Down Imaging View - Humminbird HELIX 5 SI GPS Operation Manual

Down Imaging View

Down Imaging View displays the down beam portion of the data from the Side Imaging beams.
The Down Imaging results are displayed in 2D format. Sonar returns are charted on the right side
of the display. As new information is received, the historical information scrolls left across the
display. See What's on the Down Imaging Display for more information.
• Coverage: The Down Imaging coverage is always very thin front to back, and the side to
side width can be adjusted (see Sonar Menu Tab: Down Imaging Beam Width).
• Down Imaging X-Press Menu: Press the MENU key once to access the Down Imaging
X-Press Menu. You can set the sensitivity of the sonar to see more or less detail, the chart
scrolling speed, the display color palette, and the Upper Range and Lower Range (see
Down Imaging X-Press Menu).
• Freeze Frame: Press any arrow on the 4-WAY Cursor Control key, and the Down Imaging
View will freeze and a cursor will appear on the screen. Use the 4-WAY Cursor Control key
to move the cursor over a sonar return, and observe the following:
- The depth of the sonar return you choose will be displayed in the cursor information
box.
- Zoom+: Press the ZOOM+ key, and a zoom box will appear and magnify the area you
choose, providing more detail in the individual sonar returns. The zoom scale will
increase or decrease as you press + or - repeatedly. Press EXIT to remove the zoom
box and return to Down Imaging View.
