Softkeys
Instructions in this manual are based on HDS unit menus, not softkeys. If you have
an HDS-8 or HDS-10, you can get the same results using the softkeys.
To use softkeys:
Touch the desired softkey to change settings, view a softkey menu 1.
or adjustment scrollbar.
Use the keypad to select menu items and make adjustments to 2.
scrollbars. Press EXIT to close softkey menus.
NOTE: After making adjustments to options or settings, use the EXIT
key to resume normal operation.
StructureScan
Consists of two powerful sonar views: Sidescan and Downscan. Used in conjunction
with the built-in broadband sounder, StructureScan gives you an underwater
panoramic view.
Sidescan
Sidescan
Broadcasts a sonar beam to each side of your boat allowing you to view structure,
and terrain without having to drive your boat over the top of it.

Page 5
You can use Sidescan to:
Save waypoints at objects/locations off to side of the boat •
Review history•
Measure the size of underwater objects and the distance from one •
object/location to another object/location using live Sidescan returns
or Sidescan history
Create sonar logs•
Use two frequencies: 455 kHz (more distance) and 800 kHz (better •
denition)
Downscan
Uses the same technology as sidescan, but broadcasts the beam downward, giving
you the same high resolution in a familiar right to left display.
You can use Downscan to:
See different view of objects/locations selected with cursor on •
Sidescan panel
Save waypoints •
Review history and create sonar logs•
Use two frequencies: 455 kHz (greater depth) and 800 kHz (better •
denition)
Overlay Downscan imaging on the sonar page •
