SideVision® overview
CHIRPSideVision™ overviewSideVision® technology interprets signals from a pair of side-looking transducers, and builds up a detailed underwater view as your vessel moves forward.
The transducers send pulses of sound waves into the water on each side of your vessel, and record the sound waves that reflect off the bottom, and off objects on the bottom or suspended in the water column. The received echoes are affected by the bottom material (for example mud, gravel, or rock), and by any other objects in their path (for example, cables on the sea floor, bridge piers, wrecks, shoals, or fish).
SideVision® beams
SideVision® produces 2 wide-angle side-to-side beams, each with a thin fore-to-aft beam. The coverage of the SideVision® beams is a swath on each side of the vessel.
SideVision® is effective at lower vessel speeds. The wide, thin beams produce clear target returns. As your vessel moves forward, subsequent returns build up to provide an image of the sea floor on each side of your vessel.
The use of CHIRP processing and a high operating frequency provide a detailed image, making it easier to identify bottom structures around which fish may reside. The narrow angle the beams make with the bottom at longer ranges can reveal the shadows of structures that protrude from the bottom.
