Insignia 105SX - Manual (Page 21)

Bottom Black. There are two
selections available: Off and On. The
factory setting is Off. With this setting,
the 105SX displays the bottom using
Structure ID. This allows you to
determine the texture and relative
hardness of the bottom. Selecting
Bottom Black “ON” causes the unit to
blacken in the display below the
bottom. This gives the user easiest
recognition of the bottom location,
even from a great distance.
The 105SX remembers the Bottom
Black setting when powered off.
Fish ID. There are three selections
available: Off, ID+ ON, and Adjust. The
factory setting is ID+ On. With Fish ID
Off, sonar returns are displayed as
“raw” information. There is no inter-
pretation made by the unit. Selecting ID
Off also disables the fish alarm.
ID+ On enables the 105SX to interpret
the raw sonar data and, using a variety
of techniques, depict appropriate
target returns as one of three different
size fish symbols. The 105SX also
displays the depth beneath the surface
with the corresponding fish symbol.
Selecting Adjust and making
incremental changes enhances the
fishfinder’s ability to identify sonar
returns as fish symbols.
Increasing the value to a number
greater than zero shows more fish
