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.
Beam coverage: When there is an area directly under the boat that does not
have Side Imaging® beam coverage, this area will be covered by the standard
200/83 kHz down-looking beam and displayed in the Sonar views. The net
effect of this, on the display, is that a single object may appear as two separate
entities, when in reality, it is one continuous object.
