    Default 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

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

    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.
