When using a fish finder for catfish, it's essential to understand how to interpret the information it provides. Look for areas with structures like submerged trees, rocks, or drop-offs where catfish like to hide. Catfish are bottom feeders, so set your fish finder to display the bottom structure clearly. Pay attention to any arches or thick lines on the screen, as they could indicate schools of catfish. Additionally, use the fish finder's depth and temperature readings to locate the catfish's preferred habitat. Experiment with different frequencies and sensitivity settings to fine-tune your fish finder for catfish.
