Custom — Upper and Lower Limits
Controls not only the depth range (lower limit), but
also lets you choose the upper limit. So, instead of
a selecting a range that includes the water surface,
you can choose upper and lower limits anywhere
along the water column.
To set Upper and Lower Limits:
1. Select Range and press ENTER.
2. Highlight Custom and press ENTER.
The Upper and Lower Limit window
will appear.
3. Select the Upper or Lower Limit dialog box. Press ENTER. The
numerical keypad will appear.
4. Use the keypad to enter the desired value in the corresponding
upper or lower limit dialog box. Press ENTER.
5. Repeat Steps 3 and 4 to input the desired limit in the other dialog
box.
Ping Speed
Ping Speed controls the rate the transducer uses to
send sonar waves into the water. A higher ping speed
will yield the best results when you are moving across
the water at a high rate of speed or shing from a dock. The reverberation of too
much ping speed can cause interference on the screen.
When using two units on your boat, lowering the ping speed of one of the units will
prevent interference (cross-talk) caused by one transducer detecting pings from the
other transducer. The default setting is suitable for most conditions. Highlight Ping
Speed on the Sonar menu and press the keypad left/right to make adjustments.
Sonar Options
Adjusts display settings and the conguration of the display.
The Sonar Options menu allows you to split the screen
between two sonar views, change the color of the display,
use Fish ID and add graphical elements to screen that will
enhance your sonar experience.
To access the Sonar Options menu, select Sonar Options
from the sonar menu and press ENTER.
Upper limit is 15’ (4.5m); lower
limit is 65’ (19m).
