Thread: Fish Finder Reading Tips

Here's a short video showing how 2d sonar works (it's a HB advertisement but the basics are the same for all brands) ...

One important item the video does not explain....

*The unit xducer is "pinging" (sending) the acoustic sound pulse thru the water at several times per second....
*The processed reflection data from each single "ping" is displayed along the right vertical edge of the 2d screen (about 1 pixel wide)....
*Then the next ping's processed data is also stacked on right vertical edge of the 2d screen pushing the previous displayed ping data to the left....
*This "stacking" of each ping's data at the right of the screen and pushing the previous ping's data to the left .....creates the "scrolling" effect seen on the 2d display...

So, in effect...only the very right-most vertical edge of the 2d screen is actually what is directly under the xducer....everthing else displayed to the left on the 2d screen is "history" and what the xducer has already passed over....
