Handheld Digital Depth Sounder

1.Working principle of Handheld Digital Depth Sounder

Handheld Digital Depth Sounder is a sounder that measures water bodies such as reservoirs, lakes, rivers and shallow seas, and is used to record the water temperature within 150 meters of the depth.The speed of sound waves in air is 340 meters/second and in water is about 1500 meters/second.It takes exactly 1 second for a sound wave to travel 750 meters underwater.Measure the round trip time of the sound wave.

Can calculate underwater target depth.Ultrasonic waves are sound waves with a frequency higher than human hearing and are suitable for underwater detection.

The depth sounder uses an ultrasonic transducer to both emit and receive ultrasonic waves.It displays the underwater target on the LCD screen through recording and calculates the underwater depth for display.
