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

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.

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 •

denition)

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 •

denition)

Overlay Downscan imaging on the sonar page •
