3 INSTALLATION PREPARATION INSTALLATION OVERVIEW display on the control head. It should be installed in contact with thesurface of the water in an area that has smooth water flow - usually on thetransom of the boat. There are several mounting options for thetransducer. Review the following section t...

4 Inside the hull installations require no holes be drilled into the boat andthrough experimentation, high-speed operation comparable to transommounting can be achieved. Two part, slow cure epoxy is required to gluethe transducer in place. ALTERNATE TRANSDUCERS AND MOUNTING METHODS The 450TX comes w...

wood or metal, (which do not conduct sonar signals) make inside the hullmounting inadvisable. Thru-hull mounting may require the use of a fairing block to level thetransducer with the waterline. Also, since special tools and knowledge maybe required to perform this type of installation it is best to...

USING THE 450TX HOW SONAR WORKS 6 HOW SONAR WORKS Your Humminbird unit uses sonar tolocate and define underwater objects,define the bottom terrain, as well asdetermine distance. Sonar technology is based on soundwaves. Your Humminbird unit sendsout a sound wave signal. With thissignal it determines ...

7 USING THE 450TX SIMULATOR OPERATION Actual depth capability depends on factors such as bottom hardness, waterconditions, and transducer installation. Units will typically read to deeperdepths in fresh water than in salt water SIMULATOR OPERATION The 450TX contains a simulator that allowsyou to use...

FEATURE MEMORY If your 450TX is installed with a transducer connected, any changes youmake to the set-up or User Options (see Control Functions) while inSimulator are retained in the unit’s memory. This allows you to usesimulator to experiment with the various set-up options, and retain yourselected...

Bottom. The graphic depiction of the bottom provides the user with an effective tool for understanding the composition of the bottom. The FSTNtype display uses 4 discrete levels of gray to indicate the intensity of thereturned sonar signal. The 450TX can display even the smallest sonarreturns with l...

Second Returns. When a sonar signal is reflected off the bottom back to the transducer, there is often enough energy left in the signal to be reflectedoff the surface of the water back to the bottom a second time. Secondreturns appear as a slightly weaker bottom representation exactly twice thedepth...

15 USING THE 450TX MENU FUNCTIONS Several of the menus are multi-step. In some situations if an adjustment ismade, additional options become available for further adjustment.Examples of these multi-step menus are Depth Range, Depth Alarm andZoom. See the detailed description of each function for fur...

The Depth Range can be adjusted manually.Press MENU repeatedly until the Depth Rangemenu is visible. Two options are available: Autoand Manual. The manual setting enables you to adjust thecurrent depth range setting. The unit no longeradjusts the Depth Range to the mostappropriate range for bottom d...

Use the Arrow buttons tohighlight the desired selection. Units Depth. The Units Depth function allows the user to select the units of measurement forthe d...

26 waterline, a positive 3 will show the correct depth from the surface of the water. Another frequent use of depth offset is to show the depth beneath the deepestpoint of the hull. A negative value equal to the distance from the transducerlocation and the deepest point of the hull will have the sam...

ADVANCED FEATURES USING DIAGNOSTIC If you are using multiple transducers, switch between transducers toconfirm the connections for each. Boat Speed/Water Temperature Connection. Other connections tested include the boat speed and surface water temperature sensors. Theseaccessory sensors can be purch...
