is identified with a "P". The bearing and tilt settings are automatically adjusted to follow the movements of the tracked target. The bearing line is automatically locked on the object to reflects its bearing.

Procedure

  1. Click in the view you want to activate.

    The active view is identified with a thicker border. Unless you use the Apply to all function, all changes you make will only be applied to this view.

  2. Use the joystick to make the adjustment.
    Tip:

    Optionally: Turn the relevant rotary switch to make the adjustment.

    The Mk2 Operating Panel is fitted with three rotary switches. The switches are identified with numbers. Each switch can be assigned a function related to range, gain, bearing or tilt. Investigate the functionality provided on the Operating Panel page. This page is located in the Installation dialog box.
