CHIRP (Compressed High-Intensity Radiated Pulse) sonar technology differs from traditional sonar in several key aspects. Traditional sonar sends out a single frequency pulse at a time, providing a snapshot of the underwater environment. On the other hand, CHIRP sonar sends out a continuous range of frequencies, from low to high, in a sweeping motion. This results in higher resolution images with better target separation and clarity. CHIRP sonar also offers improved depth penetration and can differentiate between closely spaced targets more effectively. Additionally, CHIRP sonar is better at filtering out noise and interference, leading to more accurate and detailed fish arches and bottom contours.
