Echo Sounding How it Works x Your eyes underwater An "echo sounder" or "sonar" unit sends high-frequency sound waves down into the water below a boat. These sounds hit the bottom of the lake or sea and bounce back. The display unit measures the time delay as the signal goes out and returns. The FishFinder uses this information to display a graphic image of the bottom conditions. The system also uses this same principle to detect fish or other objects in the water, and display their size and location. This display is like a "window" which allows you to look into the underwater world. x About the transducer The transducer transmits the sound waves down into the water. It also receives the waves as they return. One type of transducer can be mounted on the transom of the boat, as shown here. Other types of transducers can be installed through a hole in the hull, or mounted inside the hull. x The Sidelooker transducer The optional Sidelooker is a special type of transducer which allows the FishFinder to detect fish beside the boat. The Sidelooker produces two powerful horizontal beams which extend to either side, just below the surface of the water. The Sidelooker transducer uses a special plastic material called "PVDF," which was developed by Raytheon Naval Systems. This allows the Sidelooker to give you the clearest possible picture of conditions underwater. FishFinder 465 Features and functions "Out of the box" operation Because of a number of automatic features, the FishFinder 465 unit is ready to operate "right out of the box." This unit includes automatic settings for the most important controls ­ range, sensitivity, and zoom. Because these settings are automatic, the FishFinder will provide useful displays right from the start. Once you become more comfortable with the operation of the unit, you can adjust these settings. PWR FISHFINDER SETUP CLEAR ZOOM A-SCP BOT LOCK 465 Excellent ability to find fish To a sonar unit like the FishFinder, the water includes a lot of background "noise." There are many conditions which could confuse a sonar unit ­ bubbles and wakes in the water, temperature differences between water layers, and so on. It can be difficult for a sonar unit to detect fish against this background of noise. Because of its advanced circuitry, the 465 is especially good at telling the difference. Fish symbols and alarms The unit provides fast, positive identification of fish in the water. It even indicates the size of a fish using eight different fish symbols. The 465 includes alarms for shallow warning, deep warning and fish warning. Clear LCD display The FishFinder display produces continuous pictures of bottom conditions and fish in the water. The display unit may be turned or tilted to the best viewing angle. The FishFinder unit can be easily removed from the boat for storage in a safe place. Dual frequency operation "Frequency" is a measure of how fast the sound waves change or "vibrate." The FishFinder uses sound waves with two different frequencies ­ 50 kHz and 200 kHz. The 50 kHz frequency scans a wide area, and penetrates the water well. This frequency is best for use in deep water. The 200 kHz frequency scans a narrower area but produces a more detailed view. This frequency is best for seeing fish near the bottom, or fish which are close together. The FishFinder can also use both frequencies at the same time. This provides good depth penetration and good detail in the display. Totally waterproof The FishFinder 465 meets U.S. Coast Guard specifications for waterproofing, so it can stand up to the hard service required on small boats. The rugged construction and sophisticated sealing methods used in this unit will ensure many years of reliable service.

The system includes a transducer and a display unit, connected by a cable. The transducer sends high-frequency sound waves down into the water. These sounds strike fish, the bottom, or other objects in the water, and return as echoes. The FishFinder then interprets these echoes and presents a display. The FishFinder 465 can handle many different jobs: · detect the presence of fish below the boat · trigger an alarm when fish are found · measure the depth of the water · set alarms for minimum and maximum depth · show the shape of the bottom · determine whether the seabed is hard or soft · measure the speed of the boat and the distance traveled · show the water temperature We are sure you will find the FishFinder 465 to be one of the most useful devices on your boat.
