Note
False echoes
For details on avoiding false echoes, see SHAPER MODE (2.8.4) (Page 127).
● Avoid central locations on tall, narrow vessels
Beam angle
● Beam angle is the width of the cone where the energy density is half of the peak energy
density.
● The peak energy density is directly in front of and in line with the antenna.
● There is a signal transmitted outside the beam angle, therefore false targets may be
detected.
Emission cone
● Keep emission cone free of interference from ladders, pipes, I-beams, or filling streams.
