1-2 How the FISH 4500/4600 works The FISH 4500/4600 has two parts: - the transducer attached to the hull - the display unit. The transducer generates an ultrasonic pulse (sound that is above the hearing range of the human ear), which travels down towards the 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 towards the boat as an echo. The depth of the object or
