2D BEAM SELECT
2D Beam Select
sets which sonar returns
from the transducer will be displayed on the screen.
When Beam Select is set to
455 kHz
, the returns from the 455 kHz narrow beams will
be displayed in all views, and the maximum depth capability of your unit will be 240
ft (75 m).
When set to
83 kHz
, the returns from the 83 kHz wide beam will be displayed in all
views, except for the 3D/2D Combo View, which will continue to display returns from
both beams in their respective windows. The RTS® Window will display the returns
from the 83 kHz wide beam.
NOTE:
It is important to re-set 2D Beam Select to 455 kHz when returning to water
shallower than 240 ft (75 m) for maximum performance in the 3D views.
To change Beam Select:
1. Highlight Beam Select on the Sonar main menu.
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to select either the 455 kHz
beam or the 83kHz beam. (455 kHz, 83 kHz, Default = 455 kHz)
FISH ID+™
Fish ID+™
uses advanced signal processing
to interpret sonar returns, and will display a Fish Symbol when very selective
requirements are met. When a fish is detected, a fish icon and its depth are displayed
above the return that has been classified as being a fish. Fish symbols come in three
different sizes to indicate the intensity of the return; in addition, there is a unique
symbol set associated with each of the six beams, for a total of 18 possible fish symbols
which can be displayed. The following graphic illustrates the different Fish ID+™
symbols and shows the beams with which they are associated. For instance, a hollow
fish facing left indicates it was detected in the far left beam and a hollow fish facing
right indicates it was detected in the far right beam.
When Fish ID+™ is turned off, and 83 kHz returns are displayed, the 900 series™ shows
only the raw sonar returns on the display.
To set Fish ID+™:
1. Highlight Fish ID+ on the Sonar main menu.
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Fish ID+ setting.
(3D Markers, Symbol Only, Depth, Off, Default = 3D Markers)
