None to leave the field empty iii Repeat the above step to set the other data fields Northstar FISH 457 467 Installation and Operation Manual 15 3 Sonar fishfinding Introduction Sonar functions require the optional sonar transducer to be installed and set up This section explains how to interpret the sonar displays when and why to use the different frequencies and how fish are detected and displayed 3 1 Using the 457 467 The 457 467 uses a sonar transducer attached to he hull The transducer generates an ultrasonic pulse sound that is above the hearing range of the human ear which travels down towards he bottom at a speed of about 4800 ft sec 1463 m sec spreading out into a cone shape When the pulse meets an object such as a fish or the bottom it is partly reflected back up cowards the boat as an echo The depth of the object or bottom is calculated by the 457 467 by measuring the time taken between sending a pulse and receiving the echo When an echo has been returned the next pulse is sent The 457 467 converts each echo into an electronic signal displayed as a vertical line of pixels The most recent echo appears on the extreme right of the display with the older echoes being scrolled towards the left eventually disappearing off the display The scroll speed depends upon the water depth and scroll speed setting See sections 8 2 and section 3 2 for more information The appearance of
