Yes, CHIRP is better than sonar. CHIRP sonar generates an image using a wider range of frequencies, which allows the processor to produce a much more accurate and detailed sonar image of fish, structure, or the bottom. Where a traditional sonar emitting a single frequency shows a school of fishes as a single blob or cluster, a CHIRP sonar individualizes each fish, making it much easier to distinguish between fishes and other surfaces. CHIRP sounders provide a greater separation and distinction between fishes and other objects.
