Reading this book has suddenly increased the value of my fish finder to me!
I have had to realize that I made typical mistakes in interpreting the images, which I will now no longer make. The authors use clear and easy to understand language and also explain the mathematical and physical basics in a very comprehensible way.
The book is HIGHLY recommended, because what good is an expensive fish finder if you draw the wrong conclusions from the obtained images all too often? In this respect, the money for the book is very well invested.
