Portable Digital Fish Finder with LCD Screen for Marine Use Easy-to-Read 7-inch

Basic Scopes: Multiple basic scopes, Meters: 5, 10, 20, 40, 80, 150, 300, 600, 1000; Feet: 15, 30, 60, 120, 200, 400, 1000, 2000, 3000; Weight: 3, 5, 10, 20, 40, 80, 150, 300, 600; Passi Braza: 3, 5, 10, 30, 50, 100, 200, 350, 600, changeable in system menu. High performance: The electric signal generated by the transmitter is converted into an ultrasonic signal by the transducer. The reflected signal from intermediate objects (such as fish schools) is received by the transducer and converted into an electric signal, which is amplified by the amplifier section and finally displayed on the screen. Depth detection: It takes advantage of the fact that ultrasound travels through water at a nearly constant speed of 4,800 feet (1,500 meters) per second. The depth of an object can be determined by calculating the time difference between sending a sound wave and receiving the reflected sound wave. Color Display: The image displayed by a color digital fish finder consists of a series of vertical scan lines, each representing a snapshot taken below the boat. The series of snapshots are accumulated side-by-side across the screen, and the resulting contours are displayed. Key Features: This color digital fish finder measures the distance between the transducer and underwater objects such as fish, lake bed, or ocean floor, and displays the results on a 7-inch color screen. 1.
