Get a basic knowledge of the sensor.
Introduction
Marport's Catch Navigator tells you when your trawl starts to fill. Placed on the top of
the trawl codend, it monitors the amount of catch that you have and warns you when
the trawl is full. You can even use it to determine a precise amount of fish inside the
trawl net. This way, you can monitor the contents of the codend while you are fishing,
avoid problems of overfilling and increase fish survival rate inside the trawl net. It is
recommended to install several sensors along the trawl to better monitor the filling
processes.
The Catch Navigator provides a high-definition echogram image of the volume of catch
inside the codend. In order to eiciently follow the trawl descent, echogram ranges are
configurable from 5 to 160 meters. Moreover, the sensor includes an automatic range
mode: when descending, the sensor can automatically switch to a lower range of 20
meters to get sharper pictures. Optionally, it can also track pitch, roll, depth, height and
temperature data.

Applications
Examples of data received and displayed in Scala2 application.
1. Catch status: empty / 2. Catch status: full / 3. The echogram shows the codend filling
up, until the catch sensor is triggered.
Safety Guidelines
Important: To ensure proper and safe use of this equipment, carefully read
and follow the instructions in this manual.

Firmware and Features
This section describes the firmware and features that must be configured on MASP to
set up the sensor.
To be operational, the sensor needs to be configured with two files:
•a firmware file (*.A2F): it is the firmware of the sensor,
•an application file (*.A2A): it defines the sensor features and options.
These files are generated via MASP.
Firmware
The latest version of the firmware is available for download on MASP.
Compatibility: F450-02.02.02 and aer
Features and Options
The features and options are configurable according to the type of hardware and
customer's choices.
