What's On The Side Imaging Display - Humminbird 1157c Combo Installating And Operation Manual

What's on the Side Imaging Display

(1197c SI Combo models only)
Side Imaging displays a number of easily recognizable features that allow for accurate interpretation of
sonar return. For example, rock and gravel provide a clearer sonar return than mud and sand because of
that face away from the transducer. You can find a number of easily recognizable features on the Side
following items:
1 Depth - water depth; can be set to alarm when the
water becomes too shallow.
Temperature - water surface temperature
2
Speed - if a Speed accessory or GPS Receiver is
3
attached, the 1100 Series™ can display the speed
of the boat, and can keep a triplog of nautical or
statute miles traveled.
Course - the current direction the boat is traveling
4
measured in degrees from North.

7 Topography Changes
The water column shows the relative depth of the
8
water under the boat at a given time. Variations in the
width of the water column show variations in the
distance to the bottom as the boat passes over.
9 Shadows result from a lack of reflected sonar from
a particular area, and can be more valuable for
interpretation than the sonar reflected by the object
itself. Use shadows to help you see the image in 3
dimensions, oriented in space. You can gain insight
into the actual shape of an object, or the depth to
which it has sunk into the bottom, through shadows
on the display.
