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.
How to open
This dialog box is opened from the Display menu.

Description
In the Profiling Settings dialog box, you can choose to display only the sonar view, only the 3D Point Cloud, or both. The profile point data can be exported to a file so that third-party software can extract depth, distance, and volume measurements.
Details
Display Mode
•  Image
Select if you want to update the sonar view only.
•  Image and Profile
Select if you want to update both the sonar view and the 3D Point Cloud.
•  Profile Only
Select if you want to display only the profile points in the sonar view and 3D Point Cloud.
Point Size
Select the size of the displayed profile points.
Algorithm
Select the profiling algorithm. The default setting is optimal for most conditions.
The Split Beam algorithm will improve point detection with sub-degree accuracy at a low grazing angle (but with the compromise of a lower ping rate).
Select the Structure algorithm for high-resolution structure inspections at short or medium ranges. For structure inspections, your sonar is usually orientated upward or looking sideways – this algorithm takes this orientation into account and adjusts the profiling points accordingly.
Point Selection
Select which profile points to display. You can choose to display only the points closest to the sonar transducer origin, or only the points with the strongest signal returns.
Parameters
•  Max Depth
Drag the slider to set the upper depth limit of the profile points. No profile points will be detected above this depth.
A red line overlay will appear in the sonar view to indicate the max depth (view the result in the 3D Point Cloud window).
•  Min Depth
Drag the slider to set the lower depth limit of the profile points. No profile points will be detected below this depth.
A green line overlay will appear in the sonar view to indicate the min depth (view the result in the 3D Point Cloud window).
•  Clutter Suppression
This feature removes the number of detected noise profile points. If the box is unchecked, the system will automatically adjust the clutter suppression. You can choose your own clutter suppression percentage by checking the box and dragging the slider. Setting the suppression to zero will disable this feature. Setting the suppression to 100 will suppress all noise detections.
•  Max Sector
Drag the slider to set the upper angle limit of the profile points. No profile points will be detected above this angle.
•  Min Sector
Drag the slider to set the lower angle limit of the profile points. No profile points will be detected below this angle.
Depth Tracking
Check this box to automatically adjust the range according to the current depth when the head is running. This feature is only available if Image and Profile or Profile Only is selected for the Display Mode.
Note
When the head is running, the estimated depth below the Sonar Head is shown in real time. During playback, the recorded depth is shown.
