file on a never-ending loop.
|
• | 3D Point Cloud Click to show or hide the 3D Point Cloud window. The 3D Point Cloud presents profile point data that can be rotated in three dimensions.
|
• | Profiling Settings Click to show or hide the Profiling Settings dialog box. Profiling mode allows you to view a real-time 3D point cloud of the sea bottom or structures under the water.
|

|
• | Font Size You can choose between using a normal or a large font size throughout the M3 software.
|
• | Palette Select Palette to choose your preferred echo colours. Which colour scale to use is mainly a personal preference based on ambient light conditions, the nature of the echoes and
your own experience.

|
• | Heading Overlay If your Sonar Head is forward looking, click Heading Overlay to enable or disable this feature. When this feature is enabled, the degree annotations in the sonar view will change to reflect the current sonar heading.

• | Speckle Filter Click Speckle Filter to enable or disable this function. This filter reduces noise (the grainy “salt-and-pepper” pattern) in uniform areas of the sonar view. Distinguishable details
in features and targets will be retained.
|
• | Sidelobe Reduction Click Sidelobe Reduction to enable or disable automatic sidelobe reduction. This function improves overall image quality by reducing the sidelobes of strong targets. Sidelobe reduction is especially useful at short ranges when targets are very close. In addition, the automatic adjustments work well when the sonar is constantly moving, such as on an ROV.
Tip
If you have a software license for advanced features, you can view the automatically-calculated sidelobe reduction ratio or
manually adjust the ratio using a slider.
|
• | Reset to Default Layout Click to reset the presentation layout. All windows and dialog boxes will be docked in their default location. In addition, some display elements are hidden by default.
