Humminbird 150SX, Operation Manual

Increasing the value to a number greater than zero shows more fish
symbols on-screen. In this case smaller sonar returns will be depicted as fish
symbols. This is useful for identifying many smaller sonar returns (such as
baitfish) as fish symbols.
Decreasing the value to a number less than zero shows fewer fish symbols
on-screen. In this case smaller sonar returns are disregarded. This is useful
for eliminating many small sonar returns when seeking larger species of
fish.
The 150SX remembers this selection even when the unit is powered off.
Numeral Size. Two options are available: BIG and SMALL. The factory
setting is BIG. With this setting, the digital depth and speed and temp
numerals are drawn large enough to be read from across the boat. The
big numerals occupy space on the display that could be used for the
graphics area. Hence, the small numerals
option. With small numerals selected,
a greater amount of the display area
is available for the graphic view.
This effectively increases the display
resolution of the unit.
Numeral Size settings are remembered
when powered off.
Diagnostic. Two options are available: HIDE and
SHOW. The factory setting is HIDE. Selecting
SHOW brings up the Diagnostic screen. See the
Using Diagnostic section for more information.
Units. The Units function allows the user to select
the units of measurement for the depth. Choose
between FEET and METERS using the UP or
DOWN ARROW buttons. The 150DX remembers
this selection even when the unit is powered off.
