Do You Have to be Moving for a Fish Finder to Work?

Yes! All fish finders, including the 2D, side, and down imaging, are designed to work on moving boats. They can’t function on a boat standing still or moving hardly. You may get some idea of what is underneath but on a still boat, you won’t be able to get crisp images.

In order to scan fish effectively, you have to be driving your boat properly with a predetermined chart speed. A general rule of thumb is to set your chart speed either equal to the speed of your boat or less than the speed of your boat. For the most detailed and best images scan after every one to three miles per hour. If your boat speed is 3 miles per hour then you set your chart speed at four or three miles per hour for best results. On still boats and while driving slow you won’t be able to get quality images, but if you use additional tools like Humminbird 360, and Live Imaging.

If your boat is still, and the chart speed is also very low then, the fish it will scan will appear much larger than its actual size. When it comes to estimating fish size, this is one of the major mistakes.

Similarly, the same rules apply for a very high speed, the images of the fish will look too small. In addition to this, driving at a slow speed will also stretch out the images increasing the fish size.

To make sure scanning is done properly with the right boat speed, and the right chart speed you need to scan them in a straight line. It will produce best images.
