USING THE TRACKER UNIT HOW SONAR WORKS HOW SONAR WORKS Your Tracker unit uses sonar to locate and define underwater objects, define the bottom terrain, as well as deter- mine distance. Sonar technology is based on sound waves. Your Tracker 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 Tracker uses the reflected signal to interpret location, siz

USING THE TRACKER UNIT 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 Tracker unit contains a simulator that allows you to use the unit as if you are on the water. The simulator is invaluable for learn- ing how to operate the Tracker unit. There are two ways to start the simulator. If the unit is powered off

USING THE TRACKER UNIT WHAT YOU SEE ON-SCREEN If you are using the Tracker unit in Simulator when no transducer is con- nected, any selected options are lost when the unit is powered off. The Tracker unit 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 Tracker unit in order to retain user settings selected when in simulator mode. If no transducer is detected, the unit defaults t

USING THE TRACKER UNIT WHAT YOU SEE ON-SCREEN Bottom Depiction Zero Line depth of the water changes, the range changes as necessary in order to retain a bottom representation on-screen. When in Auto mode, the horizontal line at the top of the screen is the “zero line,” representing the surface of the water. Occasionally there is a gap in this line. This gap indicates the unit is up- dating the display even if the bottom is not visible on-screen, or if the bottom information is not changing. New

USING THE TRACKER UNIT WHAT YOU SEE ON SCREEN moving up and down over flat bottom, the bottom depiction often appears in regular variations that match wave timing. Structure. Structure is defined as any object physically attached to the bot- tom. The sonar configuration of the Tracker unit 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 spe

USING THE TRACKER UNIT CONTROL FUNCTIONS Fish in Fish in Wide Beam Narrow Beam There are three different size fish sym- bols used to indicate the intensity of the sonar return. While signal intensity is a good indicator of relative fish size, differ- ent species of fish have different sonar characteristics, so it is not always possi- ble to distinguish fish size between vary- ing species. The signal intensity is "nor- malized" for depth so that a small fish close to the boat does not appear as

With the unit powered on, press LIGHT once to turn the backlight on “high.” Press LIGHT a sec- ond time to turn the backlight on “low,” and a third time turns the back- light off. The backlight is very effective for low-light and nighttime opera- tion. When the backlight is on, the Tracker unit will consume more power than with the backlight off. This is im

USING THE TRACKER UNIT CONTROL FUNCTIONS The ARROW buttons often can be used when no menu is on-screen. In these situ- ations, pressing the ARROW button affects the function of the active (last- used) menu. This is a short-cut to menu operation. The menu appears on-screen while the adjustment is made and times out. A frequently used menu can be adjusted very quickly using this technique. After an adjustment is made to a menu function, the menu times out after a few seconds and the unit returns t

USING THE TRACKER UNIT MENU FUNCTIONS Sensitivity. The Sensitivity function controls the sensitivity of the sonar receiver. The Tracker unit automatically adjusts the level of receiver sensitivity based on a number of factors includ- ing 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

USING THE TRACKER UNIT MENU FUNCTIONS After an adjustment is made, the menu disappears and the new sensitivity setting is in affect. If additional time is needed to study a menu, press and hold the MENU button and the menu will remain on-screen indefinitely. If you need to make an additional adjustment, press the UP ARROW or DOWN ARROW button. Depth Range. The Depth Range function controls the vertical distance displayed on the graphic area of the display. There are nine depth ranges available.

Using manual Depth Range control, you can view sonar information from the area near the surface in great detail. To return to automatic Depth Range control, press the MENU button until the Depth Range menu appears on- screen and use the UP ARROW to select AUTO. Depth Range Zoom. Zoom is similar to Depth Range because it controls the range of information displayed on screen. Zoom,

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 view even in quickly changing terrain,

The Fish Alarm alerts you to the presence of fish, or other targets not con- nected to the bottom. The Fish Alarm has three different settings that correspond to the three different size fish symbols shown on-screen. The default setting is “OFF.” With the “Large fish only” setting, the Tracker unit alarms on only those targets t

USING THE TRACKER UNIT MENU FUNCTIONS Triplog provides seven pieces of informa- tion: the current digital depth, water sur- face temperature, current boat speed, the distance traveled since the Tracker unit was powered up or reset, the average speed, the total time elapsed since power- up or reset, and the input voltage from your boat’s electrical system. The time, speed and distance calculations are useful for tracking your progress on a trip. The input voltage is useful for deter- mining the c

With Fish ID OFF, sonar returns are displayed as “raw” information. There is no interpretation made by the unit. Selecting ID OFF also disables the fish alarm. ID+ ON enables the Tracker unit to interpret the raw sonar data and, using a variety of techniques, depict appropriate target returns as one of three different size fish symbols. Further identific
