Raymarine Dragonfly 7" sonar images to share

I captured a few recent sonar images in winter time fishing in DC with my Raymarine dragonfly 7" chirp fishfinder with down vision, so posting them to share and get your thoughts

here are the images

I think there's a little misconception in how sonar data is plotted onto the screen ...

Turn up the chart speed and they will be even bigger!

I agree that relative of the fish to my boat does affect the fish real size. For example, I most likely overestimated the fish size when the fish swim away from the boat in a faster speed vs my boat speed. My calculation would most likely underestimate the fish size if the fish swim towards my boat in a faster speed vs. my boat speed. I was in a canoe, and drifting with very little wind at 0.1 mph. Fish probably swim faster than my canoe.

Best to overestimate. It keeps your " interester" stimulated.
