Processing Mode Drop Down Selector
The processing mode selection drop down sets the system's range and field of view while pinging.
Note: At
least one ping must be processed before this value can be changed.

Detect Bottom Check Box
If this check box is checked, then the processor will attempt to detect the bottom so that it may be drawn as
a surface in the 3D Sonar Display. If this check box is not checked, then there will be no surface drawn in the
3D Sonar View. This feature is useful when operating in water depths beyond 160 feet (approximately 50
meters) deep. If "Detect Bottom" is checked in deep water conditions, the processing software may falsely
interpret in-water targets as the bottom and create some strange images.
Note: If this check box is not
checked and there is a bottom, then that bottom may show up as a large number of targets, provided the
squelch is set to a low enough value.
Auto Squelch Check Box
If this check box is checked, then the processor will attempt to detect in-water targets automatically, without
considering the Squelch setting (see "Squelch Control"). Most of the time, the Auto Squelch mode will
perform better than manually setting the Squelch level.
Squelch Control
The 3D sonar processing technology that FarSounder has developed and integrated into the sonar systems
utilizes spatial classification and correlation techniques to identify particular targets as either part of the
sea floor/river bed or as an in-water target. The classification of targets into distinct target categories is an
