17.8 RANGE MENU
Figure 17.8 - Range menu
17.8.0 Range Mode
Selects among Manual, Auto Range and Bottom Lock.
17.8.0.0 Manual Mode
Used to set the depth Range (from the surface) the Fish Finder display will show.
17.8.0.1 Auto Range
The Fish Finder determines automatically the Range as to keep the bottom visible in the
lower bottom of the screen. In this mode, Shift is always set to 0.
17.8.0.2 Bottom Lock
The Bottom Lock function keeps the screen display locked onto a certain Range around the
bottom. Let’s say the bottom is 400Ft and the Bottom Lock Range is set to display 30Ft
around the bottom, the screen (instead of displaying from 0Ft to e.g. 450Ft) will display only
a Range of 30Ft around the bottom, e.g. from 380Ft to 410Ft.
17.8.1 Depth
Moves the display from showing the bottom to the depth value entered.
17.8.2 Shift
Shifts the display from the bottom of the transducer to the depth value entered.
Example: Your vessel is in about 57Ft of water, however there is fish suspended in 35Ft
of water. You want to display to 10Ft area around the fish. Shift would be set to
25Ft and Depth would be set to 35Ft shown in example below.
