I met a guy at the boat ramp with a Humminbird Side Imaging unit. I couldn’t see it work since his boat was already on the trailer, but the way he described it made me think it would be perfect for getting a good look at submerged catfish cover. Just like looking at black and white pictures he said.
I’ve always wondered if the cover that looked the best above the water was really the best underwater.
Anybody know anything about these units?
