Default Question about Furuno DFF 3D ...

Furuno says the following about the DFF 3D ...

"Turn your NavNet TZtouch or TZtouch2 MFD into a multi-beam sonar that can see 120-degrees port to starboard, allowing you to see the depth and direction fish schools are moving, while displaying the seabed condition in real time."


So, how does the DFF 3D know what direction fish schools are moving? It's not like it's a Doppler radar.

Actually its not that far off. This is the same basic tech as Garmin Panoptix. It will display the fish in real time. If they are moving, you will see them moving. Kind of like a really out of focus video camera, or video game, that gives you the range and depth of what you are seeing - all in real time, as it is happening.
