For Best Performance
Use the following tips and examples to help you interpret the Side Imaging®
display.
Boat speed: Side Imaging® is best performed at boat speeds between 2 to 6
mph. If the boat is stationary, the same information is displayed over and over.
If the boat is moving very quickly, there will be gaps between the strips of
information. The best boat speed to use will depend on the side range selected.
Slower speeds are good for longer ranges, while faster speeds can be used at
shorter ranges.
Boat navigation: It is important to understand that when the boat turns,
successive beam strips to one side will begin to overlap and the strips on the
other side will fan out, providing some distortion to the image.
Because of this, the best imaging performance is produced by straight line
navigation and minimal side-to-side boat motion (i.e. wave induced, etc.). This
applies to navigation by either the main engine or the trolling motor. Minimize
turning time and avoid wave action that induces large side-to-side rocking of
the boat. For example, if there is a lot of wave activity, try to move the boat so
that it is perpendicular to the waves instead of parallel with the waves in order
to minimize the side-to-side rocking of the boat.
For Best Side Imaging® Performance
Boat speed: 2 to 6 mph
Straight line navigation
Minimum turning time and wave turbulence
