(I) Place Marker / Circle Marker / Gear
Use these buttons to place markers in the current active view.
Place Marker
Press Marker to place a generic marker in the active view. One or more markers can be placed in the view to identify specific echoes. Each marker is shown as a small triangle with or without a short identifying label. It is positioned based on the two known axes in the view as well as the tilt and bearing of the current ping.
The marker is stationary. It has a specified range, bearing and depth related to your own vessel. If the echo moves in the display presentation the marker will not follow.
Circle Marker
Press Circle Marker to place a circular marker in the active view. The circle is drawn with the same diameter as your purse. By means of the circle you can see the size of the school relative to your purse.
Tip
The Fishing Gear function allows you to define the size of your trawl or purse seine. This function is opened from the Setup menu.
Gear
Use the Fishing Gear function to define your type of fishing gear. Use the Fishing Gear Setup page to change the fishing gear properties to match your own equipment. Press Gear to place a gear symbol in the active view.
Purse seine
The gear symbol is provided as a tool to help you plan and shoot the purse seine. The symbol is intended to be used in a structured sequence that starts when you plan to shoot the purse seine. For use with a purse seine, the intended process follows:
1 To start the process:
•  Press Gear on the Operating Panel.or:
•  Right-click and select Show Gear Symbol on the shortcut menu.
This places a circle marker in the view. The size and location of the marker is defined by the choices you have made with the Fishing Gear function. Until you proceed, the marker follows the movements of the vessel by keeping its relative location to the bow. This allows you to position your vessel in the best possible location before you shoot the purse seine.
2 When you shoot the net:
•  Press Gear on the Operating Panel.or:
•  Right-click and select Place Gear Symbol on the shortcut menu.
The first timer starts when you select Place Gear Symbol.
A rectangular marker is placed in the view, and marks the position where the purse seine was shot. The circular marker is disconnected from the vessel movements, and acts as a guideline for your manoeuvring. The history line shows the movements of your vessel. Since the SU90 system knows the length of your net, it places a second marker on this line when half the length has been spent. When the entire net has been spent, a third rectangular marker is shown. In this phase the Fishing Gear function is disabled.
The first timer stops when the progress bar reads 100%. This action starts the second timer, which stops when you select Remove Gear Symbol.
3 When the process is finalized:
•  Press Gear on the Operating Panel.or:
•  Right-click and select Remove Gear Symbol on the shortcut menu to delete the markers from the view.
Trawl
When the function is activated, the Horizontal view presents a trawl illustration. The size and location of the image reflect the measurements you added in the Fishing Gear Setup dialog box.
The trawl image appears aft of the vessel symbol. When your vessel turns, the trawl presentation will reflect this, but the location and movements could be more precise. If you want an accurate trawl positioning, you must equip the trawl with relevant positioning sensors and connect the data to the SU90 system.
(J) Position Track / Target Track
Press these buttons to start position or target tracking.
Position Track
A position track permits the SU90 system to automatically control the tilt and bearing based on the movements of your vessel. It locks on a position defined by its latitude, longitude and depth. The bearing and tilt settings are automatically adjusted to compensate for the movements of your vessel.
Target Track
A target track permits the SU90 system to automatically control the tilt and bearing based on the movements of the chosen target. It locks on the target defined by its position, heading and speed. The bearing and tilt settings are automatically adjusted to follow the movements of the tracked target.
By default, a new manually initiated tracked object is automatically given priority status. Relevant information about the priority target can be found in the lower left corner of the view. If you change the tilt or bearing settings manually the priority status is lost.
Tip
On the User Settings Setup page, de-select New Manually Initiated Track if you do not want new tracked targets to become priority targets. This page is located in the Installation dialog box. To open the page, select Installation on the Setup menu.
(K) Trackball
Use the trackball to control the cursor in the user interface.
Before you can change the settings related to a view, you must click inside the view to activate it. The changes you make are by default only valid for the active view. Several of the functions offer Apply to All. If you select Apply to All your setting is applied to all the views in the current presentation mode.
