1. screen and use the UP ARROW to select AUTO Zoom Zoom is similar to Depth Range because it controls the range of information displayed on screen Zoom however allows selection of ranges beneath the surface so any Depth Range area of water between the surface and the bottom can be enlarged to provide more detailed information By using the full display to show a small area of coverage the effective display resolution is increased and the unit s ability to separate close targets is enhanced There are four Zoom ranges available 7 h 15 30 and 60 These ranges are not directly user controlled but are instead dependent on the current depth range In shallow water when the 15 or 30 range is in use the Zoom range is 7 2 If the 60 or 120 range is in use the Zoom range is 15 if a 180 480 depth range is in use the Zoom range is 30 and if the 600 range is in use the Zoom range is 60 Upper Zoom Limit Lower Zoom Limit USING THE 105SX MENU FUNCTIONS The Zoom range is shown on the left side of the screen and full range information is shown on the right side of the display Zoom can either operate automatically in which the Zoom range is constantly adjusted to show the bottom or manually in which the user controls the location of the Zoom range Automatic Zoom is especially helpful when looking for structure or bottom detail The Automatic Zoom keeps the bottom in v2. Selecting ID Off also disables the fish alarm ID On enables the 105SX to interpret the raw sonar data and using a variety of techniques depict appropriate target returns as one of three different size fish symbols The 105SX also displays the depth beneath the surface with the corresponding fish symbol Selecting Adjust and making incremental changes enhances the fishfinder s ability to identify sonar returns as fish symbols Increasing the value to a number greater than zero shows more fish 19 20 USING THE 105SX MENU FUNCTIONS symbols on screen In this case smaller sonar returns will be depicted as fish symbols This is useful for identifying many smaller sonar returns such as baitfish as fish symbols Decreasing the value to a number less than zero shows fewer fish symbols on screen In this case smaller sonar returns are disregarded This is useful for eliminating many small sonar returns when seeking larger species of fish The 105SX remembers this selection even when the unit is powered off Triplog Triplog provides a running log of information based on input from the Speed Temp sensor Since Triplog requires information from the Temp or Speed Temp sensors to operate if an accessory sensor is not detected by the 105SX the Triplog menu will not appear as a control menu Triplog provides seven pieces of information the current digital depth water surface temperature curre

6. 05SX WHAT YOU SEE ON SCREEN Structure Structure is defined as any object physically attached to the bottom The sonar configuration of the 105SX 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 105SX over a variety of known conditions and experiment with user functions to best represent those conditions on screen Surface Clutter 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 Thermoclines Thermoclines are sharp differences in water temperature These are easily identified by the continuous nature of the return 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 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 Thermocline Second Return
7. 105 2 Faden Operations Manual gt HUMMINBIRD THANK YOU Thank you for choosing Humminbird America s 1 name in fishfinders Humminbird has built its reputation by designing and manufacturing top quality thoroughly reliable marine equipment Your Humminbird is designed for trouble free use in even the harshest marine environment In the unlikely event that your Humminbird does require repairs we offer an exclusive Service Guarantee free of charge during the first year after purchase and available at a reasonable rate after the one year period Complete details are included at the end of this manual We encourage you to read this operations manual carefully in order to get full benefit from all the features and uses of your Humminbird product Also to register your purchase and help us learn more about you please fill out the warranty registration card at the back of this manual WARNING This device should not be used as a navigational aid to prevent collision grounding boat damage or personal injury When the boat is moving water depth may change too quickly to allow time for you to react Always operate the boat at very slow speeds if you suspect shallow water or submerged objects WARNING Dis assembly and repair of this electronic unit should only be performed by authorized service personal Any modification of the serial number or attempt to repair the original equipment or accessories by unauthorized individua
8. Fish ID The 105SX 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 is 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 USING THE 105SX CONTROL FUNCTIONS different species of fish have different ID Fish sonar characteristics so it is not always Depth possible to distinguish fish size between varying species The signal intensity is normalized for depth so 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 CONTROL FUNCTIONS The 105SX 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 an audible error is heard The unit sounds multiple chirps Power The Power button powers the 105SX up for normal operation When the unit is on POWER turns the unit off POWER can also be used to go directly into Simulator
9. 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 and composition of an object Sonar is very fast A sound wave can travel from the surface to a depth of 600 185m and back again in less than of a second It is unlikely that your boat can outrun this sonar signal The 105SX is a 200kHz single beam fishfinder The 200 kHz frequency provides excellent sonar resolution the ability to distinguish small returns or returns which are close to the bottom while providing depth capabilities to 600 185m The shape of the sonar beam is symmetrical and covers an area of approximately 24 degrees side to side and front to rear 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 USING THE 105SX SIMULATOR OPERATION SIMULATOR OPERATION The 105SX contains a simulator that allows you to use the unit as if you are on the water The simulator is invaluable for learning ho
