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 350TX includes a model XT-6-TB-90 transducer. This transducer can be mounted on the transom of the

INSTALLATION PREPARATION TRANSDUCER EXCHANGE 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 for the standard transducer. You may exchange your new and unassembled transducer for another type.

USING THE 350TX 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 reflected signal to interpret location, size

USING THE 350TX SIMULATOR OPERATION Actual depth capability depends on factors such as bottom hardness, water conditions, and transducer installation. Units will typically read to deeper depths in fresh water than in salt water. SIMULATOR OPERATION The 350TX 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 350TX. There are two ways to start the simulator. If the unit is powered off, press and hold the PO

USING THE 350TX WHAT YOU SEE ON-SCREEN If you are using the 350TX in Simulator when no transducer is connected, any selected options are lost when the unit is powered off. The 350TX will return to Factory Settings, or options selected when last used with a transducer, if no transducer is connected. IMPORTANT: A transducer must be connected to the 350TX in order to retain user settings selected when in simulator mode. If no transducer is detected, the unit defaults to pre-selected options when po

USING THE 350TX WHAT YOU SEE ON SCREEN Structure. Structure is defined as any object physically attached to the bottom. The sonar configuration of the 350TX 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 350TX over a variety of known conditions and experime

The 350TX automatically adjusts the level of receiver sensitivity based on a number of factors including the depth of the water and the level of noise present. Noise can be caused by other electronic devices, engines, trolling motors, propeller cavitation and hydrodynamic flow among others. The user has the option of adjusting the Sensitivity higher or lower based o
