Chirp Downvision Overview - Raymarine RVX1000 Installation Instructions Manual

CHIRP DownVision
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.
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.
