The gear symbol is provided as a tool to help you plan and 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 ST90 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.
Place Ruler
Place the cursor over the first echo. Right-click to open the shortcut menu, then select
Place Ruler
. The ruler starts wherever you place the cursor, and ends when you release
the button. The length and relative bearing of the ruler is displayed next to it. Once
a ruler has been established you can not make changes to it. You can place as many
rulers as you like in the view.
