Strength[dB]
Float Averaged signal from the four beams. The signal strength is calculated for each
beam for each ping and averaged at the end of the interval.
Horizontal Speed
AutoBeam [cm/s]
Float Horizontal speed from the Autobeam solution. The best data found automatically
from the different beam solutions. Introduced from software version 8.2.1
Direction
AutoBeam[Deg.M]
The current direction calculated from the 4 beams combined with compass
heading to determine the current direction. Introduced from software version 8.2.1
