[. . . ] INSTALLATION PREPARATION PARTS SUPPLIED PARTS SUPPLIED Before installing your new Humminbird fishfinder, please ensure the following parts are included in the box: · · · · · Fishfinder Transducer with 20' (6m) of cable and mounting hardware kit Mounting system and mounting hardware kit 6' (2m) power cable Publications kit It any of these items is missing, call our Customer Support Hotline. ACCESSORIES Humminbird offers a wide assortment of accessories that complement and expand the capability of your new fishfinder. These accessories are designed with the same high standards and are backed by the same one-year warranty. The Humminbird Accessory catalog included with your unit contains descriptions of the many accessories available and ordering information. [. . . ] If the bottom is soft mud or sand, the depiction will be thick and less dense. This indicates that much of the signal is absorbed by the soft bottom. If the bottom is rocky or rugged in composition, the depiction is of varying density and textured in appearance. Wave action also affects the bottom depiction. The information drawn is a distance measurement, so if the boat is moving up and down over flat bottom, the bottom depiction often appears in regular variations that match wave timing. The sonar configuration of the 300TX is optimized to give the most accurate depiction of bottom structure possible. Grass, trees, stumps, wrecks or other debris are accurately displayed, however the depiction of these objects varies with boat speed and direction. The best way to learn to interpret structure is to operate the 300TX over a variety of known conditions and experiment with user functions to best represent those conditions on-screen. Surface clutter is the layer of water near the surface that is rich in algae and other growth, and often is aerated by wind or wave action. This area of water interferes with sonar transmission and often appears on-screen as regular clusters of individual dots near the "0" line. When a sonar signal is reflected off the bottom back to the transducer, there is often enough energy left in the signal to be reflected off the surface of the water back to the bottom a second time. Second returns appear as a slightly weaker bottom representation exactly twice the depth of the primary bottom return. 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. [. . . ] The Wide Side transducer uses three different sonar elements that transmit signals to the left, right and straight down from your boat. This beam maintains a continuous digital depth readout from the bottom directly beneath your boat. The side-looking element can be used independently, or together to locate targets near the surface of the water on either side of your boat. The Wide Side transducer can be connected directly to the 300TX or used in conjunction with the standard transducer through a transducer switch. [. . . ]
