DownVision™ overview
DownVision™ produces a wide-angle side-to-side beam and a thin fore-to-aft beam.
The coverage of the DownVision™ beam is a water column directly beneath and to the sides of the
vessel.
CHIRPDownVision™ overview
Figure 1. DownVision™ beam
DownVision™ is effective at lower vessel speeds. In deeper waters the CHIRP bandwidth is automatically optimized to improve bottom lock and the detection of moving objects (e.g. fish) in the wider water column.
The wide, thin beam produces clear target returns. The use of CHIRP processing and a higher operating frequency provide a more detailed image, making it easier to identify bottom structures around which fish may reside.
