USING THE 105SX
MENU FUNCTIONS
After an adjustment is made, the menu disappears and the new
sensitivity setting is in affect. If additional time is needed to study a
menu, press and hold the MENU button and the menu will remain on-
screen indefinitely. If you need to make an additional adjustment, press
the UP ARROW or DOWN ARROW button.
Depth Range. The Depth Range function
controls the vertical distance displayed on
the graphic area of the display. There are
nine depth ranges available. The top of
the range is always 0, or the surface of
the water. Ranges of 0–15', 0–30', 0–60',
0–120', 0–180', 0–240', 0–360', 0–480' and 0–600' are available. The
range that positions the bottom depiction closest to the bottom of the
screen, will best utilize the available display resolution.
The 105SX automatically adjusts the
depth range depending on the depth of
the water. The unit tries to maintain the
bottom depiction about
2 /
3
down the total
range (for example, in 20' (6m) of water,
the 0-30' (0-10m) range would be
selected). This provides the best display
resolution and therefore the best target
separation possible.
The Depth Range can be adjusted manually. Press MENU repeatedly until
the Depth Range menu is visible. Two options are available:
Auto and Manual.
The manual setting enables you to adjust
the current depth range setting. The unit
no longer adjusts the Depth Range to the
most appropriate range for bottom display.
Often, the bottom may not be visible on-
screen. The digital depth readout always
determines the depth of the bottom, even
if it is not visible on-screen.
