Traditional sonar sends one frequency (e.g., 200 kHz). CHIRP (Compressed High-Intensity Radiated Pulse) sends a sweep of frequencies (e.g., 40-220 kHz). A "catfish finder" usually refers to one of

Catfish are ambush predators. They don’t chase prey over long distances; they wait for it to come to them. Therefore, "finding" catfish is less about wandering and more about identifying specific habitats.
