Functions and dialog boxes
Tracking Area
Use the
Tracking Area
function to define the size of the area that you want to detect
moving objects in. An invisible area - the tracking area - is created as an acquisition
area. In order for the ST90 system to find and lock on the intended target, it needs
to be kept within this tracking area. If the intended target falls outside the area, the
tracking can not be started.
Fishing Gear
By defining the type of fishing gear you are using, the ST90 system may provide more
accurate visual presentations. Use the
Fishing Gear Setup
dialog box to change the
fishing gear properties to match your own equipment.
School Select
During normal operation, the detection and estimation of fish schools depends on the
specie and the density of the school. The
School Select
function offers a selection of
species. Based on your choice the ST90 system will adjust its operating parameters to
achieve optimal performance.
Open the
School Mass Adjustment
page to adjust the density for a given specie, or to
create you own school parameters.
Environment
Environmental parameters such as salinity, sound speed and water temperature all play
an important part to present accurate echo data. Use the
Environment
parameters to
define these values. Depending on the current sea and weather conditions, you may
need to change these values frequently.
Language
You may prefer to use the ST90 system with the user interface in your own language.
A selection of languages is provided. The
Language
function allows you to select the
language to be used in the display presentations, menus and dialog boxes.
