Introduction and Presentation
Read this section to get a basic knowledge of your Trawl Explorer sensor.
Tip: Click Marport logo at the bottom of pages to come back to the table of contents.
Introduction
Marport’s Trawl Explorer is your eye on the fishing gear. This sounder can be placed on your trawl
headrope or tunnel in order to send useful information to the wheelhouse.
Thanks to the sounder you will see:
• On the echogram, the trawl opening and fish entering the net.
• Also on the echogram, the distance between the footrope and seabed to see if the gear touches
the bottom.
• Depth data
• Temperature data
• Pitch and roll data
• Distance from the sensor to the seabed or footrope
The Trawl Explorer can adapt to different types of fishing methods. For example, you can fully
configure the sounding modes in accordance with your fishing method to have optimum results.
On the latest version of Trawl Explorer, the echogram displays target stength values that helps you
to identify fish.
