Thumbs up CHIRP SONAR..EXAMPLES..and FYI

From Garmin;

CHIRP is the most sophisticated sonar technology available for use by the fishing and boating public. The word itself is an acronym for Compressed High-Intensity Radiated Pulse.

Standard Sonar
Standard sonar sends 1 single frequency at a time. Since the only feedback is from this 1 single frequency, there is little information to work with, limiting the clarity and resolution available with standard sonar.




CHIRP Sonar

Instead of sending just 1 single frequency, CHIRP sends a continuous sweep of frequencies ranging from low to high. CHIRP sonar technology then interprets frequencies individually upon their return. Since this continuous sweep of frequencies provides CHIRP with a much wider range of information, CHIRP sonar is able to create a much clearer, higher resolution image.







Improved target resolution enables you to distinguish fish hovering just above bottom.




Improved target resolution enables you to actually see individual baitfish separately.




Improved target resolution enables you to differentiate between big fish and tight clusters of baitfish.




A sweep of tones delivers more data, providing a much higher resolution, clearer depiction of targets on screen.
