Simrad ES38-10
Observe the horizontal and vertical distances (X and Y) between
the keel and the transducer blister. On a medium sized vessel, the
horizontal distance (X) should be approximately 1 meter. The
vertical distance (Y) must in general be as small as possible. This
is important to prevent the keel from shadowing the transducer
beam in shallow waters.
