Align Adjustment
In case the horizontal scanning transducer has been
mounted such that it points in a direction other than
dead ahead, Ultrascan PC90 can compensate for up to
14 degrees of misalignment in either the port or
starboard direction.
To set the Transducer Align correction, point the boat
directly toward a target (such as a piling, etc.) The
target should appear at the center of the horizontal
scanning display. If, however, the target is off to the
port (as shown on the “Before Align Adjust” picture
at right), it means that the transducer was mounted
pointing slightly in the starboard direction. If the
target is offset to the port by 7 degrees, the
Transducer Align correction should be 7 degrees
Stbd. If the target appears off to the right (Stbd),
adjust to the Port direction to bring the target back to
the center position.
After setting the Transducer Align, view the HORZ
display to verify the correction.
Keel Offset
If the transducer(s) are mounted in a position above
the deepest point of your boat’s keel, Ultrascan PC90
can automatically adjust the depth scale bars to
compensate for the offset. This will allow you to
always work with depths that are relative to the
bottom of your boat’s keel.
Move the slide bar to specify the depth of the keel
beneath the transducer(s).
