[. . . ] The second return is most likely to occur in shallow water and in areas of relatively hard bottom. The 300TX uses advanced signal processing to further evaluate any sonar return between the surface and the bottom. For Instance, a small school of bait fish usually appears as a dense cluster of individual dots. If the return meets certain additional criteria, a fish symbol will be assigned. There are three different size fish symbols used to indicate the intensity of the sonar return. While signal intensity is a good indicator of relative fish size, the different species of fish have different sonar characteristics, so it is not always possible to distinguish fish size between varying species. The signal intensity is "normalized" for depth so that a small fish close to the boat does not appear as a large fish symbol. ID+ adds an additional piece of information to help the user locate fish. On selected fish symbols, the digital depth of the designated fish is drawn to help locate the fish vertically. This is especially helpful in setting bait depths or for downrigger operations. The specific fish symbol indicates the type of sonar beam the fish is detected in. This gives you a reliable indicator of side to side location relative to boat movement. Fish symbols which are hollow are detected in the outside two beams. Hollow fish symbols facing to the left are detected in the left beam, and thus the fish is to the left side of the boat. Solid fish symbols represent fish in the single center beam, and these fish are directly under the boat. Control Functions The 300 TX uses a simple, five-button keypad for all user input. Press any button and an audible "chirp" confirms the control input. If a button has no function or is inappropriate for the situation, and audible "error" is heard. The Power button powers the 300 TX up for normal operation. When the unit is on, POWER turns the unit off. POWER can also be used to go directly into Simulator mode. To enter Simulator, with the unit powered off, press and hold POWER for several seconds until a continuous chirp is heard. [. . . ] The Wide-Side transducer has four views available: Left, Right, Down, and Both. These views are controlled by the View Menu, which is only present when operating in Wide Side mode. The default view is both, in which information from both the left and right elements are display in screen. The digital depth of the water beneath you r boat is always present. [. . . ]
