It should be installed in contact with the surface of the water in an area that has smooth water flow - usually on the transom of the boat. There are several mounting options for the transducer. Review the following section to determine the method that works for you and your boat. Determining How to Mount the Transducer The 450TX includes a model XT-6-TB-90 transducer. This tran

Two part, slow cure epoxy is required to glue the transducer in place. ALTERNATE TRANSDUCERS AND MOUNTING METHODS The 450TX comes with everything necessary for installation and operation on most boats. However, there ar

530977-1r11015E 11/6/01 12:09 PM Page 5 INSTALLATION PREPARATION TRANSDUCER EXCHANGE wood or metal, (which do not conduct sonar signals) make inside the hull mounting inadvisable. Thru-hull mounting may require the use of a fairing block to level the transducer with the waterline. Also, since special tools and knowledge may be required to perform this type of installation it is best to refer to a qualified marine technician. TRANSDUCER EXCHANGE Other transducers are available as replacements

530977-1r11015E 11/6/01 12:09 PM Page 6 USING THE 450TX HOW SONAR WORKS HOW SONAR WORKS Your Humminbird unit uses sonar to locate and define underwater objects, define the bottom terrain, as well as determine distance. Sonar technology is based on sound waves. Your Humminbird unit sends out a sound wave signal. With this signal it determines distance by measuring the time between the transmission of the sound wave and when the sound wave is reflected off an object. Your Humminbird uses the re

Units will typically read to deeper depths in fresh water than in salt water SIMULATOR OPERATION The 450TX contains a simulator that allows you to use the unit as if you are on the water. The simulator is invaluable for learning how to operate the 450TX. There are two ways to start the simulator. If the

This allows you to use simulator to experiment with the various set-up options, and retain your selected settings for normal operation. If you are using the 450TX in Simulator when no transducer is connected, any sele

The graphic depiction of the bottom provides the user with an effective tool for understanding the composition of the bottom. The FSTN type display uses 4 discrete levels of gray to indicate the intensity of the returned sonar signal. The 450TX can display even the smallest sonar returns with light gray pixels. Larger returns are displayed with darker shades of gray. If the bottom is hard and smooth, the b

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 ha
