Ultrasonic fish finder Application
A fish finder helps detect a fish school and provides various underwater information, such as water depth, distribution of fish school, and the condition of the seabed by transmitting ultrasonic waves into the sea and receiving its reflection. Part of sonic or ultrasonic waves, which have been transmitted, reflect back to the source when they hit an object (e.g. fish school or seabed). A fish finder uses this ultrasonic reflection characteristic.
