USING THE TRACKER UNIT
MENU FUNCTIONS
the boat. The big numerals occupy space on the display that could be used for the graphics area. Hence, the small numerals option. With small numer- als selected, a greater amount of the display area is available for the graph- ic view. This effectively increases the display resolution of the unit.
Numeral Size settings are remembered when powered off.
Diagnostic. Two options are available: HIDE and 
SHOW. The factory setting is HIDE. Selecting SHOW 
brings up the Diagnostic screen. See the Using Diag- 
nostic section for more information.
Units. The Units function allows the user to select 
the units of measurement for the depth and speed
readout. FEET/MPH (feet/statute miles per hour) and FEET/KTS (feet/nautical miles per hour), are available.The Tracker unit remembers this selection even
when the unit is powered off.
Speed Offset. The Speed Offset option allows
the user to compensate for differences in hull
design, and its effect on the accuracy of the
speed measurement.
If there is a discrepancy between the indicated speed and another speed measurement device on the boat, the speed measurement can be var- ied to improve accuracy. Remember, the speed paddle wheel measures speed through the water,
not speed over ground.
Speed offset is remembered after power is disconnected.
Depth Offset. The Depth Offset allows the user to select the point on the boat from which the depth measurement is made. Selecting a positive value adds distance to the measurement. If the transducer is mounted 3 feet beneath the water- line, a positive 3 will show the correct depth from the surface of the water.
