USING THE TRACKER UNIT
CONTROL FUNCTIONS
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 a large fish symbol.
Fish in Narrow Beam
ID+ adds an additional piece of informa-
tion 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. This is especially
helpful in setting bait depths or for downrigger operation.
The fish symbols indicate the sonar beam the fish is detected in. This gives you a reliable indicator of side to side location of the fish relative to the boat. Fish symbols that are hollow are detected in the wide beam and are around the boat. Solid fish symbols represent fish detected in the nar- row beam and are directly under the boat.
CONTROL FUNCTIONS
The Tracker unit 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 Tracker unit up for normal operation. When the unit is on, POWER turns the unit off. POWER can also be used to go directly into Simulator mode. To enter simulator, with the unit powered off, press and hold POWER for sever-
