Wer dieses Buch nicht liest, ist selber Schuld!

No lecture, press article, report, online training, or even a 365 days support provides as much essential knowledge as this book.

After two or three illustrated explanations you will realize that without this knowledge the profitable use of a fish finder is not possible.

After the first one, I immediately bought more copies for three good fishing friends. All three of them have over 30 years of boat fishing experience and all three of them were also amazed. Each of them was able to extend his/her knowledge significantly.

Best regards and keep up the good work.

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.

I was a fish arch hunter?

A really good book to understand how a sonar/fish finder works.

My tactics when fishing will definitely change.

The book is written in a comprehensible way and you will understand a lot the first time you read it. I can only recommend it to anyone who is interested in technology.

Thank you for this great book!
