Freeze Frame; Bottom Presentation - Humminbird 531427-1_D Operation Manual

Freeze Frame

Freeze Frame - Pressing any arrow on the 4-WAY Cursor Control key will freeze the screen and a
cursor will be displayed on the screen. The cursor can be positioned on the display using the
4-WAY Cursor Control key to determine the depth of any sonar return. The RTS® Window
continues to update in Freeze Frame. In addition, see the effects of menu setting changes with
Instant Image Update. Pressing EXIT will exit Freeze Frame and the display will start to scroll.
Freeze Frame is available in the Sonar, Sonar Zoom, and 200/83 kHz Split Sonar Views.

Bottom Presentation

As the boat moves, the unit charts the changes in depth on the display to create a profile of the
Bottom Contour. The type of bottom can be determined from the return charted on the display.
A Hard Bottom such as compacted sediment or flat rock appears as a thinner line across the
display. A Soft Bottom such as mud or sand appears as a thicker line across the display. Rocky
Bottoms have a broken, random appearance.
