SONAR SYSTEM SUMMARY
An echo sounder is only able to search in one direction within some beam angle, beneath
the ship. A sonar, however, can freely search the broad range, since the transducer’s
angle can be varied not only the horizontal direction but also the vertical direction.
SONAR DISPLAY RANGE ECHO SOUNDER DISPLAY RANGE
HORIZONTAL ANGLE (SECTOR) 180° WHEN DETECTING
