Rather than building a 3D image, the 2D display provides an instant picture of the
seabed in front of the vehicle. Only one image is used so the display updates very
quickly, even at longer ranges, which allows the ROV to be piloted using the screen.
4.5.1. Search Mode
Normally the Eclipse transmits a thin 1.5° by 120° beam which is useful for:
• Measurements between vertical targets are required.
• Only a small part of the total image is of interest.
• Long ranges are required (up to 120m depending on water conditions).
By enabling
Search Mode
, Eclipse will transmit a thicker beam (40° by 120°).
This mode illuminates all of the area in front of the sonar and is used as a general
forward looking sonar (maximum range 60m).
