FishTrack
FishTrack shows the depth of a fish symbol when it appears on the dis-
play. This lets you accurately gauge the depth of targets. This feature is
available only when the Fish I.D. feature is on. The default setting for
FishTrack is off.
To turn on FishTrack:
(Note: These instructions will turn on FishTrack and Fish I.D. at the
same time.)
1. From the Sonar Page, press
MENU|↓ to SONAR FEATURES|ENT.
2. Press ↓ to
DEPTHS|ENT|EXIT|EXIT.
To turn off FishTrack, repeat the instructions in step 1. Turning off
FishTrack will not turn off Fish ID.

Frequency (Change Transducer Frequency)
The SeaCharter 502cDF transducer operates with both 200 kHz and 50
kHz. The 200 kHz frequency has a 12° cone angle and the 50 kHz fre-
quency has a 35° cone angle.
The default frequency is 200 kHz, which is best for use in shallow water
(about 300 feet or less). This frequency is the best choice for about 80
percent of the fresh and salt water sport fishing applications. When you
get into very deep salt water, 300 to 500 feet or deeper, the 50 kHz fre-
quency is the best choice.
The 200 kHz transducer will give you better detail and definition, but
less depth penetration. The 50 kHz transducer will give you greater
depth penetration, but a little less detail and less definition. (Remember,
all sonar units typically read deeper in fresh water than in salt water.)
