We're pleased to announce availability of a software update for the DFF3D Multi-Beam 3D Sonar. As of July 10th, all DFF3Ds are being shipped with version 1.05 software, which changes the default settings along with TVG (Time Varied Gain) parameters to improve fish detection at all ranges.
Improved Default Settings
The default beam angle and beam width have been changed to effectively cover 120°. The default clutter has also been changed from 0 to 25 to show individual fish and groups of fish more clearly, while suppressing noise and weak targets when in manual gain mode.
