The Working Principle Of The Fish Finder

The use of ultrasonic transducer transmitter signal, through the air or water propagation, the use of ultrasound in the water contact object feedback back to the signal, and then through the internal processor processing, and finally displayed on the screen. Product parameters: LCD display power supply: 4 7 battery maximum detection depth: 100 meters product waterproof design.

The use of sound sonar positioning, sonar technology is based on the principle of acoustic transmission. Can detect the bottom state, contour, composition, and water depth (from the bottom of the probe). Your card is measuring the distance by sending the wave back to the time it takes to touch the object back.

At the same time through the reflection of the acoustic signal, the fish can identify the location of the object, size and composition.
