•
Depth
The vertical distance downwards from the water surface.
•
Heading
The direction in which a vessel is pointing, as opposed to the course made good.
•
Magnetic Variation
If you are using a magnetic heading sensor, enter the local magnetic variation
into the
Magnetic Variation
box to get true heading. This parameter can be
changed while the Sonar Head is running.
•
Pitch/Roll
Pitch is the up/down rotation of a vessel about its lateral axis. Roll is the tilting
rotation of a vessel about its longitudinal axis.
•
Heave
Heave is the linear vertical (up/down) motion of the vessel.
•
Sound Speed
This shows the current sound speed value, whether it is provided by a sensor,
calculated or entered manually. A sound speed sensor is required to accurately
measure in-water speed near the Sonar Head. This parameter can be changed
while the Sonar Head is running.
Check the
Override Sound Speed
box if you want to replace the sound speed
value in your recording with a fixed value during playback. This may be
necessary, for example, if your recorded sound speed is not accurate.
Note
You can override the sound speed in .mmb files only.

The mounting offsets are required to calibrate the position of the Sonar Head relative to
the GPS antenna. If you have a rotator, you must calibrate the position of the rotator
relative to the Sonar Head.
