The range setting determines the water depth that is visible on the screen.
Auto range
When the range is set to Auto the system will automatically set the range depending on
the water depth.
Preset range levels
You can select between several preset range levels.
When manually changing the range the upper depth line will always be at the water
surface. These options allows you to focus on echoes at the upper part of the water
column.
StructureScan™ Frequencies
StructureScan supports two frequencies. 455 kHz is ideal for greater depth penetration
and while 800 kHz provides better definition especially at shallower depths.
