Horizontal Steering

This setting allows the operator to steer the swath independently of the sonar head physical 
angle. The extent of steering is determined by the angle selected. The limitation is that the outer 
beam cannot be steered past 5° from the horizontal (see 

Figure 7

). When the swath is steered 

this way, the individual beam widths increase with the steering angle. A beam steered at 60° is 
twice the width of a beam steered at 0°.
