Echo sounders - Transducers (Magnetostrictive, Electrostrictive, and Piezoelectric)

This video uses animations to explain the different types of transducers used for echo sounding devices used on ships.
Echo sounders are used on ships to measure the under-keel clearance and the depth of water for safe navigation to take place.

Thanks for the video,
12:49 to make one piezoelectric like this for experimentation, what would i need ? i have the fish finder main unit (with the screen, Humminbird Matrix 35, 200 khz, 500 watts rms !! i think) lost the transducer ; could i build a stack of those cheap piezo discs?

Thank you that was so helpful but how could i get slides links

Stop reading from a book and explain in simple language
