FISHTRACKTM The FishTrack feature shows thedepth of afish symbol when it appears on thedisplay. This lets you accurately gaugethedepth of targets.This feature is available only whenthe Fish ID featureis on. The Fish l.D. feature identifies targets that meet certain conditions as fish. The micro-computer analyses all echoes and eliminates surface clutter, thermoclines, and othersignals that are undesirable. In most instances, remaining targetsare fish. The Fish l.D. feature displays symbols on the screen in placeofthe actual fish echoes. There are fourfishsymbolsizes: tiny, small, medium, and large. These are used to designate the relative size between targets. In otherwords, it displays a small fish symbolwhen it thinks atargetis a small fish, a mediumfish symbol on a largertarget, etc. To turn the FishTrack feature on, press the menu key, then press the key adjacent to the "Fish-ID On Off FishTrack" label untiltheblackboxsurrounds the "FishTrack" label.

This allows youto tell the difference between a hard and soft bottom. Forexample, a soft, muddy or weedy boftom returns a weakersignal whichisshown with a narrowor no gray line. A hard bottom returns a strong signal which causesawide gray line. If you have two signals of equal size, onewith gray and the other without, then the target with gray is the stronger signal.
